Eraser vs Visual Paradigm

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.

Visual Paradigm is a visual modeling and development platform covering diagramming, code engineering, agile management, and enterprise architecture. It supports UML, SysML, flowcharts, organization charts, ER, BPMN, data-flow, EPC, mind maps, C4, Gantt, wireframes, and cloud architecture diagrams. AI can generate class diagrams, flowcharts, and user stories from descriptions, while the Unified Platform provides access to more than 100 specialized apps. Users can work across the desktop application and external web browsers, with project synchronization between them. Visual Paradigm Cloud supports concurrent design, review, and commenting. Listed online collaboration limits are three participants for Free, five for Starter, and unlimited for higher plans. Integrations include Jira, Confluence, Eclipse, NetBeans, IntelliJ IDEA, Visual Studio, and Android Studio. The Free plan is strictly for non-commercial use and includes more than 40 AI-powered apps and basic diagramming. Starter costs $4 a month billed annually; desktop subscriptions start with Modeler at $6 a month billed monthly. A 30-day trial is available.
