API testing and documentation
Postman lets developers build, test and document APIs through collections and environments. Writing tests and docs remains largely manual work.
The Git-native API client
Open-source, git-native API client for developers who want Postman's core testing features without cloud lock-in or cost.
Collaborative API design platform
A lighter, design-focused REST/GraphQL client that's long been the classic direct alternative to Postman.
Open source API development ecosystem
A free, browser-based API testing tool ideal for users who want a lightweight, no-install alternative to Postman.
Lightweight REST client for VS Code
A VS Code-embedded API client for developers who want to test APIs without leaving their editor.
All-in-one API development platform
An all-in-one API design, mock, test and documentation platform with AI features that many teams use to replace Postman entirely.
The Git-friendly desktop API client
A privacy-focused, offline-first desktop API client built for developers wary of Postman's cloud requirements.
API design and documentation with OpenAPI
The strongest non-AI, standards-based alternative for teams centered on OpenAPI spec design rather than manual request building.
