Eraser vs Lucidchart

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.

Lucidchart is a web, iOS, and Android diagramming tool with real-time collaboration and offline editing. It supports process maps, flowcharts, organizational charts, technical and system architecture diagrams, UML diagrams, ERDs, sequence diagrams, Gantt charts, and C4 models. Users can import VSDX, VSD, VDX, Draw.io XML, OmniGraffle flat files, BPMN, and XPDL, then export PDF, PNG, JPEG, SVG, VDX, VSDX, JSON, or CSV. AI can create diagram content from text prompts, and UML markup can generate sequence diagrams from text. Google Sheets, Excel, and CSV data can link to visualizations; conditional formatting highlights patterns, while layers manage visibility and hierarchy. Lucidchart offers more than 100 custom-built integrations and a free signup. The Free plan costs nothing for Basic diagramming access. Individual, Team, and Enterprise plans are listed without prices. Lucidchart is associated with Lucid Software Inc., founded in 2010 and headquartered in South Jordan, Utah.
