Hey Product Hunt, I'm Daniel (). I built ZeroBox because tracking Hack The Box and TryHackMe labs across messy spreadsheets and scattered text files was driving me crazy while studying for the OSCP. I wanted a fast, keyboard-driven cockpit that keeps the entire workflow in one place without touching the cloud: - 1,000+ Preloaded Labs: HTB and TryHackMe machines organized on a Kanban board from recon to root. - Dynamic Cheatsheet: Set your attacker IP and port once; 130+ reverse shells and listener commands update automatically with 1-click copy. - 24h Exam Simulator: Realistic OSCP and CPTS scoring, countdown timer, and 1-click Markdown report exports. - 100% Private & Offline: Everything runs in your browser via IndexedDB. Zero telemetry, no account required, no backend. The project is completely free and open source on GitHub: Built this for fellow lab grinders — would love your honest feedback and feature requests.
