frascati vs Bolt.new vs v0: which one fits your project

frascati, Bolt.new and v0 all turn a written description into code. That is where the similarity ends. Each one is made for a different job, and picking the one that fits saves you time.

frascati is our product. We describe all three by what they are made for and say plainly where frascati does not fit. Bolt.new and v0 change their plans from time to time, so we leave their prices out.

The core difference

The quickest way to tell them apart is by what they produce. frascati builds complete websites for businesses. Bolt.new by StackBlitz builds and runs projects in the browser, from prototypes to web apps. v0 by Vercel generates React UI and apps.

frascati: websites from a conversation

You describe your business, or paste the address of your current website so frascati can use the text of that page. About two minutes later you have a first version: several pages with real copy, fitting photos, a contact form, and a title and description for every page. Then you change it by writing in the chat. After each answer, frascati suggests three next steps you can click.

It does not make things up. Prices, opening hours, reviews or team members it does not know are left as visible [placeholders]. Every change is saved as a version, so you can compare and go back. Plan mode lets you ask questions without changing the site. If you want to see the code, the Code view shows every file and you can edit it directly.

Where frascati falls short: it builds websites and phone apps, not full web apps. A website can sign visitors in with a code by email, keep a members area and show each person their own entries and bookings, but there are no roles, no server code of your own and no database you design. It does have online booking and a small shop with a cart, paid through your own Stripe account, but no stock levels or product variants.

Bolt.new: build and run in the browser

Bolt.new is made by StackBlitz and runs your project inside the browser with WebContainers. You describe what you want, Bolt.new writes the code, and you see the project running. You can work on the code directly, which suits people who want to understand and shape what is being built.

It fits best when you are building an app or a prototype and want the whole project in front of you. If all you need is a business website, a website builder is likely the shorter path.

v0: React UI and apps

v0 is made by Vercel and generates React UI and apps from a description. It fits people who work in React or who hand the code to a developer, for example to add a new screen to a product or to start an app.

It is the natural pick when the result has to live in a React codebase. If you do not work with code at all, a website builder is likely simpler.

How they charge

Bolt.new and v0 have their own plans and change them from time to time. Check their websites for current prices and limits.

frascati is a paid product with three plans. Every plan starts with a free 3-day trial with 20 credits. A card is required, and if you cancel before the trial ends, nothing is charged.

Pro and Business can be booked with more credits a month for a higher price, and paying yearly costs 10 months instead of 12. Credits pay for the AI work: a new website uses about 3 credits, most changes less than 1 and a question in Plan mode 0.1 to 0.5. Fixing an error in the preview is free, up to 10 times a day. Once your plan has started, you can buy credit packs, from 22 credits for $10.

Common scenarios

Scenario 1: a website for your business

Best fit: frascati. Pages, copy, photos, a contact form and publishing in one click are exactly what it is made for. Bolt.new and v0 can build a website too, but they are made for broader jobs and expect you to be closer to the code.

Scenario 2: a web app with logins and a database

Best fit: Bolt.new, or v0 if you work in React. frascati is the wrong tool here: its sign-in by email code covers a members area on a business website, but there are no roles, no server code of your own and no database you design.

Scenario 3: a new screen for an existing React project

Best fit: v0. It generates React UI that you or a developer can take into the project.

Scenario 4: a portfolio online this week

Best fit: frascati. Start from the portfolio template or a short description, fill in the placeholders and publish in one click. Our portfolio guide walks you through it.

Frequently asked questions

Can I use frascati and v0 together?

Yes, for different jobs. For example, v0 for your product's interface and frascati for the website that presents your company.

Which AI models do they use?

frascati uses Anthropic's Claude models: Claude Opus 5.5 builds new websites and Claude Sonnet 5.5 makes the changes. Bolt.new and v0 choose their own models, which can change, so check their websites.

Which one is best for a simple business website?

frascati, because that is the job it is built for: copy, photos, a contact form, a title and description for every page and publishing in one click. Bolt.new and v0 can also produce a website, but they expect you to be closer to the code.

Can I use my own domain?

With frascati, yes, on the Pro and Business plans: frascati shows the DNS records to set at your domain provider. Starter sites are published at a frascati address. Bolt.new and v0 have their own ways to put a project online; see their websites for the details.

Can people who do not code use these tools?

frascati is made for them: you describe, it builds, you publish. Bolt.new and v0 can be used without writing code too, but they show you the code and make the most sense if you can read it.

The verdict

These three tools overlap less than it seems. frascati is for complete business websites you publish yourself. Bolt.new is for apps and prototypes you build and run in the browser. v0 is for React interfaces and apps that you or a developer will take further.

Start from the scope of your project. A website or a phone app for your customers, also with a simple members area: frascati. A web app with roles, its own database and server code: Bolt.new. React code for your own project: v0.
