Tymeslot - Better Meeting Scheduling than Cal.com
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!
