Postman is an API platform for sending HTTP, GraphQL, gRPC and WebSocket requests, organizing them in collections and automating tests. It also covers API design, documentation, mock servers, monitors and AI-assisted features, with shared workspaces for teams. Postman runs on the web and as a desktop app; the free plan is limited to a single user, and team collaboration requires a paid plan.
6 Postman alternativesPros
- Covers the API lifecycle from design and testing to docs and monitors
- Large public network of shared API collections to start from
- Collection runner and scripts automate test suites, including in CI
Cons
- Free plan is limited to one user; team collaboration requires a paid plan
- The app feels heavy and cluttered for sending a quick request
- Cloud-centric workflow is a concern for teams handling sensitive APIs

Requests live next to your code and can be versioned and reviewed with Git like any other file. It handles REST and GraphQL requests, environments, scripting and assertions, and works fully offline without an account. Paid editions add advanced Git tools, AI assistance and enterprise features.
6 Bruno alternativesPros

It tests REST, GraphQL, WebSocket, Socket.IO, MQTT and server-sent events with collections, environments, pre-request scripts and tests. Teams can share workspaces, and organizations can self-host the whole platform with Docker. A browser extension helps send requests that CORS would otherwise block.
