Diagrams.so
Diagrams.so turns written descriptions into editable architecture diagrams, saved in Draw.io format. It generates flowcharts, sequence diagrams, entity relationship diagrams and cloud infrastructure diagrams, with official AWS, Azure, Google Cloud Platform and Kubernetes icon libraries alongside network, database, security and general-purpose shapes. Opinionated Mode can suggest missing components; non-blocking warnings flag risks such as single-AZ deployments and publicly exposed resources. Diagrams export as.drawio XML, PNG or SVG, and.drawio files open in Draw.io, Confluence, VS Code and Notion. Users can import.drawio files on every plan and compare or restore versions using history. The product offers a REST API, MCP server, and Python and TypeScript SDKs, with Claude, Cursor and VS Code listed as MCP clients. Free includes five credits, requires a BYO LLM key and watermarks exports. Free-tier diagrams are public; private diagrams require Pro or Power. Pro costs $10 a year billed annually or $15/mo billed monthly; Power costs $16.67 a year billed annually or $25/mo billed monthly.
