Design Arena sends one prompt to several AI models, hides which model made each result, and turns your head-to-head votes into public leaderboards for websites, images, slides, video, speech and more.

Design Arena is a web-based AI design benchmark: you submit one creative prompt, several AI models answer it, and your blind votes decide which output wins. Its terms describe it as a benchmarking platform for evaluating and ranking machine learning models through AI-generated design outputs, offered by Arcada Labs Incorporated.
The same session doubles as a creation tool. Users describe what they want to make, from a website or game to an image, video, presentation or app, and see how the top models render that idea side by side.
Scale figures come from two different places. The homepage says millions of people across 190+ countries use Design Arena to discover and compare models. An independent news report from August 2026 put the figure at 5.3 million people worldwide.
The name is easy to confuse with Arena (formerly LMArena and Chatbot Arena), a public web platform that evaluates large language models. Design Arena's own terms name Arcada Labs Incorporated as the provider, and its focus is visual and interactive output rather than chat replies.
Each voting session draws four models from the active pool plus one backup, and every model receives the identical prompt. Model identities remain hidden throughout evaluation to prevent brand bias. Outputs are also revealed at the same moment so faster models gain no edge, a rule the methodology notes say may change later.
The session is structured as a small bracket rather than a single A-versus-B pick. Two pairs are judged first, then winners and losers meet, and each of the five battles produces one vote that feeds both win rates and the rating model. The result is a full 1st-to-4th ordering from one prompt.
In the main Model Arena, a model can take part only if it accepts a text input and returns a single-file HTML/JS/CSS code file. System prompts are kept constant across providers to minimize bias, so every model works from the same instructions.
Rankings are calculated with the Bradley-Terry model, a statistical method built for pairwise comparison data, and shown as Elo-style ratings. Each model's estimated strength is converted with Rating = 400 × log₁₀(strength). The margin of error uses an approximate 95% Wilson score confidence interval. Every pairwise vote is weighted equally, with no filtering or editorial adjustment. The leaderboard is updated with live results every two hours, and models with fewer than 50 votes carry a "new" tag to signal that their position may still move.
The roster changes often, which is part of what makes Design Arena useful as an AI model leaderboard. On September 22, 2026 the changelog recorded claude-opus-5-5, gpt-6-sol and gpt-6-luna as added. Removals come with short reasons, such as a model that was consistently bottom-ranked across categories.
It is not built for anyone under 18: the terms allow use only by people 18 or older who can form a binding contract.
No standalone pricing page was found among the pages checked, and /pricing returned not found. The terms state that there are no fees for use of the Services unless otherwise set forth, for example for certain limited additional features. The paid rules below come from the account and billing interface text.
| Access path | What it covers | Published cost |
|---|---|---|
| Free tier | Everyday prompting and voting within usage limits | No fee under the terms |
| Prepaid credits | Usage beyond the free tier, plus Pro benefits | Top-ups from $5 to $100 |
| Premium mode | Top-ranked models by Elo for a generation | Actual cost per generation |
| Leaderboard API | Programmatic ranking data | Free, with attribution |
Credits work as a prepaid balance and are deducted only when you go past your free tier limits. Top-ups range from $5 to $100 per purchase. Free usage has per-category caps on top of a shared daily limit, and those limits vary with prompt complexity, so the number of free generations is not a fixed figure. One Pro benefit is video length: up to 15 seconds versus 5 seconds on the free tier.
Premium mode picks the best models by Elo for that generation and charges the actual cost per generation. Per-type prices load inside the account area and were not shown on the pages checked.
Category availability can depend on credits. When a category is paused, a message says it is coming back soon and can be used now by adding credits, while slideshows and websites remain available with no limits.
The leaderboard API is a separate track: its data is free to use for personal and commercial projects.
The closest comparison is a text-first arena. An independent news report described LM Arena as taking a similar approach to text-based responses. That service, now called Arena and hosted at arena.ai, also lists leaderboards for WebDev models, text models, image generation and video generation, so the two overlap on web and image tasks while differing in origin and emphasis.
Artificial Analysis takes a different route: it publishes independent benchmarks of AI models and API providers across quality, price, output speed and latency. It also runs Image Arena and Video Arena leaderboards, which makes it the better fit when cost and speed matter as much as taste.
| Option | Main signal | Best fit |
|---|---|---|
| Design Arena | Blind crowd votes on visual and interactive output | Websites, UI, slides, logos, games |
| Arena.ai | Crowd votes, text-first with WebDev and media boards | Chat and general model choice |
| Artificial Analysis | Measured quality, price, speed, latency | Cost and performance trade-offs |
Design Arena's own pages do not describe the ranking rules identically:
Rankings therefore reflect crowd preference under these rules, not a fixed test suite, and a new entry can shift noticeably.
User prompts are moderated through an API call to gemini-2.5-flash-lite-preview-09-2025, a model the notes say was chosen for cost. The published moderation instructions also ask it to check prompts for anything political, political people, or political or religious symbols, so topical or campaign-style design briefs may be flagged.
Basic prompting and voting carry no fee under the terms, within free usage limits that vary by category and prompt complexity. Prepaid credits of $5 to $100 cover usage beyond those limits, and Premium mode charges the actual cost per generation.
Votes from blind, head-to-head matchups feed a Bradley-Terry model, which produces Elo-style ratings. The leaderboard refreshes every two hours, and models with fewer than 50 votes are marked as new.
Yes. The Design Arena API is free for personal and commercial projects after an application is approved, but public use must credit Design Arena and link to designarena.ai.
Prompts, outputs and uploaded media may be shared with third-party AI technology providers, including for training. Design Arena takes steps to remove usernames and email addresses first, but personal details written inside the content itself may still be shared.
No. Arena (formerly LMArena and Chatbot Arena) is a separate platform focused on evaluating large language models, while Design Arena, from Arcada Labs Incorporated, ranks models on visual and interactive design output.
