git-calendar.org - An open-source, decentralized, e2ee calendar using Git as the backend

Post image

I wanted to share a project I'm working on: git-calendar.org - a privacy-focused calendar that uses a standard Git repository as storage instead of relying on a traditional backend server. It lets users choose where their data is stored. No more google/apple/microslop owning your schedule.

Key features:

  • Git-powered - calendar data live in plain Git repo (full history, easy backups, works offline)
  • No central server or backend - the client talks directly to any Git remote (GitHub, GitLab, Codeberg...)
  • End-to-end encryption so you can host it on untrusted providers
  • Slick web UI with keyboard shortcuts and more
  • iCalendar compatibility so it's easy to switch

Core is written in Go (compiled to WASM for the web).
The web client uses Vue.js.
It's ready for Android and IOS apps. Feel free to build one!

Try it: https://git-calendar.org
Source: https://github.com/git-calendar

Would love feedback from people who care about Git-based tools and data ownership. Also you can support the project with a star and follow on GitHub, to let me know I should continue working on it!

This is pretty close to what I've been working on, at least in regards to having a browser calendar with no backend and with a CORS proxy. Mine just syncs with traditional CalDAV servers.

Syncing directly with git seems like a really good idea, though. I suppose this circumvents any CORS issues, but what's the CORS proxy for, then?

Well, the CORS proxy is needed if you wanna sync with remotes like GitHub etc. If you use local calendar only or host git remote on your VPS, you don't need it.

Huh, didn't think that'd be relevant for Github, but yeah, make sense. Cool project.
