Mocking up a website used to take a day. Sketching, blocking out layouts, pushing rectangles around a canvas until something looked right, then doing it again because the client hated the header.
That workload has shifted. You describe what you want, the model returns a visual, and you spend your time editing rather than building from an empty artboard. Designers, marketers, and founders who never opened Figma are now producing usable mockups, which has unsettled a market Figma held for years. The scale of that shift shows in how quickly Claude Design arrived as a direct challenge to Figma, built explicitly for people who need something visual without a design background.
We tested the platforms below on what they actually produce, not what their landing pages promise.
What Is a Web Design Mockup?
A web design mockup is a visual model of a site before anyone builds it. It shows layout, typography, color, and hierarchy so you can judge the whole thing rather than imagine it.
Think of it as the argument for a design. You move sections around, try three typefaces, test whether the call to action survives being pushed below the fold. Cheap to change at this stage. Expensive once it’s coded.
How We Evaluated These Platforms
Three criteria did most of the sorting.
Visual accuracy. Does the output look like a website, or does it look like a picture of a website? Plausible layouts, readable text rendering, UI elements that sit where UI elements belong.
Editing flexibility. A first generation is rarely the final one. Typography control, color adjustment, regional editing, and the ability to change one thing without regenerating everything separate the useful tools from the demos.
User reviews. Public feedback from people using these platforms daily, which tends to surface the friction that marketing pages leave out.
Quick Comparison
| Platform | Focus | Main strengths | Trustpilot |
| Krea.ai | AI images, posters, and UI concepts for web design | Visual assets, layout control, typography, multi-screen adaptation | 3.6 (154 reviews) |
| Framer | Building and shipping websites | Editing, CMS, code, publishing tools | 1.6 (140 reviews) |
| Midjourney | Visual concepts and imagery | Style references, aesthetic control, editing | 1.6 (372 reviews) |
Trustpilot scores reflect the time of writing. Worth reading the reviews rather than the number, since review platforms attract complaints more readily than praise for paid software.
1. Krea.ai
Krea.ai runs as an all-in-one creative suite covering AI images, video, 3D, and visual content. For web work specifically, it generates UI mockups, layouts, and posters using models with genuine text rendering, which matters more than it sounds. Most image models still produce buttons labeled in convincing gibberish.
The model lineup is the differentiator. Krea 2, Qwen, Nano Banana, Flux, Ideogram, Seedream, and Z Image all sit behind one interface, so you pick the engine that suits the job instead of fighting whichever one a platform locked you into. Nano Banana in particular built its reputation on turning flat photos into styled, product-grade renders, and that same capability transfers usefully to interface concepts.
Key features
Visual editing. Adjust color, lighting, texture, and background. Swap details, extend the canvas, change aspect ratio, apply a consistent style across a set.
Layout control. Draw regions directly onto the image to specify what goes where. You get composition control rather than hoping the model puts the nav bar at the top.
Typography. Font changes and accurate text rendering across designs, logos, posters, and graphics, which remains one of the harder problems in generative imagery.
Multi-screen adaptation. Dynamic ratio and size handling, so one concept adapts to desktop, mobile, and social formats without starting over.
What makes Krea worth choosing
It behaves less like a single generator and more like a workspace with several models available. For layout exploration specifically, being able to produce eight structural variations in the time a manual mockup takes to start changes how you work. You stop defending your first idea because it cost you three hours.
Best for: design teams, content creators, and businesses exploring layout directions for pages, campaigns, and site concepts.
2. Framer
Framer sits further down the pipeline. It builds and publishes actual websites, portfolios, landing pages, and blogs rather than stopping at the visual.
Describe what you want to the agent, and the canvas turns it into a layout you can then refine by hand. That handoff from prompt to editable canvas is the part Framer does well.
Key features
Component editing. Adjust layout, composition, typography, spacing, and color directly, without regenerating.
CMS and content. Design and content stay connected, so updating copy doesn’t mean rebuilding the page.
Code. You can extend the system with custom code where the visual editor runs out.
AI assistance beyond design. Workflow, analytics, and publishing tools sit alongside the design features.
Best for: designers, marketers, and product teams who want the mockup and the live site to be the same artifact.
3. Midjourney
Midjourney is the aesthetics option. It generates imagery and visual concepts rather than interfaces, and it’s still the strongest tool here for atmosphere.
Write a prompt, generate, upload references, adjust settings. The workflow is simple and the ceiling on visual quality is high.
Key features
Editing. Crop, extend, and upscale from standard to HD.
Visual assets. Cinematic and aesthetic imagery suitable for hero sections, backgrounds, and brand visuals.
Style references. Feed it existing work, and it’ll hold a consistent look across a set, which matters when a site needs visual coherence.
Best for: designers and marketers producing imagery and mood for a site, rather than the interface itself.
What AI Mockup Tools Still Can’t Do
Worth being honest about this, because the gap catches people out.
Generating a mockup and shipping a product are different problems. A model returns an output. The application still has to give people a sane way to inspect, edit, and reuse it, and every tweak that demands a fresh prompt leaks back the time the tool saved. That distinction between generation and the experience around it is where a lot of AI design workflows stall.
Three other limits show up repeatedly. Text rendering still fails on longer strings. Consistency across a multi-page set requires deliberate effort rather than arriving free. And accessibility, contrast ratios, focus states, and semantic structure get no attention from a model optimizing for how the image looks.
Treat the output as a strong first draft. It is not a spec.
How Do You Choose Between Them?
Depends on what you’re producing.
- If you want layout exploration and UI concepts with real control over composition and type, Krea fits.
- If you want the mockup to become a live site without a handoff, Framer.
- If you need imagery and atmosphere and you’ll build the interface elsewhere, Midjourney.
Plenty of teams run two. Generating visuals in one tool and assembling the page in another is a common enough workflow that it barely counts as a compromise.
Frequently Asked Questions
Q. Can AI replace a web designer?
Not currently. These tools accelerate exploration and remove the blank-canvas problem. Judgment about hierarchy, usability, and whether a design actually serves the business still comes from a person.
Q. Do AI mockups work for client presentations?
Yes, with editing. Output quality is high enough to present, though text rendering and small UI details usually need a pass before anyone senior sees it.
Q. Which tool handles typography best?
Krea, among these three, since text rendering sits closer to the center of what its models were built for. Midjourney remains weaker on legible text.
Q. Are these tools free?
All three operate on paid tiers with limited free access. Credit consumption during iteration is the cost most people underestimate, so check the pricing model against how much you regenerate.
Summing Up
Producing a credible web mockup no longer requires a week or a design degree. Whether you’re building for e-commerce, a local business, or a portfolio, these platforms get you to something visual fast enough to change your mind cheaply.
The right one depends on where you stop. Concepts, a finished site, or the imagery in between.
