BridgePoint vs kUML

BridgePoint is a desktop tool suite for UML model editing, simulated execution, and translation in model-driven development. Built on Eclipse, it combines an editor, the Verifier, and model compilers. The Verifier runs and debugs models with stack tracing, variable views, stepping, and breakpoints. Compilers translate models into implementation languages such as C or SystemC and can conform to standards including IP-XACT, AUTOSAR, and MISRA-C. Modeling constructs provide ways to connect models to existing code and libraries. The Editor, Verifier, and Model Compilers are available under the Apache 2.0 license at no cost. Installable zip builds include the Eclipse and BridgePoint environment, so no prior software is required. BridgePoint supports Windows, macOS, and Linux, and includes class, component, state machine, interaction, activity, use case, sequence, and communication or collaboration diagram types. Nightly builds contain the newest code but are described as the least tested engineering delivery. Production projects can obtain BridgePoint Pro releases and support through a Service Pro contract.

kUML is a modeling tool that expresses UML 2.x, SysML 2, C4, BPMN 2.0, and ERM as a type-safe Kotlin DSL. It supports all 14 UML 2.x diagram types, with compile-time validation and IDE support. Built-in transformations generate JPA, OpenAPI 3.0 YAML, Kubernetes manifests, and Dockerfiles. Integrations include CLI, Gradle, IntelliJ, Obsidian, Asciidoctor, and VS Code. For interoperability, it supports Structurizr DSL round-tripping and optional XMI through the kuml-io-emf module. kUML also includes an MCP server for agent introspection and a kuml ai subcommand for AI-assisted modeling. It is free and open source under Apache 2.0, with no paid plans or feature limits stated. It runs on Windows, macOS, Linux, and the web, and can be deployed both self-hosted and through other means. Install options include packages for major desktop systems, Docker, and Maven Central library modules. Rendering Kotlin scripts executes their source code, so use only scripts or workspaces you trust.
