LitePostLightweight API Testing

A fast, native, cross-platform alternative to Postman -- built with Tauri, Rust, and React.

Fast & Native

Built on Tauri 2.0 and Rust, LitePost launches instantly and uses a fraction of the memory of Electron-based tools. Your system resources stay free for the work that matters.

Full HTTP Support

All standard methods (GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS), multiple body types including JSON, form-data, and GraphQL, plus authentication via Basic, Bearer, API Key, and OAuth 2.0.

Collections & Environments

Organize requests into collections, define environment variables, and switch contexts in a click. Import existing workflows from cURL commands or OpenAPI specs.

Testing & Assertions

Write test scripts and assertions that run against responses automatically. Validate status codes, JSON paths, headers, and response times without leaving the app.

Streaming

First-class support for Server-Sent Events (SSE) and chunked transfer streams. Watch events arrive in real time with per-chunk timestamps and one-click cancellation.

Code Generation

Generate ready-to-use code snippets for your request in six languages -- cURL, Python, JavaScript, C#, Go, and Ruby -- and copy them to your clipboard instantly.
