About

API workflows should live where the code lives.

Reqbook is a local-first API workspace for teams that want API specs to be readable in pull requests, executable in CI, visible in a local browser UI, and usable by coding agents.

Why it exists

Coding agents can read source files, but they still waste context rediscovering routes, request bodies, environment variables, and expected responses. Reqbook gives them a stable contract in api-docs/.

What it is

A single Rust binary with a CLI, local web UI, markdown endpoint specs, flows, importers, validation, and agent skills for Claude Code, Cursor, Copilot, Codex, Antigravity, Windsurf, and OpenCode.

What it is not

It is not a hosted API workspace or a proprietary collection format. The source of truth is ordinary markdown committed beside your application code.
