Frequently asked questions

How many open source architecture-diagram projects are there?

This registry tracks 3 projects tagged architecture-diagram, with 95,737 GitHub stars between them. The most-adopted is archify at 76,346 stars.

Are these architecture-diagram projects free to use?

Yes — 3 of the 3 carry an explicit open-source licence across 2 distinct licences, so there is no licence fee. Where a project also sells a hosted or enterprise version, the self-hosted path remains free.

Which architecture-diagram project should I choose?

The list above is ranked by GitHub stars, but stars measure attention rather than fit. Check three things on each card: the licence (permissive versus copyleft), the language it is written in, and the last-push date — a high-star project that has not been pushed in a year is a liability.

Are these architecture-diagram projects still maintained?

3 of the 3 were pushed in the last 90 days, and every card shows its exact last-push date so you can see the rest. Sort your shortlist by that date before committing to a migration.
