presentation-md vs frontend-slides — structured proofs vs prompt packs

Side-by-side

Criterion	presentation-md	frontend-slides
Where it runs	Claude Code, Cursor, Copilot, Codex, Gemini CLI + MCP	Agent prompt packs + HTML template gallery
Authoring model	✓ Typed Deck JSON schema (14 layouts incl. `chart` + `custom-html`)	Freeform / template-guided HTML from prompts
Theme proofs	✓ 75 schema-validated structured proofs	Showcase HTML templates (discovery-first)
Live theme preview	✓ `preview_themes` MCP (title + layouts bake)	✓ Strong live style gallery UX
Design craft	Asymmetric ratios, emphasis, bento, image-heroes, surfaces	Bold visual systems; agent writes full HTML
PowerPoint	✓ Native PPTX export + import round-trip + speaker notes	✗ HTML-first; no first-class PPTX pipeline
Browser Studio	✓ Hosted Studio with craft controls	✗ No equivalent editor product
MCP tools	✓ 9 typed tools (render, export, audit, themes, brand, import…)	Skill / prompt workflow, not a typed MCP product
Brand import	✓ CSS / URL → contrast-safe theme package	Manual template restyle
Output ownership	Self-contained HTML you own + optional PPTX	Self-contained HTML you own
License / price	✓ Free, MIT, no account	✓ Open-source skill / templates

Where frontend-slides is stronger

Discovery UX that made “pick a vibe first” feel obvious
Fully freeform multi-page HTML when you abandon schema on purpose (we keep custom-html for one-off art inside Deck JSON)
Community momentum as the reference for bold agent slide aesthetics

Where presentation-md is stronger

Schema-validated Deck JSON — reproducible, auditable agent output
75 structured theme proofs with craft surfaces, not only showcase HTML
Native PPTX export/import with speaker notes — opens in PowerPoint, Keynote, Google Slides
Browser Studio + 9 MCP tools for agents that need a product, not only a prompt
Brand import with contrast guards so muted copy stays readable

Verdict

Use frontend-slides when you want maximum HTML freedom and gallery energy. Use presentation-md when the deck must survive re-theme, audit, PPTX handoff, and agent loops — same discovery energy, plus the structured layer competitors cannot match.
