HTML Anything – Agent‑centric HTML editor

What it is – A local‑first, zero‑API‑key web app that lets you write in any plain‑text format (Markdown, CSV, JSON, SQL, etc.) and have a local AI coding‑agent turn it into a complete, single‑file HTML page. The generated page is instantly previewed, can be exported as HTML or high‑DPI PNG, and shipped directly to Chinese social platforms (WeChat, X, Zhihu) or saved locally.

Key capabilities

• Agent detection – On startup the app scans your PATH for up to 9 supported coding‑agent CLIs (Claude Code, Cursor Agent, OpenAI Codex, Gemini CLI, GitHub Copilot CLI, OpenCode, Qwen Coder, Aider, IBM Bob) and lets you pick which one to run.
• 75 ready‑made skill templates – Organized into 9 surface modes (magazine article, keynote deck, résumé, poster, Xiaohongshu card, tweet card, web prototype, data report, Hyperframes video). Each skill defines a layout, palette, and content structure; the agent fills it with your input.
• Live streaming render – The agent streams JSON‑line output; the front‑end parses deltas and updates an isolated <iframe> preview in real time, so you watch the page build line‑by‑line.
• One‑click export – Inline‑CSS “juice” for WeChat, screenshot‑to‑PNG for X/Weibo/Xiaohongshu, LaTeX placeholder handling for Zhihu, plus plain .html and .png downloads.
• Sandboxed preview – The iframe runs with `sandbox=
