What is it?

HTML Anything is an editor that uses a local AI coding agent to generate HTML from raw input such as Markdown, CSV, JSON, SQL or plain notes. It auto-detects supported CLIs on the PATH, including Claude Code, Codex, Gemini CLI, Cursor Agent, Copilot CLI, OpenCode, Qwen Coder and Aider, and reuses the existing login session, so no separate API key is needed.

Generation is driven by 75 skill templates grouped into nine surfaces: magazine articles, keynote decks, résumés, posters, Xiaohongshu and tweet cards, web prototypes, data reports and Hyperframes video frames. Output is streamed into a sandboxed iframe preview as it is produced, and results can be copied with inlined CSS for WeChat or Zhihu, pasted as images into X, or downloaded as .html or .png.

The project is an Apache-2.0 pnpm workspace built on Next.js 16 and React 19. Adding a skill means adding a folder with a SKILL.md file and an example.html.
