Surf.new

Category: OSS Agent

Surf.new is an open-source web agent playground built by the Steel.dev team. It is described as an open-source alternative to OpenAI Operator. The app lets you test multiple AI web agents (Claude, GPT-4, Gemini, Fireworks, and others) controlling a real cloud browser powered by Steel.dev. Agents can navigate, click, fill forms, and scrape pages just as a human would, while a live browser-stream view shows what the agent sees.

The stack is Next.js 15 (frontend) + FastAPI (Python backend) + Steel SDK (cloud browser) + Langchain (agent framework) + Vercel AI SDK (chat interface).
