UIPalooza Pricing: Free Plan, Limits and Verdict

UI Palooza is a comparison site for AI-generated interfaces. Rather than showcasing one model's output as a portfolio piece, it runs the same brief through different models and design skills and lays the results out side by side. The site describes itself as a test of taste: compare AI-generated interfaces across models, design skills, and shared briefs. You can find it at uipalooza.ai.

If what you want to know is UIPalooza pricing, the short answer is that the site does not publish a price list, a subscription tier or a free plan. It reads as a research project with a public gallery rather than a product you buy, and the only access route mentioned is an early access email signup for people who want to compare models using their own brief. Below is what is confirmed, what is not, and how to decide whether it is worth your time.

What UI Palooza is and who it is for

Each run puts a shared brief through several AI models and design skills, then presents the outputs in a matrix layout: models sit on the rows, and the selected samples are grouped by skill variant in the columns. Runs use isolated coding agents. The Pi row uses Lunaroute, while the other rows use Claude Code or Codex.

The sample conditions are fixed parts of the experiment: Baseline A and Baseline B, an Alternative direction, and a Whacky experimental prompt. That structure is the point. You are not looking at one prompt with one answer, you are looking at how different agents and skills respond when the instructions change.

Alongside the visuals, the project records versioned ingredients for each run: skill commits, references, the model catalog, task and asset hashes, coding-agent versions, prompts and transcripts. It also runs browser interaction and accessibility checks, and keeps those separate from design judgments. Published briefs include City journal Editorial, Weekend discovery Browsing, Team inbox Work application and Forma Workshops.

Who it is for: designers, design engineers, front-end developers and product teams who want evidence about how AI models and design skills handle interface work before committing to a tool or a workflow. It is also a useful reference if you are building a comparison process of your own.

Who it is not for: anyone who wants to generate a production interface today. UI Palooza is a comparison and research site, not a builder.

UIPalooza pricing and free plan: what is actually published

As checked, nothing. The site does not publish a price, a paid tier, a credit allowance, a usage quota or a free plan, and it does not state trial terms. That is the whole pricing page situation: there is no pricing page to compare against.

Because there are no confirmed plans to list, a plan table here would be invented, so there is not one. If you are budgeting, treat UI Palooza as an unfunded research preview. There is no confirmed cheapest plan to point you to either, so the only responsible advice is to check the official site directly before you plan around anything.

What you can use openly, based on what the site publishes:

• A gallery of selected static artifacts and sanitized measurements.
• Methodology pages explaining how runs are conducted.
• A skill library so you can see which design skills are being compared against a vanilla approach.
• Stats pages covering runtime, tokens and turns.
• Example briefs across editorial, browsing, work application and workshop UI categories.
• An early access email signup to request comparing models with your own brief.

What is not open: own-brief comparison. At the time of checking, that capability is not yet available to the public, and the only route offered is the early access email signup. So the honest answer to "can I test my brief against these models?" is not yet, unless you are accepted through early access.

Free access and preview terms change often on projects like this. Confirm the current state on the official site rather than relying on any second-hand summary, including this one.

Where free access runs out

Even without a plan, there are clear ceilings on what you get:

• Briefs are fixed. You can read the published briefs, but your own brief is not supported yet.
• The gallery is curated. It contains selected static artifacts and sanitized measurements only. Original records and private experiments stay in the research workspace.
• Interactive designs run on a separate origin, so the live demos are not simply inline pages in the main site.
• Two baselines are exploratory evidence, not a statistically reliable ranking of models or skills. Do not use them to declare a winner.
• Checks measure functionality, not design taste. Accessibility and interaction checks will not tell you whether something looks good.
• Generation is not deterministic. A rerun will not reproduce the same interface exactly, so small differences between rows may mean very little.
• Money is not compared. The stats cover runtime, tokens and turns, not what a run would cost across different providers and subscription plans.

One useful scale reference: the default generation budget is 30 minutes, 120 model responses and high reasoning, with agent-specific output limits recorded per run. That describes how published runs were produced, not a limit applied to you.

