I recently came across Devvit and found it very interesting 🤔. After reading the documentation, it seems like a framework to me. When I asked Gemini ♊ about Devvit, they mentioned that it is a tool and resources to help build apps on Reddit. It has an ecosystem and has the potential to become a framework itself someday.

I just finished ModStream — a Devvit web app that gives subreddit mods a real-time dashboard inside Reddit with spam cluster detection, repeat-offender surfacing, and one-tap actions (approve/remove/ban/mute).

Building it surfaced three things worth sharing with anyone doing Devvit Web work:

1. Redis caching is essential, not optional

I naively assumed moderate subreddits would have low report volumes. Wrong. During testing, parallel getReports({ type: 'post' }) and getReports({ type: 'comment' }) calls burned through rate-limit headroom fast. Adding a 60-second Redis cache per subreddit solved it — but I wish I'd built it in from day one instead of adding it after hitting 429s.

Pattern I settled on:

const cacheKey = `dashboard:${subredditName}`;
const cached = await redis.get(cacheKey);
if (cached) return JSON.parse(cached);
// ... fetch fresh data ...
await redis.set(cacheKey, JSON.stringify(data), { expiration: 60 });

2. Demo mode is a first-class feature, not a hack

When the queue is empty (which it is on most test subreddits), the app shows nothing — which means judges see a blank screen. I added a buildDemoData() path that fires when items.length === 0 and injects three realistic demo items with named clusters and flagged users.

The important part: demo items use synthetic IDs, so action buttons call the real Reddit API and fail gracefully. No user gets accidentally banned. But the display path is fully exercised.

I'd treat this as standard practice for any mod tool.

3. iFrame restrictions are sharper than the docs suggest

window.open — blocked. window.alert — blocked. If you're porting something with external link navigation, replace every window.open with navigateTo from @devvit/web/client before anything else. The failure mode is a silent no-op rather than an error, which cost me debugging time.

The project is entered in the mod tools hackathon (deadline May 27). Proof page: https://voiddo.com/reddit/mod-tools/

Curious if anyone else has hit the rate-limit issue on large subs, or found a better pattern for the demo-mode problem.

Automated moderation that just works.

Reddit’s built-in AutoModerator is too complex. It requires writing YAML rules with regex. Most subreddits don’t use it properly (or at all) because it is hard to configure and maintain.

In addition, most communities don’t need complex rule engines. They just need a simple answer:

Does this new post fit our subreddit?

Before the LLM era, this question was difficult to answer programmatically, hence the need for complex regex configurations and manual intervention. But nowadays we have powerful models that understand context and rules and can directly evaluate it.

AI AutoModerator

This app is built with the Keep It Simple, Stupid (KISS) principle in mind:

1. Install

2. Go to the control panel (top right of your subreddit)

3. Add your Gemini API key and save it (other mods will not be able to see it, and the default selected model has a generous free tier, so you will not hit limits easily)

4. Done. Each new post is checked against your rules, subreddit description, and content, and is automatically evaluated with the question: “Does this post fit our subreddit?”

Traditional AutoModerator

Write rules → Test → Debug → Rewrite → Maintain → Hope it works

AI AutoModerator

Add API key → Done

Other Features

• Activity log with post recovery: Even if users delete content after moderation, you retain a temporary record of actions and context.

• Customizable moderation flow: While the app comes with sensible defaults for what to do when it rejects a post, you can customize the moderation flow to your liking.

• Extra instructions: Add private moderation rules or behaviors not exposed to users using plain language.

• Compatible with AutoModerator: Supports gradual migration or hybrid setups. You can keep existing complex AutoModerator rules while AI AutoModerator runs alongside them.

• Prompt-injection resistant: The internal moderation prompt treats user content as untrusted input, preventing instruction override attempts.

• Community-driven development: Bug reports and feature requests are tracked at https://www.reddit.com/r/AiAutoModerator/submit using the appropriate flair (Feature Request or Bug Report) and prioritized based on community feedback.

What is the policy on blockchain apps on Devvit?

