# DevX

> Cloud IDE platform that launches isolated dev containers in seconds

DevEx is a Repl-as-a-Service platform for spinning up full, containerized dev environments in the browser, aimed at people who want cloud dev environments without paying for Gitpod or E2B or building one from scratch. It's self-hostable and designed to be production-grade rather than a demo.

A Next.js frontend talks to a Go backend that provisions a Kubernetes Deployment, Service and Traefik Ingress per REPL with automatic TLS; a lightweight Go runner inside each pod exposes the file tree, terminal (PTY) and file operations over WebSockets, with S3 as the persistence layer and Redis tracking session state. An MCP server lets AI agents create, inspect and run code inside REPLs directly.
