FIG-002 / OVERVIEW

at a glance.

Compare Tiptap and @humanspeak/svelte-markdown: a ProseMirror rich text editor versus a focused Svelte 5 markdown renderer for display-only content.

FIG-003 / FEATURE MATRIX

side-by-side.

Every surface that matters, compared without spin.

feature	@humanspeak/svelte-markdown	Tiptap
Svelte 5 Native	yes	Via wrapper (svelte-tiptap)
TypeScript Support	yes	yes
Markdown Rendering	yes	Via extension
WYSIWYG Editing	no	yes
Bundle Size	Lightweight (~15KB)	Heavy (~200KB+ with extensions)
Custom Renderers	yes	Via node views
Token Caching	yes	no
LLM Streaming Mode Tiptap can update editor state live, but it does not document a dedicated markdown streaming renderer mode.	writeChunk() / resetStream()	no
Streaming HTML Output Tiptap is a content editor — rendering agent-streamed HTML where partial <div>...</div> blocks resolve mid-stream is outside its model.	Partial blocks reconcile when </tag> arrives	no
HTML Tag Control	84 tags with allow/deny	Via schema
Collaborative Editing	no	yes
Toolbar/Menus	no	Headless (build your own)
Setup Complexity	Minimal — one component	Significant configuration

FIG-004 / STRENGTHS

where each shines.

▣ svelte markdown 12

+Svelte 5 runes-native — built for runes, not retrofitted
+TypeScript-first with full type safety
+Built-in token caching (50-200x faster re-renders on repeated content)
+LLM streaming with imperative writeChunk() / resetStream() API
+23 markdown renderers + 84 HTML tag renderers — every override is a Svelte snippet
+First-class extensions: KaTeX math, Mermaid diagrams, GitHub alerts, footnotes
+Built-in XSS protection — protocol allowlist, event-handler stripping, attribute sanitization
+Allow/deny utilities (allowHtmlOnly, excludeRenderersOnly, etc.) for fine-grained control
+Drop-in component — works anywhere in your Svelte app
+Fraction of the bundle size
+Zero configuration — just pass markdown and render
+Purpose-built for rendering, not editing

▢ tiptap 5

+Full WYSIWYG rich text editing experience
+Massive ecosystem (~36,500 GitHub stars)
+Collaborative editing support (Y.js)
+Extensible with 100+ official extensions
+Framework-agnostic — works beyond Svelte

FIG-005 / LIMITATIONS

where each falls short.

▣ svelte markdown 4

−Smaller community (newer project)
−Runtime-only (no build-time optimization)
−No editing capabilities
−No collaborative features

▢ tiptap 4

−Massive bundle size for simple rendering use cases
−Svelte support is via community wrapper, not first-party
−Complex setup and configuration for basic markdown display
−Overkill if you just need to render markdown

FIG-006 / VERDICT

the honest call.

Choose Tiptap when you need a rich text editor with WYSIWYG capabilities, collaborative editing, or complex content authoring. Choose @humanspeak/svelte-markdown when you need to display markdown content — it is dramatically simpler, smaller, and faster for pure rendering.
