oproxy is an open-source local proxy server for inspecting, replaying, and modifying HTTP, HTTPS, and SOCKS5 traffic. Built in Rust with a JavaScript frontend, it supports request breakpoints, traffic rules, Lua scripting, mock responses, DNS overrides, and an AI assistant via any OpenAI-compatible model.

If you’re testing APIs and want to stay away from cloud-synced tools, Bruno is worth a look - an open-source client that stores collections as plain files on disk instead of locking them into an account.

Caido has released its latest version, 0.57.1. Built entirely in Rust, the tool continues to position itself as a compelling alternative to solutions like Burp Suite and OWASP ZAP.
