Moving Data API Apps to the Developer Platform: migration dates and next steps

[u/boat-botany]

TL;DR: In our last update, we said we’d come back with migration dates and next steps. We know migrating takes time and effort, and we’re providing funding, technical guidance, and direct outreach and support to help. As Reddit moves to a more secure foundation, we want the useful and creative apps you've built to continue being a part of our ecosystem.

We’re sharing the timeline for moving public API apps and bots to the Developer Platform. Register now, apply for migration funding by November 30, and start planning and testing your move. Starting January 12, 2027, we’ll begin removing API access for apps and users that haven’t registered or engaged with us. Remaining public API access will end in March 2027.

Moving from registration to migration

Over 14,000 apps and bots have registered and we’re closely tracking migration of your highest-activity apps. This includes completed or near-complete migrations such as DeltaBot, MagicEyeBot, and RemindMeBot. We’re continuing to work directly with developers on their migrations and the gaps that still need attention.

There’s still time to start your migration! Register your app, review the Data API/PRAW → Devvit Migration Guide, and tell us what’s blocking you. Starting now gives you time to test and gives us time to help address migration blockers before access changes take effect.

Important dates to look out for 

The transition will happen in phases:

Date	What happens
October 31, 2026	New requests for public API access will no longer be accepted.
November 10, 2026	We share a migration progress update and deadline reminder.
November 30, 2026	Registration closes for the migration bounty program.
January 12, 2027	API access starts to close for apps and users that haven’t registered or responded to our outreach. We’ll also share a progress update and reminder.
February 23, 2027	We share another migration progress update and reminder.
March 2027	Public access will close for all remaining apps and users.

What developers should do now

1. Review the Developer Platform documentation and subscribe to r/Devvit.
2. Register your apps! Use the registration form to flag missing capabilities or blockers. You don’t need to have the migration figured out before contacting us.
3. Start planning and testing. Allow time to check that your app’s behavior meets the needs of the communities using it.

Funding and support for the move

Our $1M App Migration Program provides financial and technical support, including:

• $1,000 payments for eligible apps that successfully migrate
• Reddit Developer Funds eligible for ported apps
• Free hosting and access to developer funding programs
• Migration guides, technical resources, office hours, and direct support
• Additional support for critical moderation and community apps

Apply through the app registration form by November 30, 2026, to be considered for the migration bounty program. This deadline comes before the January API access changes, so don’t wait until then if you’re seeking funding. You can find further information in this post. 

Helping communities whose apps need an owner

If you’re a mod whose community depends on an app or bot and you don’t know who maintains it, tell us through this quick form. We’ve received over 100 submissions so far, helping us identify tools that need owners or could be replaced by existing Developer Platform apps or Reddit’s built-in tools. Keep an eye out for a message confirming we’re reviewing your submission, followed by an update in the coming weeks on available options and where gaps remain.

We’ll keep sharing progress, working through migration blockers, and supporting the developers and communities making this move. We’ll be in the comments to answer any questions.

I can't see python even being added to the road map by March like we've been begging in all these migration registration feedback forms for months, much less have the time to port it over in that time. I just took a major promotion at work and a baby on the way so my next 6 months are otherwise occupied without learning a new language and architecture and my communities will pay for it.

[u/emily_in_boots → u/fighterace00]

I literally couldn't reimpliment everything in python or any other language in 6 months of full time work, and I don't have that many hours to put in, and I can't do it in python, instead I'm stuck with the far more limited devvit which can't do what I need it to.

There is no solution here.
