GitUML

UML visualisation
for Git repositories

Understanding new source code
is every programmer's
biggest challenge

GitUML helps programmers understand new code more quickly.

Understand code quickly

Automatically generate diagrams from source code residing in git repositories.

  • UML class diagrams
  • Generate the more powerful Literate Code Map diagrams
  • Upload source code files if you wish

A revolution in documentation

GitUML rapidly produces beautiful UML class diagrams every time.

  • Diagrams automatically update when you push code using git
  • Diagrams are always up to date
  • This let's programmers focus on coding instead of fussing with drawing tools.

contribution of the developer who left the team. Dave Laribee

The GitUML Elevator Pitch

Making software diagramming useful to today's modern, agile, code-centric programmers

  • Easy reverse engineering into UML by simply selecting files from GitHub repositories - file uploads allowed, too.
  • When new code changes are pushed, diagrams are updated automatically thus remain up to date with the code. This maintains diagram accuracy/usefulness and requires less diagram maintenance - saving programmer time.
  • UML diagrams can sometimes be too abstract for programmers to find useful. GitUML supports evolving reverse engineered UML diagrams into Literate Code Maps, which are innovative, powerful "Tuftian" visualisations that empower the programmer to understand complex code, add features and fix bugs more quickly.
  • Literate Code Maps combine class and sequence diagrams into the one diagram, with numbered steps which lead the reader's eye, step by step, through the diagram. Each diagram box (which can be a class, file or any container) can contain one or more code compartments where you can add real source code fragments and rich narrative commentary. See the Literate Code Map manifesto for more information.
  • Easy to share rich, zoomable diagrams via urls.
  • Using textual PlantUML markup for flexible diagram editing rather than $$ and fiddly tools. Each GitUML diagrams is built from a blend of both automated reverse engineering and additional custom diagram markup.
  • GitUML is appealling to organisations who understand that powerful, insightful, diagrams containing rich detail are a boon to new programmers joining a team, increasing productivity thus reducing new staff onboarding times. They can capture knowledge when programmers leave a project, too.
  • The process of building a Code Map is based on what many programmers already do when taking notes in their notebooks and reading code. The process of building a Code Map will give a programmer understanding of any complex software behaviour, which empowers the programmer to add features and gets bugs fixed more quickly.
  • Consulting services available to facilitate the use of GitUML in your organisation. Custom hosting for sensitive, non GitHub codebases available.
GitUML is a nice project!

Point and Click

Browse any git repository on the web and select the files you want to visualise.

  • Popular public repositories listed
  • Browse your own repositories
  • Automatic layout - saving you time

Gallery View

Access your diagrams via a thumbnail gallery.

  • Click to edit or delete, duplicate etc
  • View descriptions and user comments
  • Search by repository or tags

Building a UML or Literate Code Map diagram as part of code analysis results in real understanding plus a knowledge artifact (the diagram) to keep and share.

Keep diagrams simple

Communicate what's important

  • Select only the files and classes that you want
  • Capture knowledge
  • Each diagram tells a story, your way

Refine your diagrams

Add anything you want to your diagrams

  • Attach yellow text notes to any class
  • Add additional classes & relationships
  • Use "point and click" to add common elements or use PlantUML markup
  • Evolve your reverse engineered UML diagram into a powerful Literate Code Map diagram containing source code fragments and much more. Blend automatic with custom diagram elements.

Losing staff who "know the code"
is every company's fear

GitUML protects your intellectul property when staff turnover occurs.

Productive Handovers

Developers with knowledge can document designs rapidly before they leave

  • Preserve knowledge of the code
  • Offboard existing staff with more confidence.
  • Onboard new staff more quickly - saving you money
The total cost of losing an employee can range from tens of thousands of dollars to
1.5 to 2 times their annual salary. Rachel Ferrigno

Unplanned turnover hurts — especially when you lose top people. Aaron Reed

Share your diagrams

Diagrams are URLs

  • Each diagram is a permalink URL internet resource.
  • Share diagrams with your team, in print, blogs and documentation.
  • Turn off GitUML git push auto update to lock a diagram to a moment in time.

Attract contributors

Get more contributors to Open Source projects. Contribute more.

  • Key design diagrams of Github projects helps everyone.
  • Attract more contributors by making it easier for them to understand the code.
  • Contribute more productively to well documented projects.

Language Support Roadmap

GitUML can reverse-engineer the source code into UML diagrams of the following languages

  • Python
  • Java
  • Javascript
  • Delphi/Free Pascal
  • C# - (early 2020).
  • HTML - into literate code map boxes - (mid 2020).
  • Kotlin - (late 2020).

Note: GitUML can automatically detect and reverse engineer both Python 3 and Python 2



GitUML reverse-engineers any Python or Java source code!

GitUML can also reverse engineer Delphi/Free Pascal and Javascript.


Build Literate Code Map diagrams

When you want more detail than a UML diagram can provide try building a Literate Code Map which is a new, practical evolution of UML for today's code centric, practical programmer. Blend reverse engineering (via GitUML) with your "literate" custom code fragments and rich, text narrative comments/stories - step by step so that viewers of the diagram follow the use case story.
