Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
We haven't tracked posts mentioning failure yet.
Tracking mentions began in Dec 2020.

capability - Extensional capabilities and deriving combinators
motor - Type-safe effectful state machines in Haskell
exceptions - mtl friendly exceptions
eveff - Efficient Haskell effect handlers based on evidence translation.
