What you may give up
No paid-feature limits established for this edition.
- Self-operated library can render locally or within your website; selfHostable=false records that the library is not a server application.
- Mermaid.ai paid platform has hosted diagram, AI, collaboration and enterprise features; these are not bundled into the MIT library.
Tier A: Scope: MIT text-to-diagram JavaScript library, installable and usable in your own pages; not a standalone collaboration server. All identified library functionality is open. First-party Mermaid Live Editor is linked by official docs. Mermaid Chart / Mermaid.ai commercial editor and collaboration plans are separate from this library. License source
What running it takes
- Local module or CDN delivery
- Browser JavaScript runtime
Hover or focus an icon for its name. Dashed means not established; struck through means no; grouped icons are alternatives.
JavaScript library; embed in local/site pages with browser ESM. No SQL/cache/queue/SMTP/object store required by core renderer. Mermaid.ai cloud collaboration is separate. Infrastructure and staff time are not priced here; this page does not compare total cost.
