API versioning that does not require restructuring your codebase. Works with Express, Fastify, Hono, and anything shaped like middleware.

differens

A diff engine that tells you what actually happened to your code, moved, renamed, extracted, reformatted, instead of which lines changed. Algorithm-first, AI-optional, works with or without git.

Principles

How it works

Correct first, fast later

Getting the API right beats shipping quickly. Breaking changes are expensive. Edge cases get thought through before a release.

Small surface area

Each project solves one problem well. Feature creep gets refused. A small, focused library beats a sprawling framework every time.

Contribution drives ownership

Write good code, review PRs thoughtfully, help triage issues. Do that consistently and you earn maintainer access. No gatekeeping, no politics.

Come build

Star the projects that interest you. Open an issue. Submit a PR. Good work gets merged.
