Oproxy – inspect and modify network traffic from the browser

In plain words

Oproxy is a developer tool that enables users to inspect and modify network traffic directly from their browser. It's designed for developers and QA engineers who need to debug, test, or analyze HTTP requests and responses. The tool operates as a browser-based proxy, allowing users to intercept, view, and alter network communications without requiring separate applications or complex configuration.

An open-source local proxy for developers to inspect, replay, and modify network traffic. It supports breakpoints, mock responses, map-local/remote, throttling, DNS overrides, and HAR exports for sessions. It also includes an experimental AI assistant that can help analyze traffic and create proxy rules. Built with Rust + React, MIT licensed, self-hosted, and developer-friendly.

oproxy is a local HTTP, HTTPS, and SOCKS5 proxy for inspecting, replaying, and modifying traffic. It is for developers testing browsers, CLIs, mobile apps, API clients, services, and test suites on their own machine or in a local Docker container. docker run --rm \ --name oproxy \ -p 127.0.0.1:8080:8080 \ -p 127.0.0.1:8443:8443/udp \ -e OPROXY_BIND_HOST=0.0.0.0 \ -e OPROXY_MITM_ENABLED=true \ -e OPROXY_HTTP3_ENABLED=true \ -e OPROXY_HTTP3_PORT=8443 \ -e OPROXY_ALLOW_REMOTE_ADMIN=true \ -e OPROXY_ADMIN_TOKEN= < change-me-to-a-strong-secret > \ -v oproxy-certs:/app/certs \ -v oproxy-storage:/app/storage \ ghcr.io/sauravrao637/oproxy:latest Open http://127.0.0.1:8080 and sign in with thefrom github.com

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
