Frequently asked questions
How many open source markdown-editor projects are there?
This registry tracks 12 projects tagged markdown-editor, with 31,786 GitHub stars between them. The most-adopted is genoffice at 11,557 stars.
Are these markdown-editor projects free to use?
Yes — 12 of the 12 carry an explicit open-source licence across 5 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 markdown-editor 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 markdown-editor projects still maintained?
12 of the 12 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.
