It took me a while to understand what your tool is doing. It looks like an abstraction layer for concrete monitoring/alerting solutions.
What confuses me is:
- You introduce Keep like this "Think of Keep as Prometheus Alertmanager but for all observability tools", but then there is no Alertmanager provider. Is this planned?
- You mention that you support the 3 hyperscaler clouds (AWS, ...), yet I do not see any examples or code that backs this up
- You mention that Keep can be used to _test_ alerts. How? Examples? Otherwise make it clear that you _plan_ that Keep can do this at some point.
In general though it looks very interesting :).
