draw.io vs Eraser

draw.io is a free, open-source diagramming tool for creating visual layouts, from flow charts and mind maps to network, architecture, UML, BPMN and floor-plan diagrams. It supports real-time collaboration, and files can be opened and edited across platforms. Users can choose their own storage or save locally with the desktop app; draw.io says it cannot access users' data. No sign-up or credit card is required to start diagramming, and the desktop app is free forever. Diagrams can remain editable or be exported to SVG, PNG or PDF. Supported imports include draw.io, XML, Gliffy, VSDX, Lucidchart, PNG, SVG and JPEG. Integrations include Google, Microsoft, Atlassian, GitHub, VS Code, Notion and Chrome. Interactive diagrams can be embedded in documents, wikis or applications. The listed platforms are web, Windows, macOS, Linux, iOS and Android. Support is available through GitHub Discussions and Stack Overflow. The site says there is no Enterprise tier for SSO.

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.
