Bolt.new by StackBlitz is a browser-based AI app builder that generates full-stack Next.js and React applications from natural language prompts, running entirely inside WebContainers — a local Node.js runtime that executes in the browser without remote servers. As of mid-2026, the platform supports full-stack scaffolding, package installation via npm, database provisioning, integrated hosting via Bolt Cloud, and a self-healing runtime that monitors build logs and auto-fixes dependency conflicts. The v2 release introduced Figma import, design system templates, and natural language styling for non-developers, plus the ability to handle projects roughly 1,000× larger than the 2025 release through improved context management. Pricing follows a token-based model: Free ($0/month, 1M tokens/month with a 300K daily cap, unlimited projects, Bolt branding), Pro ($25/month or ~$18/month annually, 10M tokens, no daily limit, priority queue, email support), Teams ($30/month per member, 10M shared tokens, collaborative workspace), and Enterprise (custom pricing, negotiated tokens, dedicated account manager). Annual billing saves roughly 28%. Token consumption scales with project complexity and codebase size rather than a flat per-generation rate, making cost prediction genuinely difficult for larger applications. User feedback is sharply polarized. Enthusiastic reviewers praise its speed — benchmarks from January 2026 show a 40% build performance improvement over 2024 — and its ability to scaffold working SaaS prototypes in hours rather than weeks. However, Trustpilot and Product Hunt reviews are flooded with complaints about opaque token burn (users report 200K–1M tokens consumed for "simple" changes), unreliable auto-fix loops that break unrelated components, and customer support that is widely described as unresponsive or AI-only. The free tier is functional for small prototypes but impractical for anything beyond hobby projects due to the daily cap.
