OpenSparrow is an open-source, self-hosted admin panel framework built on PHP 8.1+, PostgreSQL, and Vanilla JS — with no npm, no Composer, no external libraries.
Visually configure everything — tables, forms, dashboards, calendars, and workflows — through an admin UI, no JSON to write by hand
20 languages supported
It’s designed for building internal business apps — CRMs, ERPs, inventory systems, task trackers — with full data ownership and no vendor lock-in
