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

  • 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 / 4 months 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: 6 months ago
  • 🔥🔥 Our awesome OSS friends 😍
    Cal.com- Cal.com is a scheduling tool that helps you schedule meetings without the back-and-forth emails. - Source: dev.to / 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: 8 months ago

    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

  • GiveDirectly – Send money directly to people who need it most
    GiveDirectly is a great org that’s working in data driven experimental way to identify effective ways to donate. I’ve donated to them for years. In a similar vein is GiveWell, https://givewell.org/, who research and identify the top charities to donate to to maximize dollar impact. Their mission is to simplify giving by just telling you a very small number of orgs, removing any need for analysis or choice.... - Source: Hacker News / 7 months ago
  • Sam Bankman-Fried and the effective altruism delusion
    When I donate to http://givewell.org , I don't care about the relative value they place on arms and legs. What I care about is avoiding pseudo-charities. You know, the ones that pop up in exposé articles every now and then where most of the money goes to marketing and admin, a tiny sliver goes to the actual cause, and then a clown car pulls up full of people who try to rationalize how this is actually a good... - Source: Hacker News / 8 months ago
  • What life changing thing can you buy for less than $100?
    Givewell.org. It is a charity evaluator which uses extensive research to investigate the best, most cost-effective ways to help people in the world today. They have their Top Charities Fund which supports the highest-priority funding needs among their Top Charities. They also have their All Grants Fund to fill the highest-impact funding opportunities they can find, whether those opportunities are top charities or... Source: 12 months ago
  • Why does a 13 and 14 year old has a gun?
    You should definitely help random strangers! Do it by contributing money to stop malaria, or whatever the current top charity on http://givewell.org is. That helps far more people with far more efficiency than giving money directly to someone you pass on the street (and if you want to give money directly to people who need it, there’s also http://givedirectly.org, which does exactly that (and was also in...

  • I have a contract to be cryopreserved after my legal death for the chance of future revival AMA
    I unfortunately don't think that the 45€ per month that I spend on my cryonics contract would be able to save the poor. Also, it's not an either or. I regularly donate to charities with good rating from givewell.org. I'm not giving every possible penny I have, but my guess is that neither are you buddy. Source: about 1 year ago
