ApiFreeMaN

ApiFreeMaN is a desktop client for building, sending and organising API requests. Instead of storing work in a cloud workspace, it can save each request as a readable YAML file, so request definitions live next to the code and go through normal version control and review.

Platforms: Windows · macOS and Linux listed as coming soon

Many API tools keep requests in a synced cloud workspace or in exports that are awkward to diff. That makes it harder to review changes to API calls in a pull request or keep them alongside the code they exercise.

Developers and QA engineers who want API requests versioned and reviewed like the rest of the codebase.

• Request builder for method, URL, query parameters, headers and body (JSON, plain text, XML or form-encoded text)
• Response viewer for status, headers and body
• One request per readable YAML file, organised in ordinary folders you can create, rename and delete
• Folder variables, written as {{name}}, that are filled into request URLs
• Import from OpenAPI 3, Swagger 2 and Postman collections, from a file or a URL
• Import preview that marks each item as new, matching or conflicting, then lets you create, replace or skip
• Local files by default, with no required cloud workspace

• A file format designed to be read and diffed by people: one YAML file per request with a schema version, and larger bodies stored beside it as plain JSON, XML or text files.
• Re-importing a spec without duplicating work: each imported request remembers where it came from (the OpenAPI operation, or the Postman item), so a second import can recognise it and offer to replace or skip it.
• Keeping the library safe: every file path is checked to stay inside the chosen library folder.
