Which one is for you

Pick Polymet if

Fits if you want working React screens from a prompt, to hand to developers
Works for teams that already keep a design system or Figma files

Look elsewhere if

Skip it if you want a finished app with logins and payments built for you, as it is aimed at design and front end
Tight if you stay free: 500 credits a month, 250 a day, and a Polymet badge on anything you publish
Pricey if you need code download, GitHub export or a custom domain, all Pro at $25 a month for 1,000 credits
Watch out: Team is $50 for the same 1,000 credits, and there is no phone or desktop app

Pick v0 if

Fits if your team already deploys on Vercel
Works for designers or product managers with a mockup to turn into a working interface

Look elsewhere if

Pricey if you're a team, since Plus is $30 for every user and Business $100
Not for you if you want a free plan to stay on, as new accounts get a one-time $5 of credits and a 7-message daily limit
Skip it if you expected it with your Vercel plan, because v0 is billed separately
Watch out: generation pauses when your credits run out, until you buy more
Watch out: Plus is shown beside a crossed-out $90 with no end date, and there's no Android or desktop app

How we grade them

	2.4GPAPolymetFair	2.4GPAv0Fair
Value for money	C$25 a month for 1,000 credits sits at the top of the $15 to $25 range this category charges, and Team costs $50 for the same credits. The paid plan is what unlocks code download and custom domains.	DPlus is $30 per user a month, past the $29 where the dearest tenth of builders here begins, and every teammate pays it. You get $30 of credits back monthly plus $2 a day on login, but when they run out generation stops until you buy more. Business is $100 per user, and none of it comes with a Vercel plan.
Free plan and trial	CFree gives 500 credits every 30 days, capped at 250 a day, with unlimited projects. Published apps carry a Built with Polymet badge, and unused free credits do not carry over.	CNew accounts get $5 of credits, once, with a 7-message daily limit. They never renew, and free users can't even buy more without upgrading, so it's a short trial rather than a plan. Design Mode and GitHub sync are included while it lasts.
Features	BCanvas, visual and code editors, Figma and GitHub in and out, a design system, a backend and publishing. Nothing in the listing is missing from the job of building front-end screens, though credits run out faster on big builds.	BIt covers the whole job: a prompt, a screenshot or a Figma file becomes a working full-stack app, and it diagnoses and fixes its own errors. Design Mode edits by eye, every branch gets a preview URL, GitHub sync shows the diff, PR and CI checks, and Supabase or Neon plug in. Bolt matches it, so no A.
Ease of use	CA browser app where the work is describing and shaping the thing you are building. No store rating is on record, so there is nothing to lift it higher.	B4.8 from about 850 App Store ratings, under the thousand we want behind an A. Prompt it, then adjust the result by eye in Design Mode, which is on the free plan too, so you're not re-prompting for every small change.
Platforms and integrations	BWeb only, but it links to Figma, GitHub, Storybook, npm and Claude Code through its MCP server.	BThe web plus an iPhone app, with no Android or desktop app listed. It connects to Vercel, GitHub, Figma, Supabase, Neon, Upstash, Snowflake and Shopify, and a REST Platform API and SDK let your own code drive it.
Best for	turning a prompt into front-end screens and prototypes	teams that already deploy on Vercel

Worth knowing

Polymet

Credits are spent by AI model usage per message, so large builds use more than short edits; nothing is billed past zero and generations stop when credits run out.
Custom domains, code download, GitHub export, removal of the Polymet badge and premium models are Pro-plan features.
A Keep Alive option at $8 a month keeps a finished project online after a paid plan is cancelled, with 300 credits a month on top of the free 500.
Unused free credits do not carry over; paid plan credits roll over for 30 days after each renewal. The product is a browser app only.

New Free accounts get $5 of credits once; they do not renew, and Free users must upgrade to buy more.
Paid plans are priced per user, and generation pauses when credits run out until more are bought.
A v0 plan is separate from a Vercel subscription and is not included in Vercel Hobby, Pro or Enterprise.
The site lists an iOS app but no Android or desktop app.

Key features

Polymet

Prompt-built canvas: The Polymet agent turns a prompt into pages and components on a canvas, as a React and Tailwind app you can click through.
Visual and code editors: Tweak layout, spacing and colors visually, select an element and edit it with AI, or open the code editor for direct control.
Design systems and Figma: Bring your own design system, import Figma files into a project and export designs back to Figma.
GitHub and coding agents: Import from GitHub or a ZIP with two-way sync, export code to a repository, and build in Polymet from Claude Code and other coding agents through its MCP server.
Backend and publishing: Projects can add a backend with managed data and secrets, publish to a polymet.app link, and use custom domains on paid plans.
Team collaboration: Invite members with Admin and Member roles, work live in the same project, and keep versions and branches.

Prompt-to-app agent: Describe an idea, or attach a screenshot or Figma file, and v0 generates the interface and code, then diagnoses and fixes errors as it iterates.
Design Mode: Edit a generated interface visually instead of re-prompting. Design Mode is listed among the features of the Free plan.
Deployments on Vercel: Working branches get preview deployments with their own URLs, and publishing updates the project's production deployment, with custom domains available.
GitHub sync: Projects can be backed by a GitHub repository, with the branch diff, pull request and CI checks visible next to the Publish button.
Database integrations: One-click integrations with Upstash, Neon, Supabase and Vercel Blob add data persistence, and a Snowflake connection supports data apps.
Model choice and Platform API: Four v0 models are priced per million tokens, from v0 Mini to v0 Max Fast. A REST Platform API and SDK expose projects and chats to your own code.

How this page was made

The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
The grades are our own, from each tool’s review or report card. The GPA is their average.
Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
