Congratulations, Arnaud! I really like the idea of your tool. I was using many tools to track dev productivity in the past – with all kind of charts and plots. Somehow, I never got answer to the question "what do we really spend time on? Is this mostly bug fixing, delivering new features, and how does it affect our KPIs?". I like that Echoes focuses exactly on that.

I've got one question – would it be possible in the future to generate some kind of alerts for the managers when for example the technological debt is growing above some threshold?
