Firecrawl is hiring: 32 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
Strengths
- Supports four LLM providers: Gemini, Anthropic, OpenAI and Groq, chosen via env keys
- Sandbox backend is switchable between Vercel Sandbox and E2B with one variable
- Setup is clone, install, set .env.local, run pnpm dev on port 3000
- MIT licensed
Weaknesses
- Requires a Firecrawl API key; it is listed as required
- Needs a Vercel or E2B account for sandboxes; no local sandbox option documented
- Described as an example app; no docs on deployment, auth or persistence
- No Dockerfile or compose file, and no tagged releases
What it needs
- TypeScript, Gemini, Anthropic, OpenAI, Groq
- Needs Firecrawl API, Vercel Sandbox or E2B, Morph (optional)
- env example file
