The Green Metrics Tool is a free open-source (FOSS) tool we designed as a concept on how we believe it can support developers best to measure the energy / CO2 consumption of software architectures.
Our tool is open-source AGPLv3 Licensed
You can either install it locally or use our demo dashboard, where we also offer the possibilty to submit software for measuring (link below).
Please see all the details on Github and in the documentation.
