PROJECT 001 - https://opsquest.dev/
OpsQuest — Master DevOps through hands-on challenges in real cloud environments. Tutorial hell ends here: fix real broken servers (SSH down, nginx crashed, Docker broken), earn XP and climb the leaderboard. Structured courses with a real Linux shell in the browser, plus persistent servers (Debian, Ubuntu, AlmaLinux) you can deploy, SSH into, and experiment with safely. Real VMs, not simulators—learn by doing.
