In their own words
Mediator
Mediator is a free, open-source desktop proxy for debugging gRPC traffic on Linux, macOS and Windows. It can redirect requests to beta or test servers without changes to client code. When an API schema is available, it parses gRPC requests and responses and presents binary messages as a JSON tree. Schemas can come from server reflection, proto source roots compiled with protoc, or FileDescriptorSet files. Matching server rules also allow gRPC and HTTPS decoding after the client installs the root certificate generated by that Mediator installation. Certificates are available in DER and PEM formats, and another installation requires its own certificate. The proxy listens on port 8888 by default. Downloads include Windows MSI, macOS DMG, Apple Silicon macOS DMG and Linux deb packages. Setup examples cover Java, Objective-C/iOS and Go clients. The repository identifies Apache-2.0 as its license.
mitmproxy
mitmproxy is a free set of tools for inspecting and changing traffic sent through a proxy. It handles HTTP/1, HTTP/2, WebSocket, and SSL/TLS traffic, and can intercept HTTP and HTTPS requests and responses for editing. Conversations can be saved for later analysis, and users can replay client requests or recorded server responses. The project provides an interactive console, a browser-based GUI, and non-interactive terminal output through mitmproxy, mitmweb, and mitmdump. Proxy modes include regular, local capture, WireGuard, reverse, transparent, TUN, upstream, SOCKS5, and DNS. Python addons can alter behavior in response to events and expose commands. WireGuard mode can capture traffic from external devices or individual Android apps. A built-in certificate authority generates interception certificates as needed. Installation options cover Windows, macOS, Linux, PyPI, and official Docker images. The project says it does not phone home or check for updates. Documentation notes that HTTP/3 client replay is currently broken; dependencies in precompiled binaries and Docker images are fixed at release and cannot be updated in place.
