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!

Tymeslot log shows that email was sent successful, but cloudron logs show now Email. How can I support you to find the bug?

Another bug: when using Mirotalk SFU creating a room exits with an error after 5 retries.

You can take LAMP app repository as an example.
https://git.cloudron.io/packages/lamp-app

The repository for Tymeslot should only include what is needed to build the app.
One important part is the test/test.js which includes the life-cycle tests which are checked whenever an app update is available.
When the basic app is in the repository I can further assist with tests and other things.

You already did most of the work in your GitHub, but that includes everything.
The Cloudron GitLab repository should only have what is really needed to build the app.

Hello @ekevu123
We have created this repository for you https://git.cloudron.io/playground/tymeslot.
Can you create the Cloudron app in this repo?
If you need any information, help or permissions. Please let me know.

Can you maybe walk me through the process in general, like everything basically? I don't really have any context about the implications of publishing the app in the cloudron app store. It's my first 🙂

  1. cool 🙂 looking forward to it!
  2. Changing the text itself would be great - but isn't as important as 1 for me - as I can't use it productively for my home office days 🙂

Regarding customising availability, I'll note this for the nearest future. Regarding localisation, do you want to get e-mails translated? The booking experience is already supposed to be international for the user booking (with EN/DE/FR/IT/UK supported), but you can't change the text. Would you like to change the text, are you looking for a new language or would you like to see the whole app localised? The latter will happen, but not yet.

2 thinhgs:
Available days - it would be perfect if this could be set individually per meeting type - as this depends of the work location and individual factors.
So my availibility is different for online meetings (home office) and in person meetings (I'm at the office)
It woould be good, if we could customize the mails (localization).
Thanks for the great work!

@ekevu123 Hi. Caldav via SoGo and mailbox.org
The calendars do appear when I enter my login credentials, but the appointments aren't syncing. at least with one account - the other only sync partially.
"Some calendars have never been synced" - refreh doenst help.

Okay, I got it, the next update will support mailbox.org as well, but this might require 2-3 days to implement!
From what I am seeing, you would want to create an app-specific password in mailbox.org, though, as Sogo acts as another frontend, but correct me if I am wrong here.

I'll create accounts and see if I can test it and see what happens!

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.

Thank you, I will look into that!

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.

I didn't know people use it usually like that, will do!

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