Acuity Scheduling alternatives for businesses outgrowing it
The honest read: if you're leaving Acuity because your business outgrew simple scheduling โ€” you need deposits, add-ons, multiple staff and locations, and ideally a booking site you own โ€” Opencals is built for exactly that transition, and pay-as-you-go means it costs nothing until you're earning. If you're leaving for a narrower reason, match it precisely: SimplyBook.me for...

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

  • AI Almost Sold Me a Subscription I Didn't Need
    I keep coming back to what would have happened if I didn't have a strong technical understanding of how calendar technology works โ€” the difference between local and cloud calendars, what an ICS feed is, why enterprise auth blocks third-party integrations. If this was many years ago before I gained all this experience, I would have stopped at the first confident answer from my search tool, installed one of those... - Source: dev.to / 5 months ago

  • Hackathon Survival Guide: What Actually Matters
    The first category includes tools like Lovable or Base44. These are prompt-driven tools that can generate visually polished interfaces very quickly. They're great for demos that need to look impressive. However, they are usually frontend-focused. Once you need to store data, manage users, or connect real logic, things often become fragile. Backend integrationsโ€”commonly via services like Supabaseโ€”can break in ways... - Source: dev.to / 6 months ago
  • Vibe Coding: Build Apps with Words, Not Code, in 2025
    I love how AI is shaking up coding, and vibe coding seems to be the new obsession of -almost- every developer. It lets anyone, even non-coders, build apps by describing ideas in plain English. Tools like Base44, Lovable, and Cursor turn your words into working code, no syntax required. - Source: dev.to / about 1 year ago
