ReqRes

February 2026

ReqRes is a sandboxed coding platform for backend developers who are tired of reversing linked lists. Instead, you write real Express.js code ~ JWT middleware, CRUD APIs, CORS configs and more.

Major Implementations

Isolated docker container based environment for secure sandboxed code execution
Real-time results via Server Sent Events (SSE) to show test case outcomes instantly
BullMQ-powered job queue to manage code execution tasks efficiently and scalably
Redis caching layer to store user progress, leaderboard, and frequently accessed data for quick retrieval
Secure authentication with Email/PW + Github OAuth along with full Email verfication flows using Resend
Pre-built challenges covering Auth, RESTful APIs, Middleware, Database and more
Leaderboard and progress tracking to gamify your learning journey
