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 cloud-based diagramming tool for mapping processes, planning teams, and visualizing technical systems. It supports process maps, flowcharts, organization and team planning, technical diagrams, and systems and architecture visuals. Lucid AI can use text prompts to add content to the canvas and answer questions. Users can link Google Sheets, Excel, or CSV files to create visualizations from data, and collaborate in real time or asynchronously. Its marketplace lists integrations including Jira, Confluence, Slack, Microsoft Teams, Notion, AWS, and Azure. The public API supports creating, reading, and updating Lucidchart and Lucidspark documents. The Free plan costs nothing and includes three editable Lucidchart documents, up to 60 shapes per document, and 100 basic templates. Individual costs $9 a month and adds unlimited documents, shapes, and lines, premium templates and shape libraries, Presentation Mode, 1 GB cloud storage, and Visio import and export. It is available on Android, iOS, web, and as an extension; there is no desktop app. Lucid lists a free plan and a seven-day trial.
