In their own words
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.
Eraser
Eraser is a diagramming tool for technical teams that generates diagrams from prompts, code, files, and private Git repositories. It supports flow charts, entity-relationship diagrams, cloud architecture diagrams, sequence diagrams, and BPMN diagrams. Generated diagrams can be adjusted with diagram-as-code or AI edits, and reference libraries can align output with company building blocks. Collaboration includes real-time work, comments, tagging, and unlimited free guests. The service lists GitHub, Notion, Confluence, and a VS Code extension, as well as live diagram embeds and Git-powered updates. The free plan includes 3 files, 3 AI diagrams, and 7-day version history. Starter costs $15 a month when billed annually, or $20 monthly; it adds unlimited files, private files, and API calls. The diagram API is for paid users, while MCP operations are subject to plan AI-credit limits. Eraser says it is SOC 2 Type 2 certified, performs annual penetration testing, and does not train AI models on customer content. Enterprise deployment options include multi-tenant, single-tenant, and self-hosted setups.
