When compared to these tools, GrimoireLab is in general more diverse in terms of **data** sources supported with a common interface: all of them can be retrieved using the Perceval API. For all of them raw and enriched indexes are produced with a similar structure, all of them can be retrieved and analyzed automatically with the same Mordred configuration. Most of the tools mentioned above support one, or a small number, of different **data** sources, and in general are not designed to produce uniform **data** that can be later queried for further analysis in a uniform way. GrimoireLab also provides identity management for all of these **data** sources, and a common way of visualizing and reporting data. However, the main difference is probably the fact that GrimoireLab tools can be used, if needed, in isolation, and that the **data** is stored in a way that allows for many different kinds of further analysis.
