Key features
  • Full-Stack App Generation (historical)
  • Cloud-Based IDE (historical)
  • Mobile & Backend Support (historical)
  • In-Browser Node.js Runtime (WebContainers)
  • Bolt Agent (auto model routing: Standard / Max)
  • Full-Stack App, Website & Mobile Generation
  • Bolt Cloud (databases, auth, hosting, SEO)
  • Figma & GitHub Import
  • One-Click Netlify Deployment
  • Mobile Preview via Expo (iOS/Android, QR code)
  • Design System-Aware Generation
Pros
  • Was fully free with a generous workspace allowance before sunsetting
  • Deep integration with Firebase/Google Cloud services while active
  • Genuine in-browser Node.js runtime (WebContainers) — zero local setup to start building
  • Multi-framework flexibility: React, Next.js, Vue, Svelte, Astro, Angular and more
  • Full, exportable code control rather than a black-box generator
  • Bolt Cloud bundles databases, auth, hosting and SEO instead of requiring separate services
  • Strong for fast, early-stage prototyping and sharing runnable demos
  • Mobile app generation via Expo extends it past web-only building
Cons
  • New workspace creation and signups disabled as of June 22, 2026
  • Scheduled for full shutdown on March 22, 2027
  • Google is redirecting users to Google AI Studio or Google Antigravity instead
  • Token consumption is the most common complaint — error-correction loops can burn through millions of tokens in a single session
  • The free plan's daily token cap can run out before a complex first build even finishes
  • Real-world cost on large or bug-prone projects can run well above the advertised plan price
  • Less production-hardened out of the box than a more opinionated builder like Lovable

Read the full Firebase Studio review

Firebase Studio was Google's agentic, cloud-based development environment for building and shipping full-stack AI apps — APIs, backends, frontends and mobile — from the browser, with a generous free tier (3 workspaces, no seat fees). As of June 22, 2026, Google disabled new workspace creation and signups, and the platform is scheduled to fully sunset on March 22, 2027, with existing users directed to migrate to Google AI Studio or Google Antigravity. This listing is kept for accurate historical and migration-search context, not as an active recommendation.

Read the full Bolt.new review

Bolt.new (by StackBlitz) runs a full Node.js environment directly in the browser via WebContainers, and its Bolt Agent builds, tests and iterates on a website, web app or mobile prototype from a natural-language prompt. Bolt automatically routes each request to the best-fit model — a Standard tier for general development and a Pro-only Max tier for harder tasks — instead of locking you into one LLM, and claims 98% fewer errors thanks to automatic testing, refactoring and iteration. Generated projects can use React, Next.js, Vue, Svelte, Astro, Angular, SvelteKit, Remix and the wider npm ecosystem, with mobile builds via Expo (instant QR-code preview for iOS/Android). Bolt Cloud bundles the backend — unlimited databases, enterprise-grade auth and user management, SEO optimization and hosting with analytics — plus native integrations with Supabase, GitHub, Stripe and Figma import, and one-click deployment to Netlify. It's used by teams at Google, Microsoft, Salesforce, AWS, Meta, Shopify and others to go from idea to a running, deployable product without local setup.
