Can I use Eraser for free?

Yes. The Free plan allows 3 files, 3 AI diagrams, 7-day version history, and unlimited guests. It's sufficient for personal use or evaluation.

What is 'Diagram-as-code'?

It's Eraser's proprietary DSL that lets you define diagrams in text, enabling version control with Git, programmatic generation via API, and collaborative editing.

How does the MCP server integration work?

Eraser runs an MCP server that allows AI agents (like Claude or Cursor) to perform full CRUD operations on your diagrams using OAuth or API tokens over HTTP or stdio.

What integrations are available?

Core integrations include GitHub, GitLab, VS Code, Notion, and Confluence. Enterprise plans also offer direct connections to AWS, Azure, and Google Cloud for live environment diagrams.

Eraser is SOC 2 Type II certified and penetration-tested annually. Enterprise options include single-tenant or self-hosted deployments for maximum control.

How do 'AI Presets' and 'Rules' improve output?

They allow you to inject team-specific patterns, notation styles, and domain knowledge into the AI prompt, ensuring generated diagrams comply with your internal standards and naming conventions.
