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.
11 Companies That Use Haskell in Production

GitHub used Haskell for implementing Semantic, a command-line tool for parsing, analyzing, and comparing source code.
What happened with GitHub's semantic project?

As far as engineering effort, you can read this GitHub comment for an overview of where we’d like to take the project in the future. The tl;dr here is that the open sum type view of the world made it very concise to fold over syntax trees (since such a view of data is ultimately unityped, recursion schemes Just Work), but the tradeoff thus associated—namely, that you have to parse a concrete syntax tree into an open-sum view (a complicated and painful-to-read process), that you can never really be sure how a given syntax tree is shaped, and that the types don’t help you nearly as much as they could—proved to be too onerous to deal with. Going forward, we’re generating syntax types from the AST once per target language, and working on an abstraction (probably via this generated code; I made five separate efforts at using Generics for this, and failed every time) that recovers at least some of the convenience of recursion schemes. It turns out that recursion schemes over a mutually recursive syntax tree—as pretty much every language’s syntax trees are, in practice—are pretty much an unsolved problem, especially when extended to languages like TypeScript, which have hundreds of different syntax nodes.3 projects | reddit.com/r/haskell | 29 Jan 2022
I'm just curious. It seems there hasn't been much activity in https://github.com/github/semantic Is GitHub still using semantic it to power some code navigation features? Has it been abandoned or is there some successor project that has taken its place? Is there any writeup / lessons learned about this project?

is this from Github semantic (https://github.com/github/semantic)?
Seems very suspicious since it’s the same goal using the same technologies. The latest commit is 4mo ago but i assume they have a closed-source version they’ve been working on.6 projects | news.ycombinator.com | 9 Dec 2021
Cardano relying on Haskell is not bad at all

The semantic team at GitHub uses it for statically analyzing the dozens of languages that end up in GitHub repositories: https://github.com/github/semantic/blob/eaf13783838861fe5eb6cd46d59354774a8eb88d/docs/why-haskell.md
7 Useful Tools Written in Haskell
1 project | reddit.com/r/functionalprogramming | 3 Nov 2021
Yesterday I was looking for some examples of projects using tree-sitter (which is C) when I found GitHub's semantic, used to analyze and compare source code, and written in Haskell: https://github.com/github/semantic/
I just published an experimental `tree-sitter` grammar for Swift!
2 projects | reddit.com/r/swift | 28 Aug 2021
Does anyone here have experience with tree-sitter? If you aren't familiar, tree-sitter is a parser generator tool that builds parsers to use with an incremental parsing library. It's what's responsible for AST parsing on GitHub, for instance.
Glean -System for collecting, deriving and querying facts about source code
4 projects | reddit.com/r/haskell | 27 Aug 2021
You might want to put some examples of how exactly to use gleam (maybe a 1-2-3 type fashion?) on the front page if possible. This project seems like github/semantic or possibly even more advanced (given that it comes with it's own query language and a shell) but I just can't figure out exactly how I'd use it exactly.
A “Generalized” AST?

Rethink-app: DNS over HTTPS, firewall, and connection tracker for Android
8 projects | news.ycombinator.com | 29 May 2022
I'd imagine the app should work over IPv6-only networks thanks to 464xlat. I may be wrong, because I've never tested it on a IPv6-only network.
The reason for IPv6 is two fold:
1. Firewall today simply stores classless IP address rules as strings in a sqlite table fronted by a lfu cache backed by a typical hash-map. With IPv6, I'd imagine, this won't scale. So, we need a more economical in-memory data-structure (like a crit-bit trie  or art tree).
2. Apparently LwIP has problems with HappyEyeballs (I personally never saw it, but got a couple of reports from users about it that it was an unrecoverable error once the connectivity was lost, and the firewall had to be restarted). We're in the process of replacing LwIP with gvisor/netstack now , just to get IPv6 support back on track.
