A fast, cross-platform desktop REST API client — a lightweight Postman / Insomnia alternative.
Build, send, and inspect HTTP requests from a native desktop app powered by a Go engine and a React UI.
- ⚡ Native & fast — a single self-contained binary; the HTTP engine runs in Go, not a bundled browser runtime.
- 🗂️ Tabbed requests — work on multiple requests side by side.
- 🔌 WebSocket & gRPC — open live WebSocket streams or invoke gRPC methods (via server reflection); connections and output persist alongside your saved requests.
- 🧩 Header editor — manage request headers as simple key/value pairs.
- 📥 Import from cURL — paste a curl command and it's parsed, populated, and run instantly.
- 🎨 Syntax-highlighted responses — pretty-printed JSON bodies and response headers.
- 💾 Export — save a request and its response to JSON via a native file dialog.
- 🖥️ Cross-platform — macOS, Windows, and Linux.
Grab the latest build for your platform from the Releases page:
| Platform | Asset |
|---|---|
| macOS (universal) | hypr-macos-universal.zip |
| Windows (x64) | hypr-windows-amd64.zip |
| Linux (x64) | hypr-linux-amd64.tar.gz |
Note
macOS builds are ad-hoc signed. On first launch you may need to right-click → Open, or run xattr -dr com.apple.quarantine /Applications/hypr.app.
Run wails doctor to verify your toolchain and platform dependencies.
wails devLive development with Vite HMR for the frontend. A browser dev server is also available at http://localhost:34115 where you can call the Go methods from devtools. (Go changes require a restart.)
wails buildProduces a native executable in build/bin/.
- Pick a method, enter a URL, and hit Send (or press Enter in the URL field).
- Add request headers as key/value rows and write a request body.
- Use the + tab button to keep multiple requests open at once.
- Click Import cURL to paste a curl command — it fills the current tab and runs immediately.
- Click Export to save the request/response as JSON.
