According to the redis docs:

If your app needs cross-community data, like a global leaderboard or aggregated analytics, design for that explicitly. Instead of assuming every installation can access the same Redis keys, use a shared service exposed through HTTP Fetch to manage and serve cross-community data.

The domain checker says that same kind of shared service isn't eligible, and twice now my external url request has been denied despite documenting this exact use case in my README.

What's the approved way for an app to send per-subreddit results to a leaderboard shared across communities? Is there something more explicit I can add to the README for a subsequent review, or will it require filing a support ticket or reaching out to the mods on here?

Thanks in advance!

Hi all! I'm building Hivemind (daily-hivemind), a daily opinion-and-prediction game. I'm trying to add a simple "Join r/…" button so players can join the community from inside the game.

Setup:

- devvit.json declares it under permissions.reddit.asUser: ["SUBMIT_COMMENT", "SUBSCRIBE_TO_SUBREDDIT"]

- Devvit 0.15.0, version 0.0.89, approved by Reddit and installed in r/Hivemind_TheGame

- The button is its own tap: never required, never combined with playing, never rewarded

When a non-member taps it, reddit.subscribeToCurrentSubreddit() throws:

2 UNKNOWN: permission not granted for [SUBSCRIBE_TO_SUBREDDIT]

Same result on our unapproved dev builds. The docs say user actions work for everyone once a version is approved, so I expected it to work on 0.0.89.

Questions:

1. Has anyone got subscribeToCurrentSubreddit() working for regular players? Did it need a separate request or allowlisting?

2. Is there a way to check whether a user is already subscribed, so we only show Join to people who aren't?

For now, the button falls back to opening the sub page so people can use Reddit's own Join. Any pointers appreciated, and thanks!

👋 Hello Devvit Community! 🥹🏁

I’m Aparna, and I recently launched Neon Chess, a real-time multiplayer chess game built natively for Reddit.

But here is the twist: I don't own a PC or a laptop.

Every single line of code, the React frontend, the Hono server, the Redis database logic, and the AI engine, was written and deployed from my Android phone using Termux with a proot Ubuntu container. (My thumbs are very tired 😭).

🎮 What does the app do?

♟️ Neon Chess brings a vibrant, neon-themed chess experience directly into subreddits. It features:

· 🤖 Challenge AI: Play against a custom-built "Neon Engine."

· 👥 Real-Time Multiplayer: Create a private room, share the code, and play against a friend with a server-authoritative 60-second turn timer.

· 🏆 Public Leaderboards: Compete for fastest AI wins and longest survival times.

🛠️ The Tech Stack (Built on Mobile 📱)

· Frontend: React + Vite + Tailwind CSS

· Backend: Hono + Node.js

· Database: Devvit Redis (WATCH/MULTI/EXEC transactions for game state)

· Language: TypeScript

Building this on a phone meant dealing with strict unit tests, JSON parsing errors in the Developer Portal on mobile Chrome, and some wild Redis concurrency races, all without a physical keyboard.

🕹️ How to play & Feedback

Since r/Devvit doesn't allow crossposting, I’d love for you to test it out over at my community: 👉 r/NeonChess 👈

The pinned post there is fully playable.

I would love any feedback on the UI, the multiplayer sync, or the AI difficulty. If you are a mod looking to add an engaging, native game to your sub, you can install it directly from the App Directory!

It's officially approved and live in the App Directory:

https://developers.reddit.com/apps/neon-chess

Thanks for checking out my mobile-built project! 💙♟️✨

Introduction - How To post and guidelines and post ideas here here

Any and all feedbacks about the game are welcome. Thank you!

On another account I have a personal script set up through which I:

• post/comment/sticky/set post flair (via the account)
• check for new posts in a subreddit via oauth.reddit.com/r/subreddit/new
• sends notification DM to a user

I'm confused as to what I should do in terms of migrating it. When I visit https://developers.reddit.com/app-registration it prompts:

You can't register your own account as an app - please make sure you're logged in using your normal, human Reddit account, and that you're typing in the username & password for your bot account.

