Probe vs Reqable

Probe is a local HTTP/HTTPS proxy and API client for examining application traffic, editing requests and responses, creating mocks, and automating requests. It can capture traffic from phones, simulators, desktop apps, and terminal clients, then show headers, bodies, and timing. Breakpoints let users pause a request or response, change its headers or body, and continue or abort it. Map Local serves a local file or inline body for matching URLs; Map Remote forwards them to another host. Visual flows can chain requests, extract values, check results, branch, and loop, and run in the app, through REST API or MCP, or with a headless CLI. The API client supports HTTP and GraphQL, collections, environments, authentication, and history. It imports cURL or Postman and exports to Postman v2.1. Probe also includes an MCP server for compatible clients and file browsing and transfers over SFTP, FTP/FTPS, S3, and WebDAV. It is available for Android, iOS, macOS, Windows, and API use. The free plan costs nothing.

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.
