Frequently Asked Questions

Is there a free version of Eraser?

Yes. Eraser offers a permanent free plan that includes a limited number of files and AI diagram generations per month, plus seven-day version history and unlimited guest access — no credit card required.

What types of diagrams can Eraser create?

Eraser supports cloud architecture diagrams, entity relationship (ER) diagrams, flowcharts, sequence diagrams, and BPMN diagrams. All of these can be generated from plain-text prompts via DiagramGPT or drawn manually on the canvas.

How does Eraser integrate with GitHub?

Eraser's Eraserbot connects to your GitHub repository and can automatically generate architecture and codebase diagrams that stay up to date as your code changes. You can also embed and edit diagrams directly inside README files.

Is Eraser suitable for enterprise teams with security requirements?

Yes. Eraser is SOC 2 Type 2 certified and offers SAML SSO on its Business and Enterprise plans. Enterprise customers can also opt for single-tenant or private cloud deployments for additional data isolation.

How steep is the learning curve for new users?

Eraser is designed with a minimal UI and a command palette to keep the experience approachable. Engineers already familiar with Markdown and GitHub will feel at home quickly, and the AI features reduce the need to learn complex diagram syntax.
