Welcome to the Alambic project
Alambic is an open-source platform and service for the management and visualisation of software engineering data.
It basically retrieves data from various repositories (code metrics, scm metadata, stack overflow questions, etc.) and makes them available for custom plugins to produce analysis, numbers, graphics, and data sets.
A flexible plugin system allows to easily add new data sources (e.g. git or svn logs, bugzilla queries), analysis tools (including R scripts), visualisation and reporting (e.g. knitr or plotly graphs). Examples of plugins ready to use include PMD Results Analysis, StackOverflow questions and PMI Checks for Eclipse projects.
Check the complete list of plugins in the Plugins section.
Measures are aggregated in a tree-like quality model structure to better organise and understand the information. The Quality Model can be entirely customised, and almost any type of data source can be added through plugins.
