A lightweight desktop HTTP and WebSocket client, built with Tauri 2, React 19, and TypeScript.

• HTTP requests — send requests with custom methods, headers, query params, and bodies (JSON, text, form, multipart), with full request/response history.
• WebSocket client — connect, send text/binary messages, and watch the live message log; every session is recorded with its messages.
• Saved requests — save HTTP and WebSocket requests to a flat, reorderable list for reuse.
• Environments & variables — define global and per-environment key-value variables and reference them anywhere with {{variable}} syntax.
• History — browse, inspect, search, and clear past HTTP requests and WebSocket sessions.
• Import/export — back up or share environments, variables, and saved requests as JSON.

All data (saved requests, environments, variables, history) is stored locally in a SQLite database in the app's data directory — nothing leaves your machine.

• Backend: Rust, Tauri 2, sqlx (SQLite), reqwest (HTTP), tokio-tungstenite (WebSocket)
• Frontend: React 19, TypeScript, Zustand (state), Tailwind CSS v4, CodeMirror (editors), Radix UI (primitives)
• Build tooling: Vite

• Node.js (v18+) and npm
• Rust and Cargo
• Platform dependencies for Tauri — see the Tauri prerequisites guide for your OS

Install dependencies:

npm install

Run the app in development mode (starts the Vite dev server and opens the native window):

npm run tauri dev

Type-check and build the frontend only:

npm run build

Build the full native app bundle for your platform:

npm run tauri build
