What flow-chart.io is

flow-chart.io turns written descriptions, documents, and repository context into editable diagrams for software engineers, architects, and IT professionals. Its 17 supported diagram domains include BPMN-inspired processes, C4, UML, cloud architecture, ERDs, threat models, DevOps pipelines, networks, and org charts. Diagrams use editable nodes, connectors, labels, and lanes, and users can refine them by chat or browse, compare, and restore earlier versions. A GitHub connection can scan a repository codebase to ground a diagram in the system it describes. Exports include SVG, PNG, PDF, JSON, and Mermaid. Image conversion can reconstruct supported raster images as editable objects, but outcomes vary with image quality and complexity and need review. Standards checks and the AI audit advisor offer suggestions, not certification; the full audit suite is in Pro and Team. The free plan costs nothing, with up to 3 saved projects and credits for about five standard diagrams, without a credit card. Pro is $19 a month; Team is $29 a month billed from $29/seat/month; Suite is $49 a month. It is web-based and lists a REST API and MCP server.
