A curated awesome-list of open-source API clients that serve as alternatives to Postman and Insomnia. It catalogs web-based and desktop HTTP/gRPC clients meeting criteria of open source, 200+ stars, and 2+ contributors.

Use cases

• find an open-source alternative to Postman
• find an Insomnia alternative after the Kong acquisition
• discover desktop HTTP clients for testing REST APIs
• find a GUI client for gRPC services
• compare web-based API development tools
• find a self-hosted collaborative API client
• find offline-first or local-first API clients

When to choose

• you want a curated, quality-filtered list of open-source API clients
• you are migrating away from Postman or Insomnia
• you need to discover tools across web, desktop, and gRPC categories

When to avoid

• you need a single tool recommendation rather than a list
• you need an exhaustive directory including closed-source tools
• you need API client libraries for a specific programming language rather than GUI/interactive clients
