Firecrawl is hiring: 33 open roles
Overview
Next.js app where you describe a React app in chat and an LLM generates and edits the code inside a remote sandbox (Vercel Sandbox by default, or E2B). It uses the Firecrawl API to scrape existing sites as reference material. The LLM can be Gemini, Anthropic, OpenAI or Groq, with optional Morph for faster edit application.
Who it is for: Developers who want a self-run prompt-to-React app builder to study or fork
Ranked among open-source alternatives to Lovable (#9 of 10), v0 (#9 of 10), Bolt.new (#7 of 10) and Replit (#7 of 10).
Strengths

- Sandbox backend is switchable between Vercel Sandbox and E2B with one variable

- MIT licensed
