Core Technology Stack

Open Lovable integrates several key components:

• Firecrawl – powerful web crawling engine that supports JavaScript-rendered websites.
• Kimi AI models (via Groq / Moonshot AI) – interpret site structures and generate React code.
• E2B Sandbox – runs generated code in an isolated environment for safety.

Together, these components form a pipeline of crawl → understand → generate → safely execute.

Community Feedback

On Hacker News, some users noted that Open Lovable is essentially a “website copier,” raising ethical discussions around its use of Firecrawl for scraping. Still, it has been praised as a powerful prototyping and learning tool.
