Open-source AI agent that builds websites
Category: Code & Development. Pricing: free. Last modified: 2026-09-07.
Open-source agentic website builder by Peter Steinberger that exploded after his Lex Fridman appearance in early 2026. Prompt it once and it spins up a working site, no IDE required. Powerful, but treat it with caution: high-severity RCE vulnerabilities (e.g. CVE-2026-25253) and thousands of unpatched public instances mean self-hosters MUST keep it updated and never expose dev installs to the open internet.
