Bolt.new alternatives: 3 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
El mismo ciclo de prompt a app en un sandbox en la nube, impulsado por tus propias claves de modelo.
licenseMIT
runsyour machine or their cloud
installClone the repo, install with pnpm, add service keys to .env and run the Next.js development server
enginesGemini, Anthropic, OpenAI or Groq; Firecrawl for extraction; Vercel or E2B sandboxes; optional Morph
dataGenerated React source lives in the selected cloud sandbox; local configuration is in .env, and prompts or site content go to the selected services
the catch vs Bolt.newIt is a developer-run example requiring several service keys, without Bolt's managed account, persistent workspace and integrated deploy experience.
setupSeveral model, extraction and sandbox service keys are needed before the complete workflow works

Constructor visual de código abierto sobre una base de código real de React; el hermano mayor del sandbox del navegador.
licenseApache-2.0
runsyour machine or their cloud
installHosted signup, or self-host with Bun or Docker plus Supabase configuration
enginesOpenRouter plus configurable code-edit services such as Morph or Relace
dataProject code lives in the workspace or sandbox; application metadata and assets use the configured Supabase instance
the catch vs Bolt.newIt is narrower and more design-first, with less mature prompt-to-full-stack generation and deployment than Bolt's browser workspace.
setupHosted access may be gated; self-hosting needs Bun or Docker, Supabase and several environment variables

runson your machine
installDesktop installer
enginesOpenAI, Anthropic, Google Gemini, OpenRouter-compatible providers and local Ollama
dataGenerated project source and app metadata stay on the computer; prompts and selected context go to the chosen provider unless a local model is used
the catch vs Bolt.newIt has no managed browser sandbox, instant public hosting or one-click deployment comparable to Bolt, so you own the local environment and deployment.
setupA model-provider API key or a separately installed and configured local Ollama model

bolt.diyMIT source, but its WebContainers runtime needs a commercial licence for production business use.

La gente sigue pagando por Bolt.new porque la interfaz se puede copiar, pero el producto son los modelos de código de alta calidad, la clasificación de contexto, la ejecución segura y la evaluación constante. El costo recurrente cubre los cambios de modelos, la indexación, la inyección de indicaciones, los permisos de herramientas, el uso de entornos de prueba, la evaluación, las decisiones de telemetría y la compatibilidad con IDE, no solo la interfaz visible. If none of that applies to you, any pick above saves $300 a year.
Is there a free alternative to Bolt.new?
Yes: open-lovable, Onlook, Dyad. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Bolt.new?
Our verdict is NO TANTO. Es posible hacer una versión de consuelo, pero el valor decisivo del producto de pago está fuera de una reconstrucción individual. Para Bolt.new, genera y edita un proyecto web pequeño en un entorno de pruebas local a partir de indicaciones estructuradas. El límite difícil es el entorno de pruebas del navegador, la orquestación de modelos, la ejecución de paquetes, el despliegue y el cómputo alojado, además de los modelos de última generación, la infraestructura de contexto y la seguridad de ejecución. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/bolt-new.