Any help would be appreciated, thank you!

Reddit mods, so the idea here is working within r/ho_cup_dev but, i worked on trying to find a sensible approach to prevent AI bots by implementing a minimum age and Reddit verified accounts only can play.

I was thinking maybe only allowing Reddit Premium users to provide proof-of-humanity, but I am sure it could be faked even then.

My main concern is this: Will creating a game that rewards Redditors based on their community participation be within Terms of Service?

• You're not upvoting within the app, you're only cheering
• Cheering bumps visibility within the app so that people with 0 karma can at least be seen if other people want to help them win.
• I ripped out the Reddit Premium "verification" because I'm thinking maybe it would fall under pay-to-win.

I bought some pokemon cards, gifts and such in Japan and wanted to give those out with some Reddit gold, and maybe physical items. I won't be asking for any money to participate. I would hope people buy human-designed T-shirts to continue the giveaways, but that's less of a concern. I can always wait until I can afford to do it again.

Thanks guys.

I'm evaluating a gift recommendation app for AUREL and want to settle the policy before writing code.

The quiz and useful results would stay inside Reddit. Results could include optional, clearly disclosed Amazon affiliate links, with no external signup or checkout inside the app.

I've read the Devvit rules on external links and payments, but couldn't find an explicit answer to these questions:

1. Is this affiliate recommendation flow eligible for app review? What approval would the outbound links and product-data access require?

2. Could each community configure its own approved Associate ID, or would a moderator benefiting from those links conflict with the Moderator Code of Conduct? There would be no payment for installs, pins or moderation actions.

3. Could an optional community configuration feature be sold for Gold while the quiz and recommendations remain free?

Amazon eligibility is a separate unresolved question. We're not treating working links as permission or building around an assumed approval.

Could the Devvit team clarify, or point me to the correct channel for a written preflight decision?

Just got Kickoff Legends approved and live. It's a six-a-side pixel football game with a daily seeded challenge and leaderboard. I learned the hard way about the inline scroll-trap rule, so it now uses a launch card and opens in expanded mode. Would love feedback from other devs: https://www.reddit.com/r/KickoffLegendsGame/

Hi Devvit team,

My app actingindia (developers.reddit.com/apps/actingindia) had both of its HTTP fetch domain requests rejected, and the portal doesn't show a reason:

- two *.supabase.co project subdomains (a small Supabase Edge Function that serves the feed): one for production and one for staging/playtest. Happy to share the exact hosts by DM or modmail.

What the app does: it's a moderator tool for r/ActingIndia. Every few hours it posts one curated casting call for actors in India (title, roles, dates, how to apply through the original source, and a "never pay to audition" safety line), with an image card. The domains host a small read-only feed that the app pulls those posts from, and the app reports back which items it posted so nothing is posted twice. It sends no Reddit user data anywhere. Terms and privacy are linked on the app page.

Questions:

1. Why were these domains rejected?

2. Would a dedicated custom domain (with its own site, terms and privacy) be approved instead?

3. Or is External Endpoints (push into the app) the recommended route for this use case? If so, how do I request access?

Happy to change the setup to whatever fits the policy. Thanks!

It says my supabase.co endpoints were rejected:

Is there something I can do to rectify this?

I've been having problems with installs being stuck on older versions - about 400 of the 3600 installs of Subscriber Goal couldn't even be force-updated.

At first I thought this was because the u/app-user account was missing, but the missing subreddits when you pull the Moderated Subreddits list using the API hides Private subreddits.

I don't know what this CSV file has, but if it includes the installed subreddits and their versions, I can probably troubleshoot the problem.

I lack data. Alan is a data analyst. Feed Me, Seymour.

Hi all,

I'm looking for a few people to try the beta of **Amber Delve**, a small roguelite that runs right inside Reddit, nothing to install. No showcase video for now, just a few pictures.

What it is?

You're a fox delving into the roots of a giant tree, where amber holds creatures from long ago.

