Three small Cloudflare tools, now open source
Download Worker Request Kit, Wrangler Config Doctor and Cloudflare Release Proof: three free v0.1 betas with public source.
Start with one small job.
We use Cloudflare across our work. We’re turning some recurring tasks into small utilities other people can pick up without needing our setup. The first three are available now.
Worker Request Kit
Five request helpers: bounded JSON, CORS, idempotency keys, honeypots and keyed identity hashing. No persistent deduplication, rate limiter or hosted service.
Cloudflare Workers Web APIs; Node.js 22.13+ for tests.
Wrangler Config Doctor
Catch eight common Wrangler configuration problems offline, from a CLI or local MCP client. Advisory checks, not full Wrangler validation. No account token or deployment.
Node.js 22.13+; Windows untested.
Cloudflare Release Proof
Create release manifests and verify that local folders or public HTTPS files contain the expected bytes. Point-in-time byte checks, not deployment ownership or hardened hosted SSRF protection.
Node.js 22.13+; Windows execution untested.
Small betas, with room to improve.
Each release includes a checksum and a working example. The two command-line tools also expose local, read-only MCP tools. Worker Request Kit is a library you import directly into a Worker.
These releases cover the jobs described above. They are not hosted services, complete Cloudflare account managers or claims of production readiness. Start with the included examples and tell us what gets in your way through the public repositories.
No sign-up or payment is required. Original code is MIT licensed; bundled dependency notices are included. Valen Systems is independent of Cloudflare.
