About

Mermaid Chart is a diagramming application that turns text, Markdown-style syntax, or natural-language prompts into rendered diagrams. It supports flowcharts, sequence diagrams, Gantt charts, ER diagrams, timelines, mind maps, org charts, state diagrams, Git graphs, user journeys, class diagrams, pie charts, quadrant charts, and block diagrams.

The product includes a visual editor, AI-assisted creation, code-based editing, real-time collaboration, plugin integrations, and VS Code support. It is aimed at developers, technical writers, analysts, educators, and other teams that need to create and share diagrams in documentation, presentations, and internal workflows.

Free Tier Value

Credit card Required
Feature parity 50%

The provided page text does not expose any concrete free-tier caps, credit amount, or trial duration, so a conservative free-tier value cannot be computed from the page. The page does show a sign-up flow and a contact-sales path, but no explicit no-credit-card claim. Because the listing_type is already given as free_tier and the page suggests meaningful product features are available behind the paid offering, I set feature parity to 50 and leave free_tier_value_usd_per_month null.
