Open-source alternative to Claude Artifacts for every coding agent. Any agent ships a self-contained page or app to a live URL — Claude Code, Cursor, Codex, Cline, any harness — then you review in the browser and it fixes. Self-hosted, $0 on Cloudflare's free tier. Maintained by plivo-labs on GitHub, where it has earned 20 stars from the community.

It's actively developed around agent-agnostic, ai-agents, aider, and is a solid reference for anyone building with these tools.
