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.

Viper – Go Configuration with Fangs
https://github.com/spf13/viper/blob/master/go.mod
16 direct dependencies, 39 transitive dependencies, and nearly 7000 lines of code -- for a package that handles flags and config files. I can't help feeling that frameworks like this are a little overwrought. It's the sort of project that succeeds because thousands of people just need something that works, right away, search for "golang config," and click the top result. If you can afford to slow down a little, you may find that you can config your app just fine with a few stdlib imports and a bit of glue.
Use viper with care. It has some dangerous fundamental flaws [1]. We got bitten hard, submitted a PR [2] and followed up for a year and a half to no avail, before I went ahead and reinvented the wheel and wrote koanf (plug), specifically to avoid viper's flaws.
Most importantly:
- Breaks JSON, YAML, TOML etc. language specs by forcibly lowercasing all keys internally. Dangerous because it can silently merge differently cased config keys into lowercase.
- Hard codes big unnecessary dependencies into the core, significantly bloating build sizes. No separation or abstraction.

14 great tips to make amazing CLI applications
configuration files. A few command line option libraries provide the option to use a configuration file alongside the command line parser (for example viper in golang). Otherwise, nothing is easier to use a JSON, YAML, or TOML parser to read in defaults and overrides.