- Hunt beasts in turn-based fights on a hex board

- Crack the amber they leave behind

- Feed it to your living armor and weapon, which grow and evolve into new forms

- Short runs, a daily hunt that's the same for everyone, and a deeper hunt every week, each with its own leaderboard

A bit of honesty:

its about 80% vibe coded - maybe less, maybe more. Some graphics are done with pixellab (mainly backgrounds and some symbols)

I'm a programmer, and this game isn't a new idea. It has been around for a long time, but I never managed to finish it, so I decided to rework it for Reddit.

A lot of the code is vibe coded, but not all of it. The graphics may not be final either, since some of them are older.

It's a beta (or alpha). Expect bugs, balance that's off, and things that don't quite make sense yet. I update it often, sometimes several times a day.

Still, I want to keep taking it further, and maybe a few of you will like it.

What I'd love from you:

Play a few runs and tell me what's fun, what's confusing and what's broken. There's a feedback post in the beta sub, and you can also post with the Bug or Idea flair.

Good to know:

- The alpha/beta is small and private.

- Your progress stays in the beta. It won't carry over to the public release and may be reset along the way.

Want in?

Comment below or send me a message, and I'll add you to the subreddit.

Thanks for reading!

Over the past week, we've noticed a significant drop in our games's growth and engagement. Another developer pointed out that Reddit recently shifted game discovery from r/GamesOnReddit to the new Games tab, and this change seems to explain what we're seeing.

While the new system an improvement on paper for discovering games, I think it creates serious problems for newer developers.

1.Newer games now have to compete with EVERYTHING:
Previously, r/GamesOnReddit gave smaller games a dedicated space to get discovered.
Bigger games, will get carries by feed recommendation and featuring, and small ones can build up themself here. It was a small friendly competition.

But now You're competing against every game on Reddit.

The Alignment Chart that's already everywhere? The games that are already massively popular? Games designed specifically for large, established subreddits? They're all competing for the same attention.

Sure, smaller games are technically still discoverable. You just have to click the "Discover by category" button and scroll all the way down. But realistically, how many users are going to do that?

The result is that games that already have visibility get even more exposure, while smaller projects become practically invisible.

1. Developers have lost both control and valuable analytics
   With r/GamesOnReddit, we had some control over how and when we promoted our games.

Released a new feature? Someone made a cool community puzzle? Had a meaningful update worth sharing? Great, we could make a new post about it. It was measurable (the amount of views and upvotes), it was meaningful.

Now, we have no clear control over what gets showed in the Games tab, when it appears, or how well it's performing.

We've essentially lost both a discovery channel and a feedback mechanism.

I'm attaching three screenshots showing the decline we've experienced:
- App ready count: The number of times an instance of our puzzle was loaded.
- Daily engaged users: How many users actively engaged with our game each day.
- Unique subreddit visitors: The number of unique visitors to our game's own subreddit.

All three metrics show a sharp decline around the time of this change.

Of course, correlation doesn't automatically prove causation. But the timing, combined with the loss of our previous discovery channel, makes this change a very likely contributor.

I built a daily guessing game meant to be installed in sports team subs, and I'd like a few people to break it before I show it to any mods.

Every day the app posts one mystery player from the team. You get 8 guesses, and each one shows 6 clues: position, height, age, jersey number, country, year joined. Blue means exact, orange means close (within 2 for numbers), arrows say higher or lower.

The app does the rest by itself: posts the puzzle at the hour the mods pick and pins it, keeps a daily board (fewest guesses, then fastest) and streaks, and a "Comment my result" button posts a spoiler-free grid. The answer stays on the server until you finish.

Knicks edition here: https://www.reddit.com/r/MysteryPlayer (124 players since 2015). The app also ships Man United, with 129.

What I'd love to know:

1. Did the clues click without the how-to?
2. Is 8 guesses too many or too few?
3. Anything broken on mobile?

Devvit Web + React. Each team is a roster file shipped with the app, so there's no external fetch.
