Reverse Api Engineer

Reverse Api Engineer, run through a command called rae, is an open source agent that turns a website into a typed API client. Instead of scraping pages with brittle selectors or guessing endpoints, it records the requests a site actually makes and generates a client from them. The vendor says the output is available in ten languages. The workflow has four steps. The user opens the command line tool and drives the browser, or lets the agent do it. The tool captures every request and response in a HAR file. The user's model then writes a typed client, and the user reviews the generated code before committing it. It works alongside coding agents the site lists as supported, including Claude Code, Cursor, GitHub Copilot and OpenCode. It is built for developers who need programmatic access to a service that offers no public API. The site states that everything runs locally, that captured traffic and generated clients never leave the machine, and that no account, server or analytics are involved. Generated files are plain source code written into the project with no SDK dependency. Installation is a single command through the uv Python tool manager. The software is MIT licensed with no fees, and no paid plans are published.
