Download the latest release from the GitHub Releases page.\n2. Unzip it anywhere on your computer.\n3. Double-click `modelizer.bat`\n4. Open your browser at http://localhost:8080\n\nThe release includes a tiny local webserver based on miniserve:\nhttps://github.com/svenstaro/miniserve\n\n## Run with Docker\n\nRun the latest published image from Docker Hub:\nhttps://hub.docker.com/r/haanlaurent/modelizer\n\n```bash\ndocker run --rm -p 8080:80 haanlaurent/modelizer:latest\n```\n\nThen open: http://localhost:8080\n\nRun a specific version tag:\n\n```bash\ndocker run --rm -p 8080:80 haanlaurent/modelizer:\u003cversion\u003e\n```\n\nBuild and run locally from this repository:\n\n```bash\ndocker build -t modelizer:local .\ndocker run --rm -p 8080:80 modelizer:local\n```\n\n## Supported modeling elements\n\nModelizer supports:\n- different modeling levels:\n  - conceptual model (CDM)\n  - logical model (LDM)\n  - physical model (PDM)\n- classes\n- associations\n- associative associations\n- reflexive associations\n- composite aggregations (enable in menu first)\n- multiplicities\n- attributes\n- attribute types\n- default values\n- constraints: Null, Unique, Auto Increment\n- import from Java Modelizer files\n\n## What Modelizer does (and does not do)\n\nModelizer is intentionally a teaching tool that simplifies drawing and defining models.\nIt contains no validation logic and does not generate relationships automatically from associations.\nIt does not help you make the \"right\" modeling decisions — you do.\n\n## Export \u0026 storage\n\n- Export format: PNG\n- Models must be downloaded manually (no server-side storage)\n- Settings are stored in browser localStorage\n\n## Acknowledgments\n\n- ChartDB (interface design inspiration): https://github.com/chartdb/chartdb/\n- Java Modelizer by Bob Fisch: https://modelizer.fisch.lu/\n- miniserve (local webserver used in the release bundle): https://github.com/svenstaro/miniserve\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhaan%2Fmodelizer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhaan%2Fmodelizer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhaan%2Fmodelizer/lists"}
