    I have wanted to check out your app and tried signing up to your hosted version. When signing up via GitHub i am getting a 404 from GitHub. Sign in via Google works. Later when trying to connect a Google calendar i am getting an error that 't****p***ve1@gmail.com' (censored by me, else you would probably be spammed) still needs to approve the app.

    Edit: and the timezone detection is weird. I am located in the Netherlands. It auto selected Brussels as my city. When searching there was no Amsterdam. Searching for Berlin brought up the country Denmark.

      Thank you for trying it out! The app still awaits manual approval by Google, but the calendar syncing works. Not sure why github didn't work for you, it works for me, so I'll check that.

        Sounds like it's not quite "better than Cal.com" 😉 (yet, at least)

        I use Cloudron with Gandi & Hetzner

          I couldn't reproduce the github issue, but the rest is fixed. Getting there! It is, after all, still in a beta version, fortunately, having users pointing out issues that I can fix, so it's already pretty advanced.

            @ekevu123 it is this GitHub button which generates the 404:

            Screenshot 2026-03-13 at 22.12.28.jpeg.png

            The url it links to is:
            https://github.com/login/oauth/authorize?client_id=Iv23liO6V8UT2lltQbw6&redirect_uri=https%3A%2F%2Ftymeslot.app%2Fauth%2Fgithub%2Fcallback&response_type=code&scope=user%3Aemail&state=k48T-Q4bngldlgP1Sh2dSVyUHd8QQF8g3teeNc6uII0

            @jdaviescoates everything needs to start somewhere.

            @ekevu123 A nice additional feature would be to get calendars via ews.

              Yeah, and tbh it looks like this is a really great start 🙂

                  Tymeslot - Better Meeting Scheduling than Cal.com


                  Main Page: https://tymeslot.app
                  Git: https://github.com/Tymeslot/tymeslot
                  Licence: Elastic License 2.0
                  Dockerfile: Yes
                  Demo: https://tymeslot.app

                  Summary

                  Tymeslot is a self-hosted meeting scheduling platform — a privacy-respecting alternative to Calendly and similar tools. It lets you create booking pages for others to schedule time with you, with full timezone awareness, calendar sync, and real-time availability checking.

                  Key features:

                  • CalDAV integration — syncs with Nextcloud Calendar, iCloud, Fastmail, and any standards-compliant calendar server
                  • Google Calendar sync — reads busy times and creates events directly in Google Calendar
                  • Google Meet integration — automatically generates Meet links for booked meetings
                  • SSO via OIDC/OAuth — supports Google, GitHub, and any OpenID Connect provider
                  • Multiple themes, multiple language support (English, German, French, Ukrainian)
                  • No ads, no tracking, no third-party analytics
                  • Background jobs with retry logic, rate limiting, structured logging

                  Built with Elixir/Phoenix LiveView — lightweight, concurrent, and very fast.


                  Notes

                  I'm the developer of Tymeslot, and I built Cloudron support in from the start. The cloud version is hosted on Cloudron right now. The app also supports authentication with Cloudron accounts and uses the postgres and sendmail addons.

                  What makes it a great fit for Cloudron:

                  Automatic addon integration: The app auto-detects Cloudron's built-in services. The PostgreSQL connection (CLOUDRON_POSTGRESQL_URL) is picked up automatically — no manual database config needed. Cloudron's mail relay is used for all transactional email out of the box. Cloudron's OIDC identity provider is detected automatically, adding an SSO login button without any configuration.
                  Already installable today: You can install it right now as a custom app using the Cloudron CLI. Full step-by-step instructions are at: https://tymeslot.app/docs/cloudron
                  Minimal required config: Only SECRET_KEY_BASE and PHX_HOST are needed for a working installation. Everything else is optional or auto-configured.

                  The documentation page at https://tymeslot.app/docs/cloudron walks through the full install in about 3 commands. It also covers optional extras: Google Calendar/Meet setup, GitHub OAuth, switching to an external email provider, and common troubleshooting.

                  Having it in the official Cloudron app store would make it much more discoverable for the self-hosting community — and would mean users get one-click installs and automatic updates.

                  If there are any features you are looking for, let me know! The app has been developed daily for weeks now. Please also star it on Github if you like what you see!

                  Hey, that is great! Thank you very much! I wish there were more developers like you. When you chat with other devs, do you mention Cloudron to them? What is there reaction? Have they heard of it?

                    No, they rarely have. There are so many deployment strategies out there, but I think cloudron would solve someone's problems sometimes even better.

                        @LoudLemur it's already packaged and was literally built for Cloudron. Your monster evidently needs a lot more training.

                          Haha! The "monster"! The monster should have checked if it was already published, right!

                          I would like to know from anybody involved in the packaging if the rating "moderate" was appropriate. Would any of these notes have actually saved you time, if you can remember?
