Lovable vs Bolt: I built the same app on both. One shipped.
Same brief, same afternoon, same coffee. A pros-and-cons breakdown from actually using both — not from reading their marketing pages.
I gave both tools the exact same brief: build me a habit tracker with streaks, auth, and a public share page. Same afternoon. Same me. Different results.
The brief I gave both
I copy-pasted this into both, verbatim:
A habit tracker where I can add up to 5 daily habits, mark them done each day, see a 30-day heatmap, and share a public read-only page of my current streak.
Round 1: First 30 minutes
Lovable asked me one clarifying question, then produced a working app with three routes and a schema. Colors were tasteful. It nailed the streak logic on the first try.
Bolt produced a working app faster — maybe 8 minutes to preview. But the streak counter had an off-by-one error and the public share page didn't exist. Faster ≠ better.
Round 2: The database
- Lovable spun up its integrated backend, RLS was on, share URLs worked.
- Bolt wanted me to connect Supabase, and the SQL it generated didn't match the client code. I had to fix it by hand.
Round 3: The "make it pretty" prompt
- Lovable: kept it consistent. Palette held. Typography held.
- Bolt: rewrote half the app and lost the streak logic in the process.
Where Bolt wins
- Raw speed on the first pass
- More willing to write low-level code you can inspect
- Feels closer to a coding assistant than a builder
Where Lovable wins
- Backend that just works
- Doesn't nuke unrelated files when you ask for a small change
- The published site looks like a real product, not a prototype
The verdict
If you're a developer who wants a smart pair-programmer, Bolt is more fun. If you're anyone who wants to actually ship a thing to a URL your mom can visit, Lovable wins this one. My habit tracker is live. My Bolt version is in a browser tab I keep meaning to fix.
