How apps get on the list
No hand-picking and no paid spots. A GitHub Action rebuilds the list every night.
- 1
Found
We search every public README on GitHub for a Deploy to Cloudflare button, and add hand-picked apps and submissions.
- 2
Checked
Forks, archived repos, Deploy-button copies, stale projects and anything without an open licence drop out.
- 3
Read
We read the README and wrangler config, keep finished apps (not starters or demos) and turn each binding into a tile.
- 4
Ranked
Stars, recent commits and releases set the order. Stars and dates refresh every night.
The tiles show what an app creates in your Cloudflare account:
- D1KVHdData
- R2ImStorage
- DOQWfLive state
- AIBrAI
- CrSchedules
- EmEmail
- AEMetrics
Questions people ask
What is OpenFlareStack?
A free catalog of 268 open-source apps you can run on your own Cloudflare account, such as self-hosted alternatives to Semrush, Gmail, WordPress and Notion AI. A GitHub Action finds new apps every night and ranks them by stars and recent commits.
How do I self-host an app on Cloudflare?
Open an app and press Deploy to Cloudflare. Cloudflare copies the repository into your GitHub account, creates the databases and storage it needs (like D1, KV or R2) and deploys it to Workers. Apps without a Deploy button have install steps in their README.
Do I need a server?
No. The apps run on Cloudflare Workers, so there is no server, container or VPS to look after. Your data stays in your own Cloudflare account.
Is it free?
The apps are open source and free to use. Many small apps fit inside Cloudflare’s free plan. Busy apps can need a paid Workers plan, so check the app’s README and Cloudflare’s current pricing.
How do I keep a deployed app up to date?
The Deploy button makes a copy, not a fork, so updates are not automatic. Every app page has a three-line snippet that pulls the latest version from the original repository and redeploys it.
How are apps ranked?
By GitHub stars, how recently the code changed, and whether there is a published release. Forks, archived projects, repos without an open-source licence and starter templates are left out.
How do I get my app listed?
Use the checker below. It runs the same checks as the nightly scan, and if your repo passes it opens a pre-filled GitHub issue. Apps with a Deploy to Cloudflare button in their README are found automatically.
Is OpenFlareStack part of Cloudflare?
No. It is an independent project. Every app belongs to its authors and installs from their own repository.
Submit your repo
Paste a GitHub link and we check it right here, in the same order the nightly scan does. If it passes you'll see your listing before you send it.
- 1A public repository
Not a fork and not archived.
- 2A README at the root Required
It's the first thing we read. No README means no listing.
- 3A Deploy to Cloudflare button, or a wrangler config
We look for the button in your README first. If it isn't there we read
wrangler.jsonc,wrangler.jsonorwrangler.tomlfrom the root and build the Deploy link for you. - 4An open-source licence
MIT, Apache, GPL and the like, so people know they're allowed to run it.
