## What it is
CocoaRestClient is a free, native macOS application for testing and debugging HTTP/REST endpoints, built in Objective-C. It offers a lightweight GUI for making requests with headers, auth, and bodies, and pretty-prints JSON, XML, and MsgPack responses.

## Use cases
- test REST API endpoints on macOS
- pretty print JSON and XML API responses
- save and reuse HTTP requests with headers and bodies
- send POST and PUT requests with form data or file uploads
- compare two API responses with a unified diff
- test endpoints with basic or digest authentication

## When to choose
- you want a lightweight native Mac GUI alternative to curl for API testing
- you need to save and organize frequently used HTTP requests
- you want pretty-printed JSON/XML responses and response latency reporting

## When to avoid
- you need a cross-platform tool that runs on Linux or Windows
- you need scripted or automated API testing in CI
- you need advanced features like GraphQL, gRPC, or environment variables found in tools like Postman or Insomnia