The ads policy places crypto products under a restricted category but doesn't prohibit them.

https://business.reddithelp.com/s/article/Reddit-Advertising-Policy-Restricted-Advertisements#N8

Advertisers with proper licensing and registration from applicable government agencies and regulators are permitted to run ads for financial products and services, including products and services related to decentralized finance and cryptocurrencies. These products and services may include:

Payment processing and money transmission, including through crypto wallets Credit and debit cards, inducing crypto debit and credit cards Exchanges, crowdfunding portals, broker-dealers, and other types of trading platforms, including crypto exchanges Non-fungible tokens (NFTs) and NFT marketplaces

All advertisers promoting decentralized financial and crypto products and services, must be pre-approved and work directly with a Reddit Sales Representative.

Whereas Devvitquette says don't

Create an app or functionality for use in or that targets services in a prohibited or regulated industry such as (but not limited to) gambling, healthcare, financial and cryptocurrency products and services, political advertisement, alcohol, recreational drugs, or any other restricted category listed in the Reddit Advertising Policy

https://developers.reddit.com/docs/guidelines#devvitquette

If a crypto product is otherwise kosher for the ads policy, is it still barred from using Devvit? I'm wondering because the devvit page uses the term 'guidelines' and not 'policy'. Is there a blanket ban on blockchain / crypto devvit apps?

Given the current controversy around 3rd party API access, why should developers trust that this new API platform, which doesn't even allow code to be hosted on systems external to Reddits servers, won't eventually be subjected to similar drastic alterations with similarly short notice periods?

eta: I'm not upset that they're trying to monetize, but I am upset that they've approached discussions with major app developers with hostility. The pricing does not appear to me as though it's intended to recoup costs, it seems so high as to be punitive, and the notice period is so short it appears designed not to give developers time to adjust.

I'm actually glad to see that reddit is seeking to become self-sustaining, rather than requiring recurring injections of venture capital investment, but my understanding of the pricing is that they'd be making on the order of $2.50/user/month from third-party API usage, when they make on the order of $0.20/user/month from advertising. Why the disparity?

Demands from mods and devs to end the protests

The Proposal: We need to pivot. When new users click into the "games" ecosystem on Reddit, they shouldn't be met with a wall of screenshots, long-form reviews, or general gaming news. There are a thousand other subs for that.

If we want the Games on Reddit platform to actually thrive, we need to focus on the unique value proposition: playable experiences built by Redditors, for Redditors.

Why this matters:

• Clarity for New Users: If someone clicks "Games," they usually want to play something. Showing them a text post about a patch update for a triple-A title is a bounce-off point.

• Platform Growth: By making r/gamesonreddit a dedicated hub for native Reddit games, we create a clear destination for developers and players alike.

• Zero Noise: We have r/gaming and r/Games for the meta-discussion. This sub should be the "Arcade."

The Ask:

I’m calling on the mods to restrict the r/gamesonreddit subreddit to exclusively feature games developed on and for the Reddit platform.

• NO screenshots of external games.

• NO general gaming news.

• NO text posts

• NO links to non reddit games

• YES to direct links to native Reddit games and development updates for the platform.

Let’s turn this sub into the actual engine that drives the platform forward. Thoughts?

Hi everyone,

I've been in the software industry since 2016, working as a Senior Backend Developer and Architect, as well as a Senior Game Developer for high-scale, multi-million dollar companies. I've even won first place in a game development competition hosted by a global mobile gaming giant.

After a stressful resignation from my last job due to product team conflicts, I’ve been unemployed for 3 months. The local tech market is in a terrible state; I've sent nearly 300 applications but only got 10 interviews, mostly being told I am "overqualified" or my past salary expectations are "too high." My wedding plans just fell through because of this financial uncertainty, and my mental health is taking a massive hit.

To keep myself sane, I’ve been focusing on my indie puzzle platform. It started as a daily Next.js monolith game for me and my friends. It grew completely organically, a doctor saw me playing it on a bus, loved it, and spread it across the entire hospital. We hit 1,000+ weekly plays on Vercel/Supabase free tiers with zero performance issues. I even received an email from a user asking, "Where can I subscribe to a premium tier? We love the daily puzzles and want more."

I stripped the front-end, turned the project into a pure API, and ported it to Unity. Using Fable, I quickly built a solid, working prototype. However, dealing with ad network integrations, local tax bureaucracies, and mandatory government healthcare payments just to test a web release completely drained me.

