HTML Anything

From the team behind Open Design — 40k★ · 200+ contributors, production-grade and iterating faster. html-anything is the focused agent-era HTML editor; if it clicks for you, Open Design is where the same team ships at scale.

Live page: open-design.ai/html-anything/ — overview, surface modes, and showcase before you clone.

Markdown is the draft. HTML is what humans read. Your local agent writes it. The agentic HTML editor — in the agentic era, you don't hand-edit docs anymore, so the output format should be what the reader actually wants: HTML. Local-first, zero API key, reuses the CLI session you already have logged in — 9 coding-agent CLIs auto-detected on your PATH (Claude Code · Cursor Agent · Codex · Gemini CLI · GitHub Copilot CLI · OpenCode · Qwen Coder · Aider · IBM Bob), driven by 75 composable skill templates across 9 deliverable surfaces (magazine articles · keynote decks · résumés · posters · Xiaohongshu cards · tweet cards · web prototypes · data reports · Hyperframes videos). One-click export to WeChat / X / Zhihu, or download .html / .png.

Showcase

The eight skills that surface at the top of the picker's Featured / 推荐 group — sorted by their recommended: rank in SKILL.md frontmatter (lower = higher). Each ships a real example.html you can open straight from the repo, no auth, no setup.

deck-guizang-editorial · deck · recommended: 1Magazine × e-ink editorial deck, inspired by op7418/guizang-ppt-skill — 10 locked layouts × 5 palettes (Ink / Indigo Porcelain / Forest Ink / Kraft / Dune). Reads like a printed art-zine, not a slide deck.

deck-swiss-international · deck · recommended: 2Swiss International deck — 16-column grid + one saturated accent (Klein Blue / Lemon / Mint / Safety Orange) across 22 locked layouts. Cold, rational, institutional. The deck that reads "a designer made this" the moment it opens.

doc-kami-parchment · doc · recommended: 3Warm-parchment editorial document, inspired by tw93/kami. #f5f4ed ground + ink-blue accent + single serif voice — a noticeably calmer reading surface than plain-white markdown for long essays, reports, and one-pagers.

magazine-poster · poster · recommended: 4Newsprint Sunday-paper poster — oversized serif headline, two-column body, six numbered sections, dot-pattern cream ground. Reads like a printed broadsheet, not a webpage.

video-hyperframes · frame / video · recommended: 5Hyperframes / Remotion-compatible storyboard — 6–10 sequential 1920×1080 frames with hidden duration + transition markers and an auto-play script. Hand straight to heygen-com/hyperframes or Remotion to render .mp4.

frame-glitch-title · frame · recommended: 6Glitch title frame — cyan/magenta chromatic offset, CRT scanlines, corrupted-data subtitle, ASCII noise in the corners. Cyberpunk hero card or video transition.

vfx-text-cursor · vfx · recommended: 7VFX text-cursor opener — a cursor "types" across the canvas, each character revealed with a hot-pink × cyan chromatic trail and directional light leaks. Drop in a quote, get a film-grade opening frame.

frame-logo-outro · frame · recommended: 8Logo outro frame — logo assembles piece-by-piece with glow bloom, tagline rises, CTA appears. The closing card for a product reveal or brand film.

Why this exists

Anthropic's Claude Code team announced they stopped writing internal docs in Markdown — they ship HTML now. The argument is simple:

Markdown	HTML
Good for the writer	Good for the reader
Layout limited to the renderer	Layout is yours
Looks ugly screenshotted into a tweet	Already looks like a designed image
Has to be re-flowed for WeChat / Zhihu / newsletter	One-click format conversion

HTML is the final form for humans. Markdown is just an intermediate state during writing.

But "writing HTML" used to mean writing CSS, picking type scales, snapping to a grid, doing responsive — most users won't, designers won't bother, writers don't have the patience. So what we built: after you press ⌘+Enter, your local AI agent turns any input (Markdown / CSV / Excel / JSON / SQL / raw notes) into a ship-ready single-file HTML in seconds, then one-click sends it to WeChat / X / Zhihu / anywhere. "Ship-ready" is the bar — when generation finishes, the artifact is what your audience actually sees. No "I'll touch it up later" pass.

We stand on four open-source shoulders:

• nexu-io/open-design — the agent-detection layer, the design-system model, and the SKILL.md protocol. next/src/lib/agents/ and next/src/lib/templates/skills/* mirror this architecture directly.
• mdnice/markdown-nice — proof that juice-inlined CSS pastes cleanly into WeChat and Zhihu without per-platform manual fix-up.
• gcui-art/markdown-to-image — the iframe → high-DPI PNG export path.
• alchaincyf/huashu-md-html — the anti-AI-slop discipline that maps into the hard constraints inside every SKILL.md (CJK-first font stack, 8 px baseline grid, contrast ≥ 4.5, must-use-real-data rule).
