In their own words
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.