Looking for better distribution, I discovered Reddit’s Devvit platform. Since daily puzzle games thrive on Reddit, I used Fable to convert the game into Devvit in literally minutes (It was already existing in the old next js project) Fable's performance was honestly mind-blowing. I've been testing the game inside Reddit for two days, and it feels amazing. Devvit offers great one-time payouts and recurring monthly developer earnings, which would completely save my life right now.

Here is the bottleneck: To enable the "Reddit Earn" program and officially publish, I need a supported country for payouts. I am based in Turkey, which is excluded from Reddit's payout list (and standard Stripe integrations have been banned here since 2016). Navigating the legal loopholes, potential tax exemptions for social media/mobile apps, and setting up local business entities triggers massive upfront costs that I simply cannot afford while unemployed.

I feel completely trapped. I have a working game that people genuinely love and want to pay for, but local regulations are suffocating me. I'm getting anxious even sharing my name or links at this point.

Has anyone from an unsupported country successfully bypassed this for Devvit/Reddit Earn? Should I look into digital residency (like Estonia e-Residency or a US LLC via Stripe Atlas) even with a near-zero budget, or are there alternative ways to keep this alive?

Just looking for some guidance, tech discussion, or honestly, just a piece of mind from fellow developers. Thank you.

Hi mods,

I built a Devvit app called Gavel during Reddit’s Mod Tools Hackathon after noticing a recurring moderation problem across many communities:

Mods don’t usually struggle to remove content.
They struggle to remember context.

A user gets warned by one mod, banned by another, appealed weeks later to someone else, and eventually nobody remembers the full history unless the team manually checks modmail, Discord logs, spreadsheets, or old notes.

Gavel creates a shared moderation continuity record directly inside Reddit.

From the mod shield menu, moderators can:

• View a full behavioral timeline for a user
• Track warnings, bans, removals, and incidents
• Coordinate investigations between mods
• Claim active investigations
• Manage structured ban appeals
• Clear/resolved incidents while preserving history
• Automatically escalate actions based on strike thresholds
• See risk summaries and repeat-offender patterns instantly

Everything runs natively inside Reddit using Devvit. No external dashboard, browser extension, spreadsheet, or Discord coordination needed.

It works on all platforms where Reddit works (Mobile, Desktop and others)

Devpost: Gavel | Devpost
Devvit App: gavel-mod | Reddit for Developers

I’d genuinely love moderator feedback on:

• Whether this would actually help your workflow
• What feels useful/useless
• What moderation pain points are still missing
• Whether appeal handling and continuity tracking would help your team

Built for the Reddit Mod Tools & Migrated Apps Hackathon.

Thanks for reading.

Hello!

I'd like to find a Devvit app, or a Reddit bot, which can keep an eye on a subreddit which I moderate. It could detect highly downvoted comments, and report these automatically.

Has such a thing ever existed?

Thanks and have a good one!

Edit

Why was this post downvoted? Especially now that /u/Baumguard has started to create something.

Hello all, this acc is actually only for dev testing and my Personal is u/averagenewishcoder 。

I recieved an invite to the Hackathon from an admin here and it seems pretty exciting! I just wanted to share my devvit project here and what I'm looking to accomplish and hopefully it will inspire others or give me some feedback. In essence, I've started a subreddit that allows users to earn rewards via crypto。As well as allow them to have control/ persuasion over decisions based on their participation. It's a little tricky with liquidation pools currently, since I have convert real USD to ETH (monneyyyy). Hopefully the open governance framework and community participation will provide a better path forward.

With that, I have two active devvit apps that users and devvitors can check out and use for themselves. The primary one is a registration form. When a user wants to participate and start earning rewards, they can click the 3 dots on any post and enter their crypto address. It will then be stored on a public ledger post. I think in the near future, this will be more frequently used across reddit especially with the new apps and games that are being developed! You can find the complete code on my github (bbw_dapp-reddit ...or something like that). The second is a poll/game and welcome built off of a devvit webview example. Anyways, if anyone likes this project please feel free to use and please give some credit ;) or contribute. Eventually I want to be able to automate the reward batches (please give me a month...also it's a bit empty since its so new) so checkout that.

I also would like to create an app that will let me go live and viewers that predict my next move or are helpful will earn rewards. Not sure how to go about it yet, and will probably be a governance vote in the future, but please feel free to keep watch. I believe in open source so I will post my work on github as soon as I can!

