    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!

    @ekevu123 Cool app, toying with it right now. One observation:

    • when trying to connect to my nextcloud calendar, it connects and recognizes the different calendars but when I press Add integration, it returns Base url Must be a valid HTTP or HTTPS URL (e.g., https://example.com) nonetheless.

          Thanks for adding the community version!
          I installed tymeslot. How can I deactivate the user login? I tried adding a .env with

          REGISTRATION_ENABLED=false
          PASSWORD_AUTH_ENABLED=false
          

          but the login/registration for external users is still possible. Could somebody give me a hint whats wrong here?

            Try using the Cloudron CLI to set these!

                Hello @ekevu123

                Since not everyone is comfortable using the cloudron cli maybe you could add a .env.sh handler like we do with many packages.
                Many Cloudron users also know this flow from us, guess that is why @enerch tried that approach first.

                    Which Caldav calendar are you using? And how do you assume it doesn't sync them?

                        Hello @ekevu123
                        If you'd like some examples for how we do that, you could check out the start.sh of the mirotalk app or the start.sh form the Kutt URL shortener app to just name two examples.


                        One small note on that topic.
                        When merging env files together like we sometimes do, ensure that a newline is present otherwise it could end up appended to the last string.
                        See: https://git.cloudron.io/packages/twenty-app/-/merge_requests/6/diffs

                        Without the linked diff, if a new line in /app/data/env is missing the string gets appended.
                        So if your last line in /app/data/env is STORAGE_LOCAL_PATH=/app/data/local-storage and it gets appended to /run/twenty-server/.env it results in:

                        STORAGE_LOCAL_PATH=/app/data/local-storageIS_CONFIG_VARIABLES_IN_DB_ENABLED=false
                        

                        344fa16c-dce1-47e4-8d85-2ac80f4b916f-image.jpeg
                        so to ensure this never happens the adding a newline after the cat >> /run/twenty-server/.env <<EOT is enough.
