Bolt.new is an in-browser AI builder that turns a text prompt into a running full-stack web app, with hosting, databases, and auth included.
Bolt.new is an in-browser AI development tool that turns a plain-English description into a running full-stack web application without any local setup. You type what you want to build, and Bolt generates the code, runs it instantly in a live preview, and deploys it to production-grade hosting with databases and authentication built in. For AI builders, Bolt is a fast path to shipping working prototypes, automating internal tool creation, and iterating on ideas before committing to a full engineering build.
Bolt runs a full development environment inside your browser tab. Here is the sequence from prompt to deployed app.
Prompt: You describe the app in plain English, such as “Build a task manager with user login and a Kanban board.” Bolt parses the description and decides the tech stack, file structure, and implementation approach automatically.
Code generation: Bolt writes code across multiple files simultaneously, handling the frontend (the interface a user sees), the backend (server-side logic), and the database schema. It routes each task to the best available AI model automatically, so you do not need to choose between Claude, GPT-4, or others manually.
Live preview: As Bolt writes, the app runs in a sandboxed browser environment in real time. You see and interact with the result immediately, click through flows, and type follow-up prompts to fix or extend anything.
Iteration: Every follow-up message is a code edit. “Make the sidebar blue”, “Add a search bar”, “Fix the login redirect.” Bolt reads the full project context on each prompt and applies targeted changes without breaking the rest of the app.
Deployment: When ready, you publish to Bolt Cloud in one click. This provides hosted infrastructure, a managed database, authentication, SEO configuration, and a custom domain, with no separate accounts on Vercel, Supabase, or Auth0 needed.
SaaS MVP: Describe a product idea, and Bolt scaffolds the full application: authentication, a database-backed user dashboard, and a Stripe payment integration. Ship a working demo to early users in hours instead of weeks.
Internal business tools: Build a custom admin panel, CRM dashboard, or data reporting tool tailored to your team’s workflow. No need to pay for off-the-shelf software that does 80% of what you need. Describe the specific fields, filters, and views you want.
AI-powered web app: Connect to OpenAI, Anthropic, or any LLM API by describing the integration in your prompt. Bolt scaffolds the API calls, the chat interface, and the frontend. A working AI chatbot, document summariser, or content generator is a single session away.
Marketing landing pages and campaign sites: Generate high-converting landing pages with custom copy, SEO metadata, and Bolt Cloud hosting. Spin up a new page for each campaign without involving a developer. Bolt handles the code; you handle the messaging.
Prototype for design handoff: Build a clickable, functional prototype from a Figma import or a text description. Give stakeholders something they can actually use before a single sprint is planned. Collect real feedback on real interactions.
E-commerce storefront: Describe a product catalogue with cart and checkout, and Bolt integrates Stripe for payments. A functional store with dynamic inventory is achievable without a Shopify subscription or a custom build from scratch.
No. Bolt.new is designed for anyone who can describe what they want in plain English. Non-technical users build landing pages, dashboards, and MVPs without writing a line of code. Developers also use it to skip boilerplate and iterate faster. The tool works across skill levels, from first-time builders to senior engineers who want to prototype quickly.
Bolt.new supports full-stack web applications, including frontends, backends, and databases. Common builds include SaaS MVPs, internal tools like admin dashboards, marketing landing pages, e-commerce stores with Stripe, portfolio sites, and AI-powered apps that call LLM APIs. Bolt handles the entire stack in one environment, so you can go from idea to deployed app in a single session.
Both Bolt.new and Lovable build full-stack apps from prompts, but they differ in pricing model and target user. Bolt uses a token-based system where costs scale with project size, making it better for solo developers building complex apps. Lovable uses a credit-based model shared across unlimited team members at $25 per month, making it more cost-effective for teams. Bolt tends to offer more control over the codebase.