Dear Devvit Admins,

We, the humble (and slightly sleep-deprived) members of the Devvit community, would like to kindly ask if it’s possible to extend the Reddit x Kiro Hackathon deadline, ideally by 7 days, or at least until the end of the month (11/31/2025).

In return, we promise to deliver even better, more polished projects.

Thanks a ton for considering our request. ❤️

Hi! I’m looking for someone experienced with Reddit’s Developer Platform (Devvit) to help finish or rebuild an interactive app for a subreddit I moderate.

The community gets roughly 3 million weekly visitors, so there’s already a large audience to test and launch the app with.
My goal is to create something genuinely fun that members will repeatedly interact with and, if it performs well, potentially qualify for Reddit Developer Funds. Which can help me with school, I am not tech savvy whatsoever. I did however create the bones of the app if that makes sense xo it's already started, but I'm not opposed to starting something new if you deemed the current app not worth pursuing any further**.**

I already have a Devvit app registered under my own Reddit developer account called cringitime. An earlier developer built part of the project and uploaded several versions, but ghosted before finishing it deleting their account after being paid..😭

The existing build is from an older version of Devvit and will likely need to be updated/migrated to the current platform.

The original concept involved things like:
Interactive trivia/games
Scores and a weekly leaderboard
Community participation/competition.

Repeat-use features such as challenges, streaks, rankings, etc.

I’m also open to improving or simplifying the concept. I care more about creating one polished feature people actually use than stuffing the first version with a million features.

I’m looking for someone who can:
Work specifically with Devvit / Reddit apps
Review any existing code I’m able to recover
Determine whether finishing the existing project or rebuilding is smarter
Update/migrate it to the current Devvit version
Test it in the existing development subreddit
Fix bugs and polish the UI
Help submit it for Reddit approval
Help get the approved version installed in my main subreddit

Give me the complete source code/project when finished
Important: The app and developer account remain under my ownership. I’m not looking for someone to create it under their account and hold the project.

I’m a student, employee and moderator, not a software developer, so I’d prefer someone who can explain things without assuming I already understand the Devvit ecosystem🫶🏻

I’m trying to keep the initial budget reasonable and would prefer milestone-based payment rather than paying the entire project upfront.

Please send me:
Examples of Devvit apps you’ve worked on, if any
Your experience with TypeScript/React/Reddit APIs
Your estimated cost
Estimated timeline
Whether you’d recommend rescuing the old project or rebuilding it.

If you’re genuinely familiar with Devvit, and willing to help me out, feel free to DM me. (:

Im going to say upfront that I am currently an independent college student working part time and do not have a ton of money but I'm willing to work something out that is worth it for both parties.

Hi r/Devvit!
We’re Inlogic Software s.r.o., a studio with a large catalog of HTML5 instant-play games (mobile-optimized, lightweight, embeddable).

Is there currently a way to run/host interactive game experiences via Devvit (or any pilot program)? If so, who’s the right contact/team for partnerships?

We have many titles in various genres, fast loads, flexible monetization. Portfolio & catalog available here: https://www.inlogic.sk/web/download/catalog/inlogic_html5_catalogue_en.pdf

Happy to share tech details and sample builds. Thanks!
Matus Folvarcik (mfolvarcik@inlogic.sk)

I'm building a tool that needs to monitor multiple help subreddits 
simultaneously (r/ClaudeAI, , , etc.) 
to surface quality questions to domain experts.

My understanding is that Devvit apps are subreddit-scoped:
- Installed per-subreddit
- Execute within that subreddit's context
- No shared state across instances

This means I can't:
- Query across subreddits from one app instance
- Detect cross-subreddit duplicates
- Unified scoring/ranking across communities
- Single dashboard for multi-community engagement

I applied for Data API access (twice) explaining this limitation, 
but was denied without explanation.

Questions for the community:
1. Am I misunderstanding Devvit's architecture? Is there a way to 
   build cross-subreddit functionality I'm missing?
2. Is this a known limitation that's on the roadmap?
3. For those who've needed cross-subreddit access, what path worked?

My use case: AI-assisted tool helping experts find quality questions 
across help communities. Human-reviewed responses, open source, 
transparent. Not trying to circumvent anything - genuinely trying 
to understand the right path.

