MindSpark is a browser-based mind mapping app that saves your work as private JSON files in a repository you control. Connect GitHub, Gitea/Forgejo, or GitLab, and the app commits every change to a repo called mindspark-maps, giving you version history and full data ownership. It runs entirely client-side with no server in between, supports keyboard-driven editing, and lets you use OAuth or access tokens for secure, scoped access to your chosen git host.
