I was working on a new website for https://flatcal.com. With Flatcal I'm trying[1] to scratch my own itch when sharing busy status with .ics calendars. My life is organized between corporate (Outlook), private (GCal) and freelance (various) calendars. Finding a freebusy slot or sharing my accessibility is not easy, and sending someone multiple links makes a little sense. So I figured that I will build calendar processing pipeline that will merge, filter, anonymize, inject, rewrite (etc) calendar events can solve this problem for me. And having all of them merged into a single .ics file is way easier to share, and safer too.
