## What it is
Sparrow is an open-source, AI-powered desktop and web application for API testing, debugging, documentation, and team collaboration, positioned as a Postman alternative. Built with Svelte, Tauri, and Rust, it supports REST requests, environments, test flows, mock servers, Swagger sync, and self-hosted deployment.

## Use cases
- test rest apis without postman
- self-host an api testing tool for my team
- generate curl commands from an openapi spec
- run automated api test workflows
- mock api responses during development
- sync api collections with a live swagger url
- collaborate with teammates on api collections

## When to choose
- you want a lightweight, resource-efficient Postman alternative
- your organization requires self-hosting and data staying on your infrastructure
- you need built-in AI assistance for debugging and generating requests
- you want real-time collaboration on API collections

## When to avoid
- you rely on deep Postman/Insomnia plugin ecosystems or import complex existing workspaces
- you need only a quick CLI-based HTTP client rather than a GUI app
- you require advanced features like SAML or unlimited test flows without paying for paid tiers
- you cannot install Rust/Tauri build dependencies when building from source
