Bolt.new is the fastest path from a sentence to a running full-stack app, and the in-browser WebContainer runtime is a genuine technical edge over rivals that only generate code. The trade is token economics: iteration burns budget in ways a flat IDE subscription does not, and the output still wants a developer's eye before it ships. Strong for prototyping and for non-developers reaching a first working product.
- Runs a full Node.js stack in the browser via WebContainers, zero setup
- Prompt to a running, editable, deployable app in one flow
- Free daily token allowance to try real builds before paying
- Expo integration generates React Native apps for iOS and Android
- Bolt Cloud adds hosting, database, auth, and Stripe in one place
- Token-based pricing makes heavy iteration cost hard to predict
- Browser WebContainer runtime limits some native and heavy workloads
- Mobile output still needs manual EAS setup for store deployment
- Generated code can need cleanup before a team adopts it long term
- Weaker fit than an IDE agent for large existing codebases
Bolt.new is StackBlitz’s AI app builder that turns a prompt into a running, editable, deployable application without any local setup. It pairs zero-shot code generation with WebContainers, the StackBlitz technology that runs a full Node.js environment inside the browser tab. It is aimed at founders, product people, and developers who want to reach a working prototype in minutes rather than scaffolding one by hand.
Where it fits
The core loop is prompt to full-stack app, live in the browser. Bolt scaffolds the project, installs dependencies, runs the dev server in a WebContainer, and lets you edit and redeploy in place. Because the runtime is real Node, you see the actual app rather than a static preview, and you can publish to a custom domain when it is ready.
It fits two audiences. Non-developers use it to reach a first shippable product without touching a terminal. Developers use it to spike an idea fast, then move the code into a real editor if it has legs. As an alternative to Lovable and v0, Bolt’s differentiator is that the app genuinely runs in the browser, not just the generated source.
Pricing in practice
Bolt is freemium and the meter is tokens, not seats. The free tier gives a daily token allowance (around 300K per day, capped monthly) that is enough to evaluate real builds. Pro starts near $20 per month with a multi-million-token monthly pool, Teams is priced per member, and Enterprise is custom.
The cost reality is iteration. Every prompt, fix, and regeneration spends tokens, so a stubborn bug or a heavily reworked feature can burn through an allowance faster than the flat monthly fee suggests. Token rollover (unused tokens carry one extra month) softens this, but teams should budget for the build pattern, not just the sticker price.
How it compares
Lovable, the closest rival on prompt-to-app for the web. Lovable leans design-forward and polished UI; Bolt’s edge is the real in-browser runtime and Expo mobile path.
v0, Vercel’s generator is strongest at React and shadcn UI components that drop into a Next.js project. Bolt builds and runs the whole app, where v0 focuses on the frontend layer.
Cursor, an AI IDE for working inside an existing codebase. Cursor wins on large repos and developer control; Bolt wins on going from nothing to a running app with no setup.
What changed recently
Bolt.new launched on 2024-10-03 and grew at a rate that drew industry attention, reaching roughly $20M ARR within two months and an estimated $40M ARR by March 2025 (Sacra), on the back of StackBlitz’s $135M raised and a reported $700M valuation by August 2025. In February 2025 Bolt added native mobile support through an Expo partnership, generating React Native apps for iOS and Android from a prompt (store deployment still needs manual EAS setup). Bolt Cloud arrived in August 2025, folding hosting, databases, authentication, serverless functions, and Stripe into the platform, and the current builder defaults to a Claude-based agent with intelligent model routing.
