RestWave 🌊

A modern, cross-platform REST API client built with Avalonia UI and .NET 9. RestWave provides an intuitive interface for testing and managing REST API requests with collection organization and advanced features.

Features

• Native Cross-Platform Performance: Built with .NET and Avalonia UI - no Electron, no browser overhead, just fast native performance on Windows, macOS, and Linux
• Fully Offline with Local Storage: Works completely offline with collections stored as files on your local file system - own your data, sync with Git, backup however you want
• Server-Sent Events (SSE) Support: Real-time streaming response handling with automatic parsing, grouping, and live updates
• Hierarchical Organization: Organize requests in nested folders that map directly to your file system structure
• Developer-Friendly: Keyboard shortcuts, request cloning, syntax highlighting, and JSON formatting for efficient workflow
• Privacy-First: No telemetry, no cloud dependencies, no data collection - your API tests stay on your machine
