Build a small internal tool that ships as one self-contained HTML file — a register, a tracker, a checklist, an audit log — using the openToolbox template. Use when someone wants a lightweight tool for tracking records that has to travel by email or USB stick and run by double-click without a server, install or database, or when they mention openToolbox by name.
