Mediator vs Reqable

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.

Reqable is a cross-platform HTTP development and debugging tool for API debugging, testing, and traffic analysis. It is available on Android, iOS, Linux, macOS, and Windows. Its debugging proxy supports HTTP/1.x and HTTP/2, WebSocket, HTTP, HTTPS, SOCKS4, SOCKS4a, and SOCKS5 proxies, plus TLS versions 1.1 through 1.3. API testing also supports HTTP/3 (QUIC) and Server-Sent Events. Developers can rewrite requests, set breakpoints, modify responses, and process request or response data with Python scripts. Collections can be imported from Postman, Swagger, Insomnia, Hoppscotch, ApiFox, ApiPost, RapidAPI (Paw), cURL, and HAR. Collections remain local when signed out; signing in enables cloud storage and device syncing. The mobile app can forward traffic to the desktop app through a VPN service, but omits rewrite, breakpoint, and script features. API debugging requires a CA certificate. The Community edition permits commercial use and costs nothing, with one device and 100MB of storage. Premium costs $49.90 a year for up to six devices and 1GB of storage.
