The best Postman alternative in the browser: open source, free for personal use and self-hostable, but shared team workspaces on its cloud are paid and browser requests to local APIs need its extension or proxy.
What it is
Hoppscotch is an MIT-licensed API client for REST, GraphQL and realtime protocols (WebSocket, SSE, Socket.IO, MQTT) that runs in any browser at hoppscotch.io, as a desktop app, as a CLI for CI, or self-hosted on your own infrastructure. It has collections, environments, pre-request scripts and tests, a collection runner and code snippets, and imports Postman collections. On Hoppscotch Cloud the Free plan covers a personal workspace; Business is $6 per user a month billed yearly and adds team workspaces with real-time collaboration, shared collections and environments, published API documentation, API mocking and an admin dashboard; Enterprise is $11 per user a month billed yearly with SAML SSO and OpenID Connect, SCIM provisioning, role-based access, audit logs and AI agent features.

Best for
- Quick API testing in the browser with nothing to install
- Teams that want to self-host their API client
- Developers who want an open-source Postman replacement
What we like
- Open source (MIT), free for personal use and self-hostable
- Runs in the browser, on the desktop and in CI through its CLI
- Team workspaces cost $6 per user a month billed yearly, under a third of Postman Team
What to watch
- Shared team workspaces, published docs and mocks on its cloud need the paid Business plan
- In the browser, requests to localhost or APIs without CORS need the Hoppscotch browser extension, a proxy or the desktop app
- SSO, SCIM and audit logs only on Enterprise
- Postman scripts need manual review after import
