If you've ever wanted to practice DSA problems with a real person but couldn't afford paid platforms, I built something for you. PeerCode is a free peer-to-peer mock interview platform where you can:

Practice DSA problems with another person in real time Write and run code together in a shared editor Do video + audio calls without leaving the platform

No paywall. Just open and practice. Built with React, Node.js, Socket.io, WebRTC, PostgreSQL. Try it out: peercode.live Feedback welcome.
