DrawBook: Free, local-first tool for construction payment apps
DrawBook is a free, open-source tool for small contractors to create progress payment applications without spreadsheets or expensive ERP systems. It handles schedules of values, change orders, retainage, and validation, storing all data locally in the browser. The tool is built with static HTML, CSS, and ES modules, with no backend or analytics.
Meridian48 take
A niche but well-executed developer tool that solves a real pain point for small contractors, though its reliance on localStorage means users must be diligent about backups.
