Hypr

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.

Features

• ⚡ 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.
• 🧩 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.

Download

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.

Build from source

Prerequisites

• Go 1.22+
• Node.js 18+
• Wails CLI v2 — go install github.com/wailsapp/wails/v2/cmd/wails@latest

Run wails doctor to verify your toolchain and platform dependencies.

Develop

wails dev

Live 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.)

Build a production binary

wails build

Produces a native executable in build/bin/.

Usage

1. Pick a method, enter a URL, and hit Send (or press Enter in the URL field).
2. Add request headers as key/value rows and write a request body.
3. Use the + tab button to keep multiple requests open at once.
4. Click Import cURL to paste a curl command — it fills the current tab and runs immediately.
5. Click Export to save the request/response as JSON.
