# OpenFlareStack

> A free, independent catalog of 234 open-source apps that deploy to your own Cloudflare account (Cloudflare Workers), discovered from GitHub and ranked every night by stars and recent commits. Updated 2026-10-13.

Every app listed is open source, not a fork, not archived, and has a commit in the last 12 months. Most have a "Deploy to Cloudflare" button that copies the repository into the user’s GitHub account, creates the D1 databases, KV namespaces, R2 buckets and other resources it needs, and deploys it with Workers Builds. OpenFlareStack never hosts the apps’ code; it links to each author’s repository. It is not affiliated with Cloudflare, Inc.
