Gaphor vs Horusec

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.

Horusec is a static code analysis tool for identifying security flaws during development. It scans source code and searches project files and Git history for leaked keys and other security issues. The project describes analyzing 18 languages with 20 security tools; listed coverage includes C#, Java, Kotlin, Python, Ruby, Golang, Terraform, JavaScript, TypeScript, Kubernetes, PHP, C, HTML, JSON, Dart, Elixir, Shell, and Nginx. Analysis is configurable through CLI resources. Developers can use its command-line interface, while DevSecOps teams can add it to CI/CD pipelines; a Visual Studio Code extension is also provided. Horusec-Web offers vulnerability dashboards, false-positive controls, authorization tokens, and vulnerability updates. Horusec Platform integrates with the CLI to visualize and manage vulnerabilities, and supports native Horusec, LDAP, and Keycloak authentication. Its repository was archived by its owner on March 19, 2025 and is read-only. Running Horusec with all its tools requires Docker; the platform requires RabbitMQ and PostgreSQL. The open-source plan is free under Apache License 2.0.
