GrampsWeb is a free, open-source online genealogy platform for collaboratively building, editing, and exploring family trees, designed as a companion to the Gramps desktop software.

---

🚀 Overview

GrampsWeb solves the challenge of collaborating on genealogy research in a desktop-only world by providing a modern web app that works seamlessly with Gramps desktop data. It enables real-time editing from any device, advanced visualizations, and strict privacy controls, keeping your family history under your own hosting and away from commercial clouds.

It's built for genealogists, family historians, and ancestry enthusiasts who value open-source software and want to share trees securely with relatives or collaborators.

The Gramps project created it to bridge desktop power with web accessibility, fostering community-driven genealogy without vendor lock-in.