How to get started

The first visit can be disorienting if you expect a normal tool. Read documentation before you scroll the gallery.

1. Read the methodology page, then the skill library, so you understand what a "skill" does relative to a vanilla setup.
2. Pick one brief you care about. Editorial and browsing briefs are easier to judge at a glance than work-application UI.
3. Read the matrix one row at a time, then one column at a time. Row order is model, column groups are skill variant and sample condition.
4. Open the desktop and mobile previews for the same artifact. Responsive behaviour is where AI-generated interfaces often fall apart.
5. Check the stats page for runtime, tokens and turns, and look at the functional and accessibility checks separately from your design opinion.
6. If you want your own brief tested, use the early access email signup and expect to wait.

Pros and cons

Strengths

• Side-by-side comparison of AI web design models and skills using the same brief, which is rarer than it should be.
• Evidence-focused design intent: versioned ingredients and transcripts are recorded per run, so results are at least traceable.
• Functional and accessibility checks are kept separate from design judgments instead of being blended into one score.
• Desktop and mobile previews are part of the published material.
• Methodology, skill library and stats pages are public, so you can inspect the process rather than trusting a summary.
• Adding design skills to compare against a vanilla baseline is part of the structure.

Weaknesses

• No pricing or plan details are available, so you cannot evaluate cost or compare tiers.
• Own-brief comparison is not open yet.
• Results are explicitly not a statistically reliable ranking, and the baselines are exploratory.
• Generation is not deterministic, which makes small differences hard to interpret.
• The gallery is limited to selected static artifacts and sanitized measurements, so you cannot audit the raw runs.
• Monetary costs are not compared across providers or subscription plans.

Privacy and data notes to check

Two things deserve a careful read before you hand anything over:

• The early access signup. If you request access with your own brief, confirm what happens to your email address, whether your brief or the resulting designs are published, and whether anything is shared with the model providers involved in a run.
• Interactive demos on a separate origin. Generated interfaces are live code from an AI model. Running them in a separate origin is a sensible isolation choice, but treat the demos as untrusted pages: do not enter real credentials, and check what a demo can access in your browser.
• Prompts and transcripts. The project saves prompts and transcripts as part of its versioned ingredients. If your brief is ever run, assume your prompt text is data worth protecting.
• Model providers. Runs use third-party coding agents and models. Their own terms apply to anything submitted, so read those before sending confidential product information.

Who should skip UI Palooza

• Anyone who needs a tool that produces shippable UI today. This is a comparison project, not a builder.
• Anyone who needs to test their own brief right now. That path is not open.
• Anyone who needs a ranked, statistically defensible answer to "which model is best at UI?" The site itself says the baselines are exploratory.
• Anyone whose procurement process requires published pricing, a licence or an SLA. None of that is confirmed.
• Anyone researching the cheapest way to generate interfaces. Cost per provider is not part of the comparison.

Alternatives to UI Palooza

If you need to produce interfaces rather than study them, these are the better-known options in the same general space:

• Bolt.new - prompt-to-app generation in the browser, aimed at building working prototypes rather than comparing models.
• Uizard - turns descriptions and sketches into editable UI mockups, useful when you want a design file to hand off.
• Visily - fast wireframing and mockup generation with collaboration features, suited to teams drafting screens together.

Each of these is a design or build tool with its own pricing model, which you should confirm on their sites. None of them publishes the kind of cross-model evidence UI Palooza does.

Verdict

UI Palooza is worth reading if your question is "how differently do AI models and design skills handle the same UI brief, and can I see the evidence?" The matrix layout, the recorded ingredients, and the separation of functional checks from taste judgments make it one of the more honest comparisons available in this category. It costs nothing to read because there is nothing to buy, and the methodology, skill library and stats pages are the parts to read first.

Do not treat it as a design tool, do not treat its two baselines as a ranking, and do not wait for it to replace a builder in your workflow. And on the specific question of UIPalooza pricing: there is no published plan to compare, so anyone quoting you a price is guessing. Check the official site for the current state, then decide whether the gallery answers the question you actually have.
