I need to add booking to my website. I stumbled upon cal.com which seemed great. However I’ve run into 2 issues.
My current options for calendars are Protonmail and cpanel/webmail/roundcube.
cal.com doesn’t really work with either of these. For proton its mostly on proton’s side, their calendars are read-only externally + a bit buggy: https://github.com/calcom/cal.com/issues/5756
Roundcube uses caldav, and cal.com’s support is still in beta with most caldev’s being unsupported: https://github.com/calcom/cal.com/issues/3457
Roundcube got me the farthest but the booking emails just don’t get sent and the calendar event pops up maybe an hour later + there’s 75% the booking just doesn’t work. I was told this was the calendars fault 😂.
SO
Are there any selfhosted calendar implementations that support ics feed, external viewing ,etc etc that I can throw on a standard webserver?
Or are there any better foss booking systems?
I just need to book clients and connect it back to a working calendar that’s not locked to a desktop. I thought this would be a solved problem in 2026…
I’m not trying to pay for yet ANOTHER software on top of business mail, and a webserver.
Thanks.
never hurts to learn.
Took me a while to get back to this. I got a bit sick over the weekend. Anyway, the opensource scheduling software is not too great. I am a little surprised by it as there are a few commercial options or opensource options that lock certain features behind a paywall even when selfhosting, like cal.com.
Cal.com is the only software that provides the feature set I need, but they charge about as much per user as Zoom does and it pisses me off that it’s so expensive to have a shared calendar so my clients will simply book a time and date and have round robin logic applied to who the client gets assigned to.
Because of this, I am slowly working on building my own scheduling system that I will selfhost. I am mostly vibecoding it as I am too busy running a small company to dedicate time to coding it properly, but that is some tech I can easily test for functionality and fix down the line when there is more time or money.
simplybook.me is another service I came across, but they charge you based on how many features you enable, and you basically can’t use their system for scheduling without adding on a bunch of features. Once your trial ends, you can’t turn off the features and go back to the free version without signing up for a pro account or whatever they call it.
