Cal.com Reviews

I've poked around a while ago at some Calendly alternatives (specifically was lo... | Hacker News
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

  • I've been trying to get some test Rinkeby ETH ("rETH") with no success for two weeks
    Atra.io create a free account, generate aWallet, set to expose private keys, fill it with Rinkeby Ether, atra will let you know when the wallet is filled, import in metamask (or use how every you want you have the keys), and you have a dev wallet for testing. Generate more than one to test from different user perspectives. Source: over 2 years 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: 7 months ago

  • Cal.com Selfhost Issue: Deploying cal.com on selfhost environment gives prisma is not defined issue.
    Has any one deployed cal.com with selfhosted environment. Is yes how would have configured prisma for the same. Source: 9 months ago
  • Open Source, EVERYTHING??
    Recently I came across a company called cal.com, it's a Calendly alternative, but the catch is the entire software is open source: https://github.com/calcom/cal.com. Source: 9 months ago
