How the 6.6 was reached
- Quality of output6/10
About 9,000 GitHub stars and active Apache-2.0 project, but quality claims and 75 templates are vendor-described only; no benchmarks or independent reviews. github.com
- Ease of use7/10
Local-first, no API key, auto-detects nine agent CLIs on PATH; but no docs page found and it needs an existing agent CLI installed. github.com
- Pricing value9/10
Apache-2.0 open source and free to use with no new account or API key; user's existing agent CLI subscription is the only dependency. github.com
- API and integration quality5/10
Many input formats and one-click export to WeChat, X, Zhihu and standalone HTML or PNG; no documented API or SDK found, and docs page was not found. open-design.ai
- Solves the problem it claims to solve6/10
Delivers Markdown/CSV/JSON to publish-ready HTML via templates per vendor; adoption of about 9,000 stars supports it, but no independent verification of results. github.com

Pros & Cons
Pros
- Free and Apache-2.0 licensed, so templates can be forked and modified
- No separate API key or subscription if you already use a supported agent CLI
- Skills are plain SKILL.md folders, which makes them easy to read and customize
- Export targets cover Chinese social platforms that many tools skip
Cons
- Requires an authenticated coding-agent CLI, so model costs come from that agent's own plan
- Output quality depends on the underlying agent and the chosen skill
- Export presets lean toward WeChat, Zhihu and Xiaohongshu, which may matter less outside China
- Young project from the OpenDesign family with limited independent reviews
HTML Anything suits people who already pay for a coding agent such as Claude Code or Codex and want to turn notes and data into formatted pages without another subscription. The skill-folder design is easy to inspect and change. Results will track the agent you plug in, and the export presets favor Chinese publishing channels.
