Discover Postwoman: A Free, Open‑Source API Builder to Replace Postman
Postwoman

is an open‑source, free, fast, and beautiful API builder that can serve as an alternative to Postman.

The author, a full‑stack developer, grew frustrated with Postman's paid model, lack of cURL support, and the inconvenience of maintaining separate clients for multiple operating systems, prompting the creation of a more flexible tool.

Open source

Runs online

Multi‑platform support

Multi‑device support

Accessible from anywhere

Eventually the author released Postwoman with a rich feature set:

Customizable themes

Authentication support

Parameters and request body handling

PWA capability

History tracking

WebSocket support

GraphQL support

cURL import

Native domain handling for PUT/POST

Collections for grouping requests

Proxy configuration

Docker integration

The tool’s support for cURL and GraphQL is especially appealing; importing a cURL command converts it into a standard request, though occasional parsing errors may occur.
