proxelar

Project Overview

Proxelar is a scriptable local traffic workbench for HTTP, HTTPS, and WebSocket debugging. Capture, inspect, intercept, replay, and rewrite traffic.

Key Features

• Four interfaces: TUI, plain terminal, browser GUI, and headless REST API
• Lua scripting: on_request and on_response hooks for rewriting, blocking, short-circuiting, or mocking traffic
• Interactive intercept: Pause requests, edit method/URI/headers/body, forward, drop, or replay
• HTTPS MITM: Local CA generation, per-host certificates, and a built-in certificate install page
• Forward and reverse modes: Inspect configured clients or put Proxelar in front of a local service
• Six capture modes: forward, reverse, WireGuard, SOCKS5, DNS inspection/rewrite, and fixed-target raw UDP
• WebSocket inspection: Capture connections and browse frames by direction, opcode, and payload preview
• Portable sessions: Save/reload native captures or import/export HAR, curl, and raw HTTP files

Target Audience

• API debugging and development professionals
• Security researchers
• Developers who need traffic inspection
