Quick one on the code side. Did any of the five wire the line chart and traffic charts to an actual chart library or did they mostly come back as static SVG with hardcoded numbers? For a dashboard that feels like the bit that decides how much rebuild is left more than spacing or typography.
I focused more on the overall frontend implementation in this test, so honestly, I didn’t go deep enough into whether each chart was backed by a real charting library versus being rendered as static/hardcoded data.
And you're right; for a dashboard, that can make a huge difference in how much rebuilding is left.
thanks for sharing!
Welcome! 🙌🏻
Same input, same prompt, paired - that's the right instrument, and it already beats every feature-list comparison out there. Two additions would make the ranking hold weight beyond one afternoon: run each tool 3× on the same input (single runs are one draw from a noisy distribution - I've watched a published "winner" reproduce zero times in five reruns, in a different domain), and put two or three mechanical checks next to the eye - lint error count, an axe accessibility pass, bundle size. Your best sentence is the criterion most comparisons skip entirely: what matters is how much work remains after the first generation. That number, measured, would make this the reference post for the category.
I agree. A single run can definitely capture a lucky or unlucky generation, so testing each tool multiple times would make the comparison more reliable.
I also like the idea of pairing the visual evaluation with mechanical checks like lint errors, accessibility, and bundle size. That would give the comparison a more complete picture beyond what looks good at first glance.
Thanks for the suggestions! You’ve definitely given me some ideas for a follow-up test.
One concrete thing for the follow-up, since three runs each is the plan: publish the spread, not the average. For non-deterministic tools the variance is a finding — a tool that lands 8/10, 8/10, 8/10 and one that lands 10/10, 7/10, 5/10 are not the same product, even with the same mean, and the second one is far riskier to build a workflow on. Same idea as your "how much work remains after the first generation", just applied to reliability instead of quality.
This is awesome! 👏🏻 Thank you!
As @aidasaid said, reading the docs doesn't tell much. You can know the real performance of a tool only when you try it. As a developer, this kind of breakdown is very helpful for me.
You're welcome! 🙌🏻 Glad you found it helpful, and I hope this article saves you some time of reading documents 😅
Sure, it does 😄
Cool 😄
This is really straightforward. Making AI design to code tools face the same challenge with the same prompt is what we need to see. This will save me a lot of time testing tools and reading their docs to see which one I need to choose 😅
Huge thanks!
You're welcome! 🙌🏻 Glad you found something helpful here 😄
You're right; making AI tools face the same challenge and giving them the same prompt is much more useful than reading their docs.
Really enjoyed this comparison, Hadil. Using the exact same dashboard and prompt for all five tools makes the results much more meaningful than simply comparing feature lists.
I especially liked that you looked beyond the visual output and also evaluated the generated code, since a polished UI is only useful if the implementation is actually practical to work with.
The point about visual quality and code quality being two different things really stood out to me. It is easy to focus on the screenshots, but the amount of work required after the first generation is what really determines whether a tool saves time in a real project.
Great work on the testing and breakdown. This is a much more useful way to evaluate these tools than relying on demos alone.
Thank you so much! That was what I wanted to get out of the comparison. It’s easy to be impressed by a polished screenshot, but once you have to work with the generated code, the picture can change quickly.
I’m really glad the point about the work left after the first generation stood out to you. For me, that’s ultimately where these tools prove their real value.
Solid comparison. When refactoring an older dashboard layout like this, clean Tailwind/CSS tokens and sensible prop extraction save the most time. Which tool felt closest to a real production-ready handoff rather than just a static prototype export?
I’d say Flowstep came closest in this particular test. That said, I wouldn’t call any of the five a true production-ready handoff straight out of the box. There’s still some cleanup and refinement needed, especially once you start thinking about reusable components, real data, responsiveness, and the rest of a production codebase.
the code quality dimension is the one most comparison posts skip. we put v0 and Lovable through an internal dashboard rewrite a few months back and the gap in generated code quality was the deciding factor, not which one looked better in the screenshot.
v0's Tailwind output was cleaner but it inlined magic numbers everywhere instead of pulling from a token layer. maintenance on anything it generated required a full cleanup pass just to make it predictable.
did Flowstep's clean code output actually use a consistent token system, or was it just better organized hardcoded values?
I agree. The maintenance side tells you much more than the screenshot.
For Flowstep, I found the code better organized and easier to work with, but I wouldn’t say it fully implemented a proper token system in the way you’d expect from a mature production design system. There were still hardcoded values that would need some cleanup and standardization.
Have you tried using eg. Claude, but with a frontend design skills file?
No, I haven’t tried that yet! I tested the five tools directly for this comparison, without adding a separate frontend design skills file to the workflow. But that’s an interesting approach.
Anthropic and Figma built pretty comprehensive skills specifically to mitigate the "Cyberpunk Glassmorphism" trend all AI's seem to lean towards, worth a shot!
Wow, thanks for sharing this. This is educative..
Welcome! 🙌🏻 Glad you found it helpful.
One gap in tests like this. Dashboards are rarely just one screen, they scroll, and these tools mostly work off whatever image you hand them, so if the capture misses half the page the redesign misses it too. I built a free tool called SlimSnap.ai for exactly this after getting tired of stitching screenshots by hand.
slimsnap.ai
Using the same intentionally dated interface is a strong test design because it exposes whether a tool can infer hierarchy rather than merely reproduce pixels. I would also compare the cost of making one real product change after export.
