Show HN: Tymeslot – Open-source cal.com alternative built with Elixir/Phoenix

Hey HN, I'm Luka. I built Tymeslot — an open-source meeting scheduling platform.

The existing open-source scheduling tools are functional but genuinely ugly. The booking page — the thing your clients actually see — looks like a CRUD form thrown together in an afternoon. I couldn't bring myself to send people to any of them, so I built something where the booking experience feels intentional by default.

Both themes are fully customizable. Live demos here: https://tymeslot.app.

Features: Google/Outlook/CalDAV calendar sync, auto-created video rooms (Google Meet, Teams, or self-hosted MiroTalk P2P), 90+ timezones, webhooks, n8n automation, embeddable widget, SSO via OIDC.

Built on Elixir + Phoenix LiveView. Self-host via Docker, Cloudron, or Railway — or use the managed cloud (free tier, Pro at EUR 5/month). License is ELv2.

I am happy to make this the leading open-source calendar solution over time. Check Github, I develop actively. What do you expect from a calendar and scheduling tool to switch?
