Microsoft Dev Proxy vs Tucano Proxy

Microsoft Dev Proxy has no write-up on Specifiction yet; its figures are above.

Tucano Proxy is a free, MIT-licensed open-source HTTP/HTTPS debugging proxy for inspecting and replaying network traffic. It runs through a configurable local MITM proxy and captures HTTP, HTTPS, and WebSocket connections. A native CLI, terminal inspector, local web interface, and desktop app provide several ways to work, with named sessions shared across the CLI, terminal UI, and web UI. The inspector presents request and response headers, timing, and bodies, with viewers for JSON, XML, HTML, raw text, hex, images, and forms. Filtering, search, capture comparison, notes, color marks, editable request replay, and exports to cURL, HAR, and Python requests support investigation. The project documents MCP integration and a coding-agent skill. Desktop installers cover macOS Apple Silicon, macOS Intel, and Windows; standalone CLI releases include macOS, Linux, and Windows. It can create a root CA and offer trust-store installation, while ordinary startup does not install certificates or change system proxy settings.
