Bolt.new

Bolt.new is StackBlitz's AI-powered app builder that generates full-stack web applications, prototypes, and websites directly in the browser from natural-language chat. Launched in late 2024, Bolt has positioned itself as the leading professional vibe coding platform, enabling product managers, entrepreneurs, marketers, and non-developers to ship working applications without traditional coding workflows. The platform runs on StackBlitz's WebContainer technology, executing Node.js applications natively in the browser without server-side compute. Bolt integrates frontier coding agents from multiple AI labs into a single visual interface, automatically testing, refactoring, and iterating on errors rather than requiring developers to fix them manually. The platform's primary differentiator is design system integration: Bolt supports Porsche Design System, Material UI, Chakra UI, Shadcn UI, and the Washington Post Design System out of the box, allowing product teams to generate apps that match their brand and component standards without manual styling. Import from Figma and GitHub brings existing designs and codebases into the Bolt workflow. Built-in infrastructure includes hosting with analytics, unlimited databases, user management and authentication, SEO optimization, and custom domain support, eliminating the need for separate backend platforms during prototyping and early production. The context management engine has been significantly expanded to handle projects substantially larger than the platform's earlier versions. Pricing follows a tiered structure with annual billing available for up to 28% savings. Free at $0/month includes 300K daily tokens, 1M monthly tokens, public and private projects, Bolt-branded hosting, 10MB file uploads, and unlimited databases: sufficient to validate the platform and build small projects without payment. Pro at $25/month removes Bolt branding, lifts daily token limits, increases monthly tokens to 10M with rollover, expands file uploads to 100MB, adds custom domain support, SEO boosting, expanded database capacity, choice of database provider, and AI image editing. Teams at $30/user/month adds centralized billing, team-level access management, granular admin controls, user provisioning, private NPM registry support, and design system knowledge with per-package prompts. Enterprise pricing is custom with SSO, audit logs, compliance support, dedicated account management, and custom SLAs. Third-party review signal for Bolt.new is limited and mixed. G2 shows 3.1 out of 5 from 6 reviews as of May 2026, with recurring themes around token limits on the free tier and the gap between prototype output and production-ready code. The official GitHub repo (stackblitz/bolt.new) has 16,400 stars, though it functions primarily as a public template rather than an actively developed open-source codebase. The community-built fork bolt.diy (stackblitz-labs/bolt.diy) has 19,400 stars and is more actively maintained for self-hosted use cases with any LLM. Bolt.new is not the right fit for developers who need production-grade, maintainable codebases from day one. Generated apps work well for prototypes and demos, but moving to production typically requires GitHub export, manual code review, and migration to standard hosting infrastructure. Developers who prefer terminal-based or IDE-embedded workflows should evaluate Cursor at $20/month or Claude Code Pro at $20/month, both of which provide more control over the generated code and git integration without the browser-first constraint. Teams building compute-heavy applications requiring native dependencies, GPU access, or long-running background jobs will hit WebContainer execution limits and need Replit or self-hosted environments. Current state Q2 2026: Bolt has added "Plan" mode alongside "Build now" for structuring projects before generation. User management and authentication are now built into the platform as included features. Context management has been expanded to handle significantly larger and more complex projects than at launch. Enterprise tier is available with SSO, audit logs, and compliance support for organizations with procurement requirements.
