The same brief, three tools, one stopwatch

The pitch for AI landing page builders is compelling. Describe what you want, and the AI builds it. No coding. No design skills. No spending three days arguing with CSS about why that div won't centre.

But do they actually work? And more importantly, do they produce something you'd actually put on the internet with your name on it?

To find out, I gave the exact same brief to three AI tools and timed each one from prompt to publishable page. The brief:

"Build a landing page for a B2B SaaS product called 'OnboardFlow' that automates customer onboarding. The page needs a hero section with a headline and CTA, a features section (3 features), a testimonials section (3 testimonials), a pricing section (3 tiers), and a footer. Modern design, dark mode, blue accent colour."

Let's go.

Tool 1: Lovable

Time to first result: 47 seconds

Lovable generated a full-page React application in under a minute. The result was genuinely impressive on first look. Dark background, blue gradients, smooth scroll, responsive layout. It looked like a real SaaS landing page, not a template or a student project.

What it got right

The hero section was strong. Bold headline, clear subheading, a CTA button with hover effects, and a subtle gradient background that looked professional. The features section used a clean three-column card layout with icons. The testimonials had avatar placeholders and a nice carousel effect.

The responsive design worked out of the box. I tested on mobile, tablet, and desktop, and everything reflowed properly. This is something that manual builds often get wrong on the first pass.

What needed fixing

The copy was generic. "Streamline your onboarding process" as a headline is technically correct but deeply boring. Every SaaS landing page in existence has some variation of this headline. You'll need to rewrite all the copy, which is expected but worth noting.

The pricing section looked good but the tier structure was oddly spaced. The middle tier (the one you want people to pick) didn't stand out visually from the other two. A small CSS tweak fixed this, but it's the kind of thing a human designer would get right on the first pass.

The code

Lovable generates clean React code with Tailwind CSS. If you know React, the code is readable and maintainable. If you don't, you can still deploy it via Lovable's hosting, but you're locked into their platform for any future changes.

Time to "I'd actually use this": About 25 minutes of tweaking copy, adjusting spacing, and replacing placeholder images.

Tool 2: v0 by Vercel

Time to first result: 38 seconds

v0 is Vercel's AI tool, and it takes a code-first approach. Instead of generating a full application, it produces React components that you can copy into your own project or deploy via Vercel.

What it got right

The component quality was the highest of the three. The code was clean, well-structured, and used shadcn/ui components that are genuinely production-ready. If you're a developer, this is the most useful output because you can drop these components into an existing project without refactoring.

The design was minimal and elegant. Less flashy than Lovable's output, but more professional in a "this looks like it was built by an actual dev team" way. The spacing was perfect. The typography hierarchy was correct. Small details like focus states on buttons and proper aria labels were included.

What needed fixing

The output wasn't a complete page. v0 generated individual sections that I needed to assemble myself. The hero component, features component, pricing component, and testimonials component were all separate. Putting them together took about 10 minutes if you know what you're doing, and considerably longer if you don't.

The testimonials section was the weakest. Just text in cards with no visual interest. No avatars, no company logos, no star ratings. Functional but boring.

The code

Impeccable. TypeScript, proper component structure, accessible markup. This is the tool for developers who want a head start, not a finished product.

Time to "I'd actually use this": About 35 minutes, but that includes assembling the components and deploying. The individual components needed less editing than Lovable's output.

Tool 3: Bolt

Time to first result: 52 seconds

Bolt is the newest of the three, and it takes a full-stack approach. It doesn't just generate the frontend; it sets up the entire project structure with routing, deployment configuration, and even basic backend scaffolding if you need it.

What it got right

The full project setup is genuinely useful. While Lovable and v0 focus on the UI, Bolt gave me a complete Next.js project with proper file structure, a deployment config, and even a basic contact form that actually works. For someone who wants to go from zero to deployed landing page, this is the most complete solution.

The design was good. Not as polished as v0's output or as flashy as Lovable's, but solidly professional. The dark mode implementation was the best of the three, with proper colour tokens and consistent contrast ratios throughout.

What needed fixing

Bolt tried to do too much. The page had animations that were slightly overdone, a mobile menu that was unnecessarily complex for a single-page landing page, and a cookie consent banner that nobody asked for. Stripping out the unnecessary parts took about 15 minutes.

The features section used a grid layout that looked cramped on tablet screens. The testimonials were fine but generic. The pricing section was actually the best of the three, with a clear visual hierarchy and a highlighted "recommended" tier.

The code

Clean Next.js with Tailwind. More boilerplate than v0's output but also more complete. If you want a project you can extend (add a blog, add authentication, add a dashboard), Bolt's structure accommodates that.

Time to "I'd actually use this": About 30 minutes. More time removing things than adding them.

The comparison

| Aspect | Lovable | v0 | Bolt | |--------|---------|-----|------| | Time to first result | 47s | 38s | 52s | | Time to usable page | 25 min | 35 min | 30 min | | Design quality | 8/10 | 7/10 | 7/10 | | Code quality | 7/10 | 9/10 | 8/10 | | Completeness | Full page | Components | Full project | | Best for | Non-developers | Developers | Full-stack needs |

What about Gemini?

I also tried using Gemini to generate landing page code. The result was... educational. Gemini produced a solid HTML/CSS/JS page that worked and looked decent, but it was a single HTML file with inline styles. Fine for a quick prototype, not suitable for production.

Where Gemini actually helps is in the planning stage. Ask it to critique your landing page brief, suggest headline variations, or outline the information architecture before you feed that into one of the dedicated tools. Using Gemini to refine your brief, then Lovable or v0 to build it, is a workflow that works well.

When AI landing pages work (and when they don't)

They work for: - MVPs and proof of concept pages where speed matters more than polish - A/B testing different page structures quickly - Side projects and personal sites where budget is zero - Startup landing pages that need to go up this week, not this quarter

They don't work for: - Brand-heavy pages where every pixel needs to match a style guide - Enterprise sites where accessibility compliance must be verified by a human - Pages with complex interactions (calculators, configurators, multi-step forms) - Anything where the copy matters as much as the design (the AI-generated copy is always generic)

The verdict

If you're not technical: Lovable. It produces the most complete, deploy-ready result with the least effort.

If you're a developer: v0. The component quality is excellent and the code drops cleanly into existing projects.

If you want the full package: Bolt. More setup out of the box, including things you didn't ask for but might actually need.

All three can get you from nothing to a deployed landing page in under 30 minutes. That's genuinely remarkable. Just remember that "deployed" and "finished" are different things. Budget time for copy rewrites, image replacements, and the inevitable CSS tweaks that turn a generic AI page into something that feels like yours.
