Has anyone else used v0.dev to build a real MVP? Would love to swap notes

Hey everyone 👋

I’ve been building products for a long time (15+ years), and I recently tried using v0.dev for the first time. Honestly didn’t expect much, but I was surprised how quickly I got something real off the ground - not just a playground UI, but a fully working fitness app with protected routes, dashboards, flow logic, the works.

It’s called The HIIT PIT — and it’s live, but that’s not why I’m posting.

I’m more curious to hear from other devs and indie makers:

• Have you tried tools like v0.dev or similar AI-based builders?

• What were the gotchas or unexpected wins?

• Would you actually ship something production-ready this way?

I still did a lot of work to stitch everything together, but it saved me a ton of time. I’m super curious how others are approaching this - especially solo builders trying to move fast.

Would love to hear your experiences or trade notes.
