Eraser review
A flexible diagram-as-code workspace for technical teams building with AI.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Eraser is a collaborative diagramming and documentation tool for engineering and technical teams. It combines AI diagram generation with diagram-as-code through Eraser DSL, supporting cloud architecture, flow charts, entity relationship, sequence, and BPMN diagrams. The workspace includes an infinite canvas for diagrams and Markdown notes, along with real-time collaboration, commenting, tagging, and version restore. It is best suited to teams that want diagrams connected to technical documentation and developer workflows.
The plan structure covers individual and team use. The Free plan provides 3 files, 3 AI diagrams, 7-day version history, unlimited guests, diagram-as-code, and Markdown notes. Starter costs $15 per member per month when billed annually and adds unlimited files, 40 AI diagrams, 90-day version history, private files, 20 custom icons, and API calls. Business costs $45 per member per month when billed annually, with 250 AI diagrams, unlimited version history, SAML SSO, 100 custom icons, and reference diagrams. Enterprise adds unlimited AI diagrams and version history, flexible deployments, a customer success manager, and usage reporting.
Eraser’s strongest fit is its connection to developer ecosystems. GitHub, Notion, Confluence, and VS Code integrations sit alongside a REST API and MCP server for diagram creation and management. Import support includes images, Markdown, HTML, draw.io, and Eraser content, while exports include PNG, SVG, PDF, BPMN, Visio, draw.io, and Markdown. These options help technical teams move diagrams between documentation, development, and presentation contexts. Teams seeking AI-assisted, collaborative, code-oriented diagramming should consider Eraser; those needing a simpler general-purpose canvas may find its technical focus less relevant.
