Marasi (مراسي) is Arabic for dockyards — places where ships are received, maintained, and dispatched. Like a dockyard for HTTP traffic, Marasi lets you intercept, inspect, modify, and extend requests as they flow through your applications.

• Desktop GUI Interface: Cross-platform desktop application built with Wails
• HTTP/HTTPS Proxy: TLS-capable proxy server with certificate management
• Request/Response Interception: Modify traffic in real-time with an intuitive interface
• Lua Extensions: Scriptable proxy behavior with built-in extensions
• Project Management: SQLite-based storage for all proxy data (requests, responses, metadata)
• Launchpad: Replay and modify HTTP requests
• Scope Management: Filter traffic with inclusion/exclusion rules
• Waypoints: Override hostnames for request routing
• Chrome Integration: Auto-configure Chrome with proxy settings
