OpenSparrow – open-source admin panel builder, zero dependencies, v2.1 just dropped
Hey everyone!
I want to share a project I've been building — OpenSparrow, an open-source visual admin panel framework.
The idea: connect it to a PostgreSQL database, and you get a fully working admin panel — tables, forms, dashboards, calendar, file uploads — configured entirely through a visual /admin interface. No JSON to write by hand.
The stack is minimalist: PHP 8.1+, PostgreSQL, Vanilla JS. No npm. No Composer. No jQuery. No external libraries on either side. Pure code only.
What you get out of the box:
- Visual table builder — create columns, set types, foreign keys, validation rules — all in the UI.
- Full CRUD with inline cell editing, searchable FK columns, and subtables.
- Dashboard builder — stat cards, KPI cards, bar/pie charts, and data lists with live WHERE filters.
- Calendar view + cron-based notifications.
- Audit trail + optional record snapshots (full JSONB history of every change).
- User roles: Admin, Editor, Viewer.
- Security defaults: rate limiting, CSRF, session fingerprinting, HSTS.
LGPL v3 — free for commercial use.
Version 2.1 just released with a major UX overhaul, new modules, and security fixes. More on that in the next post.
