Bolt.new

Bolt.new is StackBlitz's AI-powered full-stack web app builder — you describe an app in plain English and Bolt generates the code, runs it live in the browser, and deploys it to production with one click. We rate it 73/100 — a genuinely magical prototyping tool that collapses a weekend of scaffolding into a 20-minute prompt, with real trade-offs around token cost, debugging, and production readiness.

What is Bolt.new?

Bolt.new launched on October 4, 2024 from Eric Simons's StackBlitz, a 7-year-old Oregon-based startup that had quietly built the WebContainers technology powering StackBlitz.com. The bet: run a full Node.js stack — filesystem, terminal, package manager — inside a browser tab, then hand the keys to an LLM so an AI agent can prompt, edit, install packages, run code, and ship the result to production without ever leaving the tab.

The bet worked. Bolt hit $4M ARR in 30 days, $20M ARR in 60 days, and $40M ARR in five months, making it one of the fastest-growing software products in history behind ChatGPT. In January 2025 StackBlitz closed a $105.5M Series B led by Emergence Capital and GV at a $700M valuation, bringing total funding to $135M. The open-source reference implementation on GitHub has 16.3k stars under the MIT license, and the main product has powered over one million websites through a deployment partnership with Netlify.

Key Features of Bolt.new

• Full-stack in the browser via WebContainers: Bolt installs npm packages, runs Node servers, and exposes a real shell — all client-side in WebAssembly. No Docker, no SSH, no local setup. Your app boots in under five seconds.
• Single-click deploy to Netlify: Type "deploy" and Bolt ships your app to a live URL. Pro accounts bind custom domains, and paid tiers unlock SEO boosting and private site sharing.
• Click-to-edit visual inspector: Click any element in the preview and Bolt lets you adjust copy, colors, spacing, or layout — it patches the underlying code on the spot, the way Webflow users expect to work.
• Design-system aware: First-class support for Material UI, Chakra, Shadcn, Tailwind, and partner kits from Porsche and Washington Post, so generated UI is not just "AI-generic" templates.
• Figma and Expo integrations: Bolt x Figma (launched March 13, 2025) imports designs directly into a running app, and Bolt + Expo (February 13, 2025) extends the same prompt-to-app loop to React Native for iOS and Android.
• Open-source core: The agent stack is public under MIT on GitHub as stackblitz/bolt.new, and community forks like bolt.new-any-llm let you swap in Ollama, Gemini, Groq, or DeepSeek instead of the hosted model.
• Viral referral program: Invite a friend and you both get 200k tokens instantly; if they upgrade to Pro within 30 days, both sides get 5M bonus tokens — powered by GrowSurf and cited as one of the fastest-growing referral loops of 2025.

What Users Say About Bolt.new

Sentiment is genuinely split. On Product Hunt, Bolt's original launch racked up 1,239 upvotes with founders calling it "the fastest way from idea to landing page I have ever seen." On the flip side, Bolt holds a brutal 1.4/5 on Trustpilot, where the complaints cluster around opaque token consumption, billing issues, and slow support responses.

The most-cited Reddit critique from r/SideProject: "Bolt got me to a demo in 20 minutes. It took me two more weeks to add auth and a real database. I should have started with Replit or Emergent." Multiple Redditors report burning 5–8 million tokens on a single Supabase auth bug before giving up and writing the fix by hand. The consistent praise: speed of first draft, quality of generated UI with Tailwind or Shadcn, and the click-to-edit inspector. The consistent pain: token costs on iterative debugging, auth/database edge cases, and the moment your app outgrows what the agent can hold in context.

Bolt.new Pricing

Bolt uses a token-metered freemium model. All plans include hosting and unlimited databases; tokens are how you pay for the AI agent's work.

