Bolt.new is an AI-powered, browser-based app builder that converts natural-language prompts into full‑stack, deployment‑ready web and mobile apps by generating frontend (React + Tailwind), backend (Node/Express), database schemas (Postgres + Prisma) and auth/APIs in seconds. Its AI handles project planning, context management and code generation with advanced reasoning models while a visual editor lets non‑developers tweak layouts, inspect/debug code, generate content, and export clean source code with no vendor lock‑in. Users choose Bolt.new to rapidly prototype and validate MVPs, build marketing or lead‑gen tools, and skip boilerplate engineering—saving time and cost while making app creation accessible to non‑developers.
