## What it is
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
