24 open-source tools for Cloudflare work

We use Cloudflare constantly, so we turned the reusable parts of that work into 24 free tools. Every tool is MIT licensed, has public source, and has a one-click ZIP download with a SHA-256 checksum.

The collection covers Workers request handling, Wrangler configuration, release verification, D1 migrations and outboxes, R2 release ledgers, Email Workers, DNS and TLS cutovers, tunnels, bindings, route drift, MCP edge checks, observability policy, and account topology receipts.

What you get

These are downloadable tools, not subscriptions. You can inspect the code, run the local checks, and deploy the Worker-based tools into your own Cloudflare account. There is no sign-up or payment gate.

The first eight projects remain in their individual repositories. The other sixteen are collected in the Cloudflare Operator Tools repository with verified release downloads.

Beta boundaries

These are practical first releases. Some tools only inspect supplied snapshots; some require you to configure Cloudflare bindings and credentials in your own account. Read each README before deployment, keep permissions narrow, and test against non-production resources first.

The public catalog records the exact source commit, ZIP size, and checksum for every tool. We will keep improving the collection in public as we use it.
