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.

Could I get a code review?
This one is highly specialized, but I'm a huge fan of Suture for managing long lived goroutines.

[gopulse/pulse] the Golang framework designed to ensure your web services stay alive.
In English, your phrasing doesn't come off as a play on words/a reference to the name, so much as it describes a feature of the library. The expectation is, with the description you've given it, the library would handle some form of resilience in service management. I half expected the library to be similar to Suture.

Ergo: Erlang/OTP Implemented in Golang
It does not give you a way to reliably track arbitrary goroutines that "this" goroutine (for whatever that may be) wants to track, the way an Erlang process can just "link" to anything it is capable of naming the PID for.
However, you can construct a reliable mechanism where one goroutine can start another and know whether or not the one it started has failed by using the available primitives, as I did in https://github.com/thejerf/suture . It's an easier problem since there's no cluster and no network that can get in the way. I've also done the exercise for the network case: https://pkg.go.dev/github.com/thejerf/reign#Address.OnCloseN... but that only functions within the network defined by that library because, again, it just isn't arbitrarily possible.
(I suppose it's relevant to some of my other comments to point out that I've also implemented basically Erlang-style concurrency in Go, with network, but as a relatively idiomatic translation rather than a blind one.)

Is there an equivalent to Elixir / GenServer in Go? Trying to create the same request / response pattern with better performance but not sure where to start.
If you also want Supervisor-like behavior, take a look at suture.

Start an already running service: no error, error, or panic?
For context, I've been working with similar interfaces for many years through suture.

Erlang vs Golang
I wrote suture for idiomatically-ported supervisor trees (that is, the ways they differ are deliberately chosen, not accidents), and reign for Go-native cluster-like support. I use suture in almost everything I write. Reign is used on production services but I don't generally use it because I think modern stacks have better options with modern message busses, but it can be useful for porting.

How “let it fail” leads to simpler code
I think the distinction between expected and unexpected errors can easily fall through the cracks and writing code in a way that an unexpected error doesn’t break everything is quite powerful.
Golang makes it easy to ignore errors that can be ignored and defer/recover provide a way to implement a way to “let it fail”
There’s even an implementation of supervisor trees for Go [0] :)

Golang vs Elixir protoactor supervision
(If you'd like something lighter weight, suture is a supervisor library without a whole lot of other stuff. If you want that other stuff, by all means, go to town.)
-
The method to manage multiple services in a process.
This is the primary reason almost every program I write ends up using suture. The restarting is nice when it works, but Go code is often reasonably robust. (Not 100%, but reasonably.) But it's a nice organization principle.

Could I get a code review?
They're supported, but as you said, you have to map them yourself. There's a nifty library that does this for you if you want to save some time.
