Mels

A fast, private, local-first API client built for complete data ownership.

Overview

Mels is a modern, lightweight, and high-performance desktop API client built with Go, Wails v2, React, and TypeScript. It is designed around complete data ownership, local-first storage, and privacy—keeping all your API requests, collections, environment variables, sensitive tokens, and history stored strictly on your local machine without accounts, cloud lock-in, analytics, or telemetry.

Features

  • Native Desktop Performance: Powered by Go's native OS socket networking with connection pooling, keep-alive reuse, and zero CORS restrictions.
  • Clean and Minimal Interface: Built with Material UI (MUI v6) and Lucide icons, offering a focused dark obsidian workspace.
  • VS Code Monaco Editor: Integrated Monaco Editor providing syntax highlighting, formatting, and code folding for JSON, XML, HTML, and JavaScript.
  • Collection Management: Organize requests into collections and folders with instant creation, inline renaming, and zero alert dialogs.
  • Detailed Network Timing: Sub-millisecond timing breakdown including DNS Lookup, TCP Connect, TLS Handshake, Server TTFB, and Content Download.
  • JavaScript Scripting and Test Assertions: Integrated JavaScript sandbox for pre-request scripts and post-response assertions (mels.test(), mels.expect()).
  • Dynamic Environment Variables: Interpolate environment variables across URLs, headers, query parameters, and request bodies using {{variable}} syntax.
  • Persistent Storage: Local-first storage saved directly to disk (~/.mels/storage/) with single-click data management and clearing.
  • Native Import and Export: Direct collection import and export through native operating system file pickers.
  • Native Windows Frame: Clean native Windows title bar and system window controls.

Tech Stack

  • Backend: Go (Native net/http transport pooling, httptrace, local disk storage)
  • Desktop Framework: Wails v2
  • Frontend: React 18, TypeScript, Vite
  • UI Components: MUI v6, Lucide React
  • Code Editor: Monaco Editor (@monaco-editor/react)

Development Mode

Clone the repository and run live development with hot-reloading:

git clone https://github.com/username/mels.git
cd mels
wails dev

Production Build

To compile a self-contained, optimized native Windows executable:

wails build

The output binary will be created in build/bin/mels.exe.

Testing

Run the backend test suite covering HTTP execution, authentication, scripting, and concurrency:

go test -v ./...
