BridgePoint vs Gaphor

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.

Gaphor is a desktop modeling application for visualizing and documenting applications and systems with UML, SysML, RAAML, and C4. It implements a UML 2 data model and the UML, SysML, and RAAML OMG standards, and supports the C4 model. Its diagram options include Class, Interaction, State Machine, Block Definition, and Requirements diagrams, with diagram items that can be mixed and styled through a built-in engine. Diagrams export to SVG, PNG, PDF, or EPS, including batch export for every diagram in a model. Gaphor can also create a static, interactive, read-only HTML model report that needs no server or backend. As a Python library, it can inspect, generate, or update models through scripts or Jupyter notebooks; a Sphinx extension embeds diagrams in reStructuredText or Markdown documentation. The software is free under the Apache 2 license for Windows, macOS, and Linux. Windows users have installer, portable, and Winget options; macOS requires version 10.15 or newer.
