No JSON to write by hand.</p> <p><strong>The stack is minimalist:</strong> PHP 8.1+, PostgreSQL, Vanilla JS. <strong>No npm. No Composer. No jQuery.</strong> No external libraries on either side. Pure code only.</p> <p><strong>What you get out of the box:</strong></p> <ul> <li> <strong>Visual table builder</strong> — create columns, set types, foreign keys, validation rules — all in the UI.</li> <li> <strong>Full CRUD</strong> with inline cell editing, searchable FK columns, and subtables.</li> <li> <strong>Dashboard builder</strong> — stat cards, KPI cards, bar/pie charts, and data lists with live WHERE filters.</li> <li> <strong>Calendar view</strong> + cron-based notifications.</li> <li> <strong>Audit trail</strong> + optional record snapshots (full JSONB history of every change).</li> <li> <strong>User roles:</strong> Admin, Editor, Viewer.</li> <li> <strong>Security defaults:</strong> rate limiting, CSRF, session fingerprinting, HSTS.</li> </ul> <p><strong>LGPL v3</strong> — free for commercial use.</p> <p>Version 2.1 just released with a major UX overhaul, new modules, and security fixes. More on that in the next post.</p> <ul> <li><a href="https://opensparrow.org/" rel="noopener noreferrer">opensparrow.org</a></li> <li><a href="https://demo.opensparrow.org/login.php" rel="noopener noreferrer">Demo</a></li> <li><a href="https://github.com/wrobeltomasz/open-sparrow" rel="noopener noreferrer">github.com/wrobeltomasz/open-sparrow</a></li> </ul> <p>Feedback and contributors are very welcome!</p> php opensource webdev showdev