Plan	Price	Key Limits
Free	$0/month	300k tokens/day, 1M/month, 10 MB uploads, 333k web requests, Bolt branding on sites
Pro	$25/month	10M tokens/month with rollover, 100 MB uploads, custom domains, no branding, AI image editing, 1M web requests
Teams	$30/user/month	Everything in Pro plus centralized billing, SSO-lite admin controls, private NPM registry, design-system knowledge
Enterprise	Custom	SSO, audit logs, dedicated account manager, 24/7 priority support, data governance

Token overage is the thing to watch. Redditors regularly hit the 10M cap in under two weeks during active development; buying extra tokens quickly pushes real monthly spend past $100 for serious users.

Who Should Use Bolt.new?

Best for: Product managers, designers, founders, and developers who need a working MVP in hours, not weeks. Side-project builders validating ideas on evenings. Agencies delivering clickable prototypes to clients. Anyone who has a clear idea and wants to skip the yak-shaving of bootstrapping Next.js, auth, a database, and a deploy pipeline.

Not ideal for: Teams shipping to production with strict uptime, security, or compliance requirements — Bolt is still rough on long-horizon debugging and will happily re-architect working code on a reprompt. Also not ideal if you are deeply cost-sensitive: the pay-per-token model can bite when the agent goes in circles on a tricky bug.

Pros and Cons

Pros:

• Fastest path from text prompt to deployed full-stack app currently on the market.
• WebContainers architecture means no local environment, no Docker, no deploy pipeline to configure.
• Click-to-edit visual inspector and design-system awareness produce surprisingly non-generic UI.
• Open-source core (MIT, 16.3k stars) means you can self-host a variant with your own LLM provider.
• Tight Figma and Expo integrations extend the same loop into design and mobile.

Cons:

• Trustpilot 1.4/5 reflects real complaints: opaque token burn, billing friction, slow support.
• Auth and database edge cases (especially Supabase) can consume millions of tokens with no resolution.
• Generated code quality degrades as apps grow past a few thousand lines — refactors get flaky.
• Pro plan's 10M tokens feels generous for a day and tight for a month of serious building.

Alternatives to Bolt.new

The AI app-builder market split wide open in 2025. Lovable (Sweden) matches Bolt on speed and edges it on UI polish for consumer apps. v0 by Vercel leads on component-level fidelity inside a Next.js shell. Replit with Agent 3 offers a deeper, more traditional IDE experience and better long-project continuity. Emergent.sh and Windsurf Wave target developers who want an AI that understands existing codebases, not just greenfield prompts.

Verdict: Is Bolt.new Worth It?

Yes, with eyes open. For $25/month, Bolt.new replaces the first weekend of a side project — the part where you pick a framework, set up auth, wire a database, and configure a deploy pipeline — with a 20-minute prompt. That is genuine, discontinuous value. The caveat is that Bolt is much better at starting than finishing: the closer you get to production, the more the generated code fights back. Treat it as the world's best scaffolder and velocity-multiplier for early ideas, not as a replacement for a senior engineer on a maturing codebase, and the 73/100 feels earned.

Frequently Asked Questions

Is Bolt.new free?

Yes, Bolt.new has a permanent free plan with 300k tokens per day and 1M tokens per month, plus hosting and unlimited databases. Paid plans start at $25/month for Pro.

What platforms does Bolt.new support?

Bolt.new runs entirely in the browser — any modern Chrome, Edge, Safari, or Firefox works. Via the Bolt + Expo integration, it also generates React Native apps for iOS and Android.

How does Bolt.new compare to Lovable and v0?

Bolt.new is broader in scope (full-stack, Node backend, deploy included) and the fastest to a working app, but its output can be rougher. Lovable produces cleaner consumer UIs; v0 produces the best individual React components inside Next.js.

Is Bolt.new open source?

The agent core is open source under MIT at github.com/stackblitz/bolt.new (16.3k+ stars). The hosted product, WebContainers runtime, and Bolt x Figma / Bolt + Expo integrations are commercial.

Who built Bolt.new?

Bolt.new is built by StackBlitz, founded by CEO Eric Simons. StackBlitz raised $105.5M Series B in January 2025 at a $700M valuation, led by Emergence Capital and GV.
