Proxyfor vs Requestly

Proxyfor is a proxy command-line tool for capturing and inspecting HTTP, HTTPS, WebSocket, and secure WebSocket traffic. It works in forward or reverse proxy modes and offers both terminal and web interfaces. Captures stream as requests and responses arrive, allowing filtering, searching, and export to Markdown, cURL, or HAR files. The CLI can filter HTTP(S) traffic with a regular expression matching method and URI, or by MIME type. HTTPS inspection requires installing Proxyfor’s CA certificate on the target device; the project describes a built-in certificate installation app. Proxyfor runs on Linux, macOS, Windows, web, and self-hosted deployments. Installation is documented through Cargo, Docker, or downloadable binaries, including a single-file portable executable for desktop systems. Docker instructions mount a configuration directory and expose port 8080. The project is open source under either the MIT License or Apache License 2.0. GitHub lists version 0.5.0 as the latest release.
