From the docs, "It is strictly recommended for personal, non-production use."<p>Wow what a 180 from just a year ago when their blog said, "For companies that handle sensitive information, deploying open-source scheduling software on-premises can offer an extra layer of security. Unlike cloud services controlled by external vendors, on-prem installations let teams maintain full ownership of their infrastructure. " ¹<p>I just cannot trust a company that does a bait and switch like this.<p>¹ <a href="https://cal.com/blog/open-source-scheduling-empower-your-team-with-customizable-features" rel="nofollow">https://cal.com/blog/open-source-scheduling-empower-your-tea...</a>

Wait, I didn't even realize Cal.diy is owned by Cal.com. It seems like they're trying to get ahead of the open source community forking by doing this themselves

Cal.com has always had an open source community edition, I've been using it for some time. Is this just a rebrand of that line?

It’s curious what they said in the email they sent me about the OSS version.<p>------<p>A few important changes to note:<p>We will no longer provide public Docker images, so your team will need to build the image yourselves.<p><i>Please do not use Cal.diy — it’s not intended for enterprise use.</i>

are there notable open source forks or open source cal competitors that go for the "just keep it simple" vibe?
