DriftDB – an open source WebSocket backend for real-time apps▲367
Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

Over the past couple of months, I've been working on connet. At this point, it is working pretty smoothly (in what I use it for), so I wanted to share it with more people and see what they think. I know many other similar/reverse proxy solutions exist - like https://github.com/fatedier/frp, https://github.com/rapiz1/rathole, and a bunch more you can find at https://github.com/anderspitman/awesome-tunneling. However, I wanted to try and put my own little peer-to-peer twist on it. Thanks for checking it out, and sharing any…

A tool for complete WebSocket traffic control▲12
I built a Chrome extension that acts as a WebSocket proxy, allowing real-time monitoring, message simulation, and traffic interception. Think "Proxyman for WebSockets" but integrated into Chrome DevTools. Key features: Real-time WebSocket monitoring and message capture Send custom messages in both directions (client ↔ server) Block incoming/outgoing messages for testing Background monitoring (captures connections even when DevTools is closed) Why: I was debugging a WebSocket chat app and needed better tools than browser DevTools. Existing solutions required external proxies or were too…
