In their own words
Eraser
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.
Software Ideas Modeler
Software Ideas Modeler is a CASE tool for designing software and processes with diagrams. It supports more than 110 diagram types, including UML, BPMN, SysML, ERD, and flowcharts. A project keeps diagram elements in a connected model, so an element can appear in several diagrams and edits carry across them. The software can generate and parse source code, reverse engineer code into models, and create SQL creation and change scripts from ER diagrams. Editions range from basic diagrams to documentation and diagram generation, project comparison, cooperation tools, and model versioning. Ultimate lists AI support through the OpenAI API; SVN and XMI import and export are also supported. It can work offline except for downloading, obtaining a license key, and internet-dependent features such as AI tools. Setup and portable packages are available for x64, x86, and Arm64. The maker is based in Bratislava, Slovakia, and was founded in 2009. The product has a free plan for non-commercial use and a 30-day trial.
