I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • My Journey into Open Source: First Contributions and Lessons Learned
    Then, I came across Cal.com, a fantastic open-source project for scheduling meetings and managing tasks (super useful for productivity!). I knew the basics of Git but wasn’t quite there with forking, merging branches, and all the intricate Git processes. After some YouTube tutorials, I started to get the hang of things. 😅. - Source: dev.to / 7 months ago
  • Start your own (side) business with open-source in mind
    Cal.com is an open-source event-juggling scheduler for everyone, and is free for individuals. - Source: dev.to / about 1 year ago
  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: over 1 year ago
