Proxyfor
Proxyfor is a free, open-source proxy CLI for capturing and inspecting HTTP(S) and WebSocket traffic.
What Proxyfor is
Proxyfor is a free, open-source proxy CLI for capturing and inspecting HTTP(S) and WebSocket traffic. It supports forward and reverse proxy modes and provides terminal and web interfaces. Captures stream as requests and responses arrive, and users can filter and search traffic before exporting it as Markdown, cURL, or HAR. The CLI can filter HTTP(S) traffic using a regular expression matching method and URI, or by content type. Proxyfor also handles secure WebSocket traffic. HTTPS inspection requires installing Proxyfor's CA certificate on the target device; the project describes a built-in certificate installation app. It is available for Linux, macOS, and Windows, as well as web and self-hosted use. Installation options include Cargo, Docker, and downloadable desktop binaries. The documented Docker setup mounts a configuration directory and exposes port 8080. The software is available under either the MIT License or Apache License 2.0, at the user's choice.
