I gave all seven tools the same requirements, brand assets, and a 45-minute window. The test was not about which first draft looked flashiest. It was about structure, responsive behavior, and whether the result stayed editable.
Lovable produced the quickest first pass, Bolt left the most workable code, and v0 delivered the strongest components. None of them were ready to ship without a careful review.
The real separation appeared in round two. When I changed the pricing logic, added empty states, and tightened the mobile navigation, the three strongest products pulled well ahead.
Editor’s noteA useful tool review should make the task, time, and limitations explicit.
What this test actually tells us
First-draft speed only tells you whether a tool can start. The second revision, mobile behavior, empty states, and long-term maintenance decide whether it belongs in a real workflow.
This kind of same-brief test is genuinely useful. I would also track the time needed for a second revision, because a fast first draft does not always save time overall.
That matches my experience. The meaningful difference usually appears in responsive behavior and data states, not the first screen.
