| Spec score · UML Modeling Software | 9.0 (#1) | 8.3 (#3) |
| Deployment | Generated Docker components can be used to automatically deploy a running application from a model. | The architecture is client-server with Microsoft SQL Server and can run on-premise, in AWS, in Azure or in another customer cloud. |
| Documentation | ReadTheDocs covers installation, tutorials, B-UML, generators, API reference, troubleshooting, contributor setup and release notes. | Installation, administration and REST API guidance is provided through a dedicated online manual and downloadable installation material. |
| Headquarters | Belval, Esch-sur-Alzette, Luxembourg | Berlin, Germany |
| Integrations | Documented generation targets include Python, FastAPI, Django, SQLAlchemy, SQL, Java, React, PyTorch and TensorFlow. | Official interfaces cover Active Directory, Jira, Azure DevOps, ReqIF, Microsoft Word, Excel, Project, Visio, Outlook, Visual Studio Code and standard XML/XMI/XPS/CSV/PDF formats. |
| REST API | The REST generator creates FastAPI services with selectable GET, POST, PUT, PATCH and DELETE methods. | A REST API supports reading, creating and editing data and allows custom JSON schemas for exchange. |
| Support | The project offers an on-page assistant without an account, email support, and GitHub bug triage weekly. | Maintenance includes installation and usage support, reproducible bug fixes and weekday telephone or email support from Berlin in German or English. |
| System requirements | Current documentation tests Python 3.11 and 3.12; local editor development additionally needs Git, Docker and Node.js 20 or newer. | The server requires Windows Server 2016 or newer, .NET Framework 4.8, SQL Server 2016/2019/2022/2025, quad-core CPU and at least 8 GB RAM; the client requires Windows 10 or newer and .NET 4.8. |
| What it does | BESSER is an open-source low-code platform that turns models into APIs, databases, agents and deployment artifacts. | objectiF RPM combines requirements engineering, project management, testing, risk management and lifecycle traceability in one system. |

In their own words
BESSER
BESSER is an open-source low-code platform for building smart applications by modeling once and generating APIs, databases, agents, and deployments. Its 15+ generators cover databases, REST APIs, web apps, AI agents, and deployment manifests. Built-in modeling includes class diagrams, state machines, object diagrams, agents, and deployment specifications. The GUI Creator deterministically generates complete React frontends from platform-independent GUI models, and AI-assisted modeling supports software with embedded AI components. BESSER connects through an MCP server to Claude Desktop, Cursor, and other MCP-aware clients; BESSER Skills also integrate with Claude Code, Cursor, and Copilot for model and code-generation workflows. Generated Docker components can be used to deploy a running application from a model. The project is MIT-licensed and free, with no freemium tier or hidden fees. It runs on the web, Linux, macOS, and Windows. The Python package installs with pip, and the full codebase can run locally for extensions and generators. It is tested on Python 3.10, 3.11, and 3.12; Python 3.13 is not supported yet. Support includes an on-page assistant, email, and weekly GitHub bug triage.