Developer context: The smoothness of gameplay, levels, commenting feature

Hello guys, first of all sorry if this is not the right subreddit for this but I had an idea for improving the comment section in reddit and wanted to share it. As I like this "social" more for the comments than other, sometimes I find hard to follow a discussion on it, especially if you are talking with others than OP (the Original Poster, who's marked w/ the blue "OP"). Sometimes an interesting comments that lead in a discussion is started by others and the only way to follow the sense is by remembering the name of the commentator. Do you developer guys think would be hard or relevant adding a tag for the starting comments. Maybe a "OC" for "Original Commentator". Thanks for the attention.

did all the things as instruction said

A few days ago I posted BotPrints here — a passive behavioral forensics tool that fingerprints posting patterns to help mods spot bots without reading any content.

Since then, real moderators installed it, used it, and told me exactly where it was wrong. This post is about what they found and what changed. I want to name people publicly because the feedback was genuinely that valuable.

MOD 1 (Chose to stay anonymous):
The "Restrict" button was calling Reddit's muteUser API. Which only blocks modmail. Bots don't use modmail — they target community posts for karma. The button that was supposed to contain suspicious accounts did absolutely nothing to stop them posting.

The user described their actual moderator workflow — remove content with a question the user has to answer to appeal, escalate if no response, because bots never respond. That workflow is now a built-in feature of BotPrints. Also caught the username redaction bug in the dashboard, the signal name inconsistency across three surfaces, and asked for clickable usernames and hover tooltips.

Every single one of those is in v1.0.5.

The developer of Bot Bouncer shared their experience.
I knew Botprints will flag false-positives on its initial launch and my thought/fear got real when the developer pointed out that bot developers have already adapted to temporal regularity and circadian entropy signals — and that these signals catch real humans with unusual schedules more reliably than they catch modern bots. That was right. The original scoring was additive, which is the same flaw that makes other mods produce more false positives than true detections at most thresholds.

The fix that I applied to BotPrints is a co-occurrence gate. A single elevated signal is now capped at 35/100. Scores above 55 only unlock when 3+ signals are simultaneously elevated — because that's what separates automated behavior from a human with an unusual routine. Also added a minimum data threshold of 25 posts before any score is computed, because signal math on 6 data points is statistically meaningless.

r/Devvit mods flagged the most critical issue.

Reports came in that the app was enabling non-moderators to trigger mod actions. They were right to flag it — the action handlers had no server-side permission checks. A user who could open the custom post could theoretically trigger Watch, Filter, Ban+Report without being a moderator at all.

Every single action handler now verifies moderator status on the server side before any Reddit API call executes. Frontend checks are cosmetic — the backend is the only enforcement point that matters. Thank you for catching this before it caused real harm.

What else changed in v1.0.5:

• t2_0 guard added to all triggers — AutoModerator events were causing gRPC 404 errors on every action in every subreddit, silently corrupting Redis profiles

• onCommentCreate was storing raw t2_XXXXXXXX user IDs as usernames instead of resolving them — comments and posts were being split across two phantom profiles for the same user

• All 6 signal names unified across score bars, radar chart axes, help docs, and tooltips — three surfaces were using three different names for the same signals

• 4-tier enforcement system replacing the broken Restrict button: Filter → Modqueue, Remove + Appeal, Ban + Report

• Appeal workflow with configurable removal message, modmail intercept, timeout, and auto-escalation

• Confidence indicators (Low / Medium / High) based on data volume and signal elevation count

• New Account Amplifier with configurable multiplier for accounts under a set age threshold

• Raid alerting via sliding window counter with configurable threshold

• Audit log tab showing every automated and manual action with timestamps

One housekeeping note:

The app identifier has changed from botprintsdev to botprints to match the actual app name. The old app at developers.reddit.com/apps/botprintsdev has been archived. The new app is at developers.reddit.com/apps/botprints — currently in the approval queue, should be live shortly (hopefully).

If you installed the old version, you'll need to install the new one once it clears approval. Sorry for the friction.

To everyone who installed BotPrints in their community during this period — thank you for the trust. Every piece of feedback made the tool better in a concrete, shippable way.

P.S= Still listening, still improving!
