Pixela

Pixela is the API service. With this service, you can get a GitHub like graph that expresses the degree of your daily various activities on a basis with a vivid gradation. All operations are performed by API. And, it’s free.

Pixela provides almost all the features for free, but some features are only available to those who pay for Pixela by Patreon.
And the logo/icon sponsors are supporting a little more than that.

Pixela supports people around the world in their efforts and continuity.
If you or your company support it, how about supporting Pixela?
