ZeroBox brings machine tracking, security-study references, and timed exam practice into a free browser-based workspace.

Landing page captured for the 2026-10-09 issue.

For: CTF and OSCP exam candidates
Worth noticing: Its machine directory lists 929 machines, while progress is entered manually rather than synced to Hack The Box or TryHackMe.

Field notes

The app combines a manually updated target tracker with references and practice materials, rather than syncing progress from Hack The Box or TryHackMe. Its listed materials include an eight-phase methodology guide and a machine directory of 929 entries. The FAQ says app data stays in LocalStorage and IndexedDB and can be preserved using JSON backup and restore.
