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

  • From SVG to Canvas – A new way of building interactions
    i'm building a diagramming tool (https://terrastruct.com) and still umm and ah b/t it. I'm kind of waiting for webgpu to reach 95+% browser support before switching though. If I do all the work of switching, SVG better not get gpu/hardware-acceleration support the next day. - Source: Hacker News / about 1 year ago

  • Ask HN: Visualizing software designs, especially of large systems (if at all)?
    I'm a big fan of Terrastruct (https://terrastruct.com/). They focus on building great software for visualizing complex software architecture. Their secret sauce is this idea of attention where they allow you to zoom in and out so you can get the 10 foot view or 10,000 foot view, whatever you find most useful. - Source: Hacker News / about 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: 6 months ago
