Bolt.

Setting up a development environment used to be the first hurdle of every project — installs, configuration, servers, deployment pipelines. Bolt removes all of it. Built by StackBlitz, Bolt (at bolt.new) lets you create, run and deploy full-stack websites and apps by chatting with AI, entirely inside your browser. In this Bolt review, we cover how it works, what the token-based pricing really gives you, and who it suits best.

What Is Bolt?

Bolt is an AI-powered app and website builder that runs in the browser. You describe what you want to build, and Bolt generates the project, runs it in a live in-browser development environment (powered by StackBlitz’s WebContainers technology), and lets you keep editing through conversation or by working with the code directly. When the app is ready, Bolt Cloud handles the production side — hosting, databases and integrations.

What sets Bolt apart from simple prompt-to-webpage toys is that it behaves like an agent, not an autocomplete. Bolt automatically routes each task to the AI model it judges best for the job, balancing quality and cost, and it tests, refactors and iterates on its own output to cut down errors while you build.

Key Features

• Chat-based building: Create apps and websites by describing them in plain language, then refine with follow-up prompts or direct code edits.
• In-browser development environment: Your project runs live in the browser — no local setup, no installs, nothing to configure before the first build.
• Automatic model routing: Bolt picks the right AI model for each task instead of making you juggle platforms or guess which agent to use.
• Self-checking agent: Bolt automatically tests, refactors and iterates on the code it writes, reducing the error-fix loop common in other builders.
• Bolt Cloud backend: Enterprise-grade hosting, databases and integrations built in — including unlimited databases even on the free plan — so you do not stitch together separate platforms.
• Custom domains and SEO: Paid plans let you publish on your own domain with no Bolt branding, and Pro adds SEO boosting for published sites.
• Team controls: The Teams plan adds centralized billing, access management, granular admin controls and priority support.
• Enterprise security: The Enterprise tier adds SOC 2 Type II, SSO and data governance on dedicated infrastructure.

How to Use Bolt

1. Open bolt.new and describe your idea. Type what you want — a landing page, a dashboard, a small web app — in the chat box. No account setup or local install is needed to start.
2. Watch it build and run. Bolt generates the project and runs it in the browser preview, so you can click through the working app immediately.
3. Iterate by chatting or editing. Ask for features and fixes in plain language, or step into the code yourself and edit alongside the AI.
4. Add a backend if you need one. Use Bolt Cloud’s built-in databases and hosting rather than wiring up external services.
5. Publish. Deploy your site or app from the same interface; add your own domain on a paid plan to remove Bolt branding.

Bolt Pricing

Bolt meters usage in AI tokens rather than credits or messages. The important detail is that token use is mostly about syncing your project’s file system to the AI — the bigger the project grows, the more tokens each message tends to use. Pro includes token rollover, so unused tokens are not simply lost at the end of the month.

Plan	Price	What you get
Free	$0	Free forever, no card required: 1M tokens a month (300K daily limit), public and private projects, unlimited databases and hosting, with Bolt branding on websites
Pro	$18/month	Billed annually ($216/year): your own domain with no Bolt branding, 10M tokens a month with rollover, expanded database capacity, access to the newest AI models and SEO boosting
Teams	$27/month	Per member, billed annually: everything in Pro plus centralized billing, team access management, granular admin controls and priority support
Enterprise	Custom	Custom annual contract billed by consumption: unlimited tokens, SOC 2 Type II, SSO, data governance, dedicated infrastructure and account manager, 24/7 support

The free plan is unusually capable for testing: real monthly tokens, private projects and hosting without handing over a card. The jump to Pro is mainly about capacity and presentation — ten times the tokens, rollover, a custom domain and no branding.

Pros

• Zero setup: building and running happen in the browser, so anyone can start in seconds.
• Free plan is free forever with no credit card, and even includes private projects and databases.
• Automatic model routing means you always get a suitable AI model without managing subscriptions elsewhere.
• Bolt Cloud folds hosting, databases and integrations into one place — nothing extra to wire up.
• Pro’s token rollover makes the paid plan more forgiving for bursty, project-based work.

Cons

• Token consumption grows with project size, so large projects can burn through allowances faster than expected.
• The free plan carries Bolt branding and a 300K daily token cap that can interrupt long sessions.
• Headline Pro and Teams prices are annual-billing prices; month-to-month costs more.
• Because everything runs through Bolt’s environment, developers who want a fully local, self-controlled workflow may find it constraining.

Who Should Use Bolt?

Bolt is ideal for founders, designers and indie builders who want a working prototype or small product without touching a local dev setup, and for developers who want to skip boilerplate and test ideas at full speed. If your project needs a long-lived, heavily customised backend maintained by an engineering team, Bolt works best as the fast first draft rather than the final foundation.

Bolt Alternatives

The closest alternative in this category is Lovable, which leans further toward non-technical builders with a fixed React and Supabase stack and a credit-based pricing model. You can compare both — and browse every new AI app builder we review — in the BetaTools directory.

Frequently Asked Questions

Is Bolt really free?

Yes. Bolt’s free plan is free forever and needs no credit card. It includes 1M tokens per month with a 300K daily limit, public and private projects, unlimited databases and website hosting, with Bolt branding shown on websites.

How much does Bolt Pro cost?

Pro costs $18 per month billed annually ($216 per year). It includes 10M tokens a month with rollover, a custom domain with no Bolt branding, expanded database capacity and access to the newest AI models.

What are tokens in Bolt?

Tokens are how Bolt measures AI usage. Most token use comes from syncing your project’s files with the AI, so larger projects use more tokens per message.

Who makes Bolt?

Bolt is built by StackBlitz, the company behind the WebContainers technology that lets a full development environment run inside a browser tab.

Can Bolt handle big projects?

Bolt says its improved built-in context management can handle projects much larger than before, backed on paid plans by Bolt Cloud’s hosting and database infrastructure.

Final Verdict

Bolt is the fastest on-ramp in the AI app builder category: open a tab, describe the thing, and watch it run. The free plan is generous enough to judge it properly, and Bolt Cloud removes the usual backend patchwork. Mind the token meter as projects grow, and Bolt rewards you with serious speed.
