Show HN: GetStack.dev – Track GitHub open-source trends
50 points - 05/23/2025
Hi HN!
I’ve been working on getstack.dev[1], a tool to help developers track GitHub open-source trends, tech adoption, and repository stacks — updated weekly.
About a month ago, I broke my leg. While stuck on the couch, I figured I’d put the downtime to good use and finally build a side project I’d been thinking about for a while. So I put together an MVP and decided to release it publicly to gather feedback.
I have always struggle to grasp how people are adopting technology and what's really hype or under the radar. As tech leader you also often want to know if your tech choices are the right one but it's hard to take a data driven solution. And as open-source lover I always want to know how my favorite projects are built.
All the data is pulled and refreshed weekly from GitHub, stored on ClickHouse [2] but you can directly check how I built it in the website [3]

I’m not sure how to take “open source” when there are closed source commercial things on the trends list.
It's true, but source available is less sexy and understandable
Some of the categories don't make sense to me. Angular is not a language, neither is Deno, for example.
I agree, sometimes it's hard to put a label that would fit what most people expect. In the case of Angular I have put it in languages because I put React there too, React is there because it has a specific file extension and language.
I could put them in framework but they would be mix with a lot of stuff that people do consider framework and not languages.
Same for Deno (and nodejs and bun) they would fit better in a Runtime category maybe but I'm not sure people would understand that category and that it would make a meaningful comparison.
I sympathize w OP; the ecosystem doesn't always fit into a clear ontology. That said, you're 100% right that those 2 examples were miscategorized.

Thanks there was an issue with the Api key
What is the value for me as a software engineer to watch this?
E.g. How does the metric work.
I searched for Kotlin repository but it was not found. It has like 50K stars.
The repo has been ignored from compilation because it's too big to parse in a reasonable time, all of this is quite costly. Tried to be smart by filtering the search but maybe it's confusing in that case

I feel like the way you present "trends" like on here: https://getstack.dev/category/language
...is less than useful, because (roughly) no one deletes old repos and code, so everything will always be trending "up."
I'd be more interested in a stat that perhaps considered "number of active repos that have this language, or, this language's share of representation among repos with activeness in the last month. With some reasonable definition of "active," of course.
It's more or less that, the about section answers this. It's parsing popular repo that has been active in the last 2 years. It's a long period but otherwise the trend would move too much that would make them useless and a lot of popular repo are not maintained or don't need regular update
The percents are... change per week?
