Master Eraser with our step-by-step tutorial, detailed feature walkthrough, and expert tips.
Explore the key features that make Eraser powerful for diagramming & docs workflows.
Eraser is best used for technical design work where diagrams and documentation need to stay editable over time. Its strongest workflows include architecture diagrams, data flow diagrams, sequence diagrams, ERDs, API diagrams, Kubernetes architecture, CI/CD diagrams, threat modeling, and design docs. Because it combines an infinite canvas with Markdown notes and diagram-as-code, it works well for engineering teams that want visual context and written decisions in the same place.
Yes. Eraser’s Free plan is listed at $0 per member per month and includes 3 files, 7-day version history, unlimited guests, diagram-as-code, Markdown notes, and GitHub, Notion, Confluence, and VS Code integration. The pricing table lists 3 AI diagrams, while the FAQ text on the same pricing page says free teams can generate up to 5 AI diagrams or edits, so buyers should confirm the current limit before relying on the free tier for a workflow.
Eraser’s Starter plan costs $15 per member per month when billed annually or $20 monthly. It includes unlimited files, 40 AI diagrams, 90-day version history, private files, 20 custom icons, API calls, and everything in Free. The Business plan costs $45 per member per month annually or $60 monthly and adds 250 AI diagrams, unlimited version history, SAML SSO, 100 custom icons, reference diagrams, and everything in Starter. Enterprise is custom priced.
Eraser AI diagrams are created from prompts and can then be edited either manually through diagram-as-code or with additional AI edits. This is important because architecture and system diagrams usually need iteration: names change, services are added, and relationships need to be corrected after review. Instead of producing a static image, Eraser keeps the diagram in an editable structure that engineers can continue refining.
Eraser is narrower and more engineering-focused than Lucidchart, Miro, or Figma. Lucidchart is stronger for broad enterprise diagramming libraries, Miro is stronger for workshops and facilitation, and Figma is stronger for high-fidelity product design. Eraser is the better fit when the output is a technical design doc, architecture diagram, ERD, API diagram, or cloud topology that should live near GitHub, Confluence, Notion, or VS Code.
Now that you know how to use Eraser, it's time to put this knowledge into practice.
