html-anything: an agentic HTML editor that transforms raw content into ship-ready designed documents using local coding-agent CLIs

What it solves

HTML Anything is an agentic HTML editor designed to replace Markdown as the final output format for documents. It solves the problem of Markdown's limited layout capabilities and the need for manual formatting when exporting to platforms like WeChat, X (Twitter), or Zhihu. By leveraging local AI agents, it transforms raw input (Markdown, CSV, JSON, SQL, or notes) into professional, ship-ready single-file HTML documents with high-design standards.

How it works

The tool operates as a local-first application that integrates with existing coding-agent CLIs already installed on the user's machine. Instead of requiring a new API key, it reuses the authenticated sessions of agents like Claude Code, Cursor Agent, or Gemini CLI.

Users select from 75 composable skill templates (organized by surface modes such as magazine articles, keynote decks, and web prototypes) and provide their content. The system then streams the agent's output via Server-Sent Events (SSE) into a sandboxed iframe preview, allowing users to watch the page render in real-time. Finally, it provides one-click exports to various social platforms or as standalone HTML/PNG files.

Who it’s for

• Writers and Designers who want high-fidelity, designed documents without writing CSS or managing responsive layouts.
• Developers who want to quickly prototype web pages or create professional reports and data visualizations.
• Content Creators who need to format content for specific social media platforms (e.g., Xiaohongshu, X, WeChat) without manual re-formatting.

Highlights

• Zero API Key Required: Reuses existing local CLI sessions for 8 different coding agents.
• Extensive Template Library: 75 skill templates across 9 surface modes, including keynote decks, Hyperframes video frames, and professional office documents.
• One-Click Export: Specialized export paths for WeChat (CSS inlining), X/Zhihu (high-DPI PNGs or LaTeX placeholders).
• Streaming Render: Real-time preview of the agent's generation process using SSE.
• Format Auto-detect: Supports input in Markdown, CSV, TSV, JSON, and SQL.
