spekt8 VS Sourcetrail

In my experience it tends not to be done because there's an inevitable drift between the system as it actually operates and the relevant visualizations and diagrams. I have seen them used as a starting off point at times, although that's also been infrequent.

There is however a growing movement of being able to visualize how a system is functioning at various levels. XState/Statecharts are a good example (https://xstate.js.org/viz/). Another example in the Ops space would be https://github.com/spekt8/spekt8 for K8S. I work at Grafana and we're more or less trying to expose these things in ways that make sense. Our bread and butter is timeseries data but we're adding more in that regard (it's possible to build node graphs from running systems).

I wish something existed in this space. I used Coati Software's Sourcetrail for a couple of years. Unfortunately it was discontinued. It was a wonderful piece of software that indexed a code repository, and exposed an interface to explore it interactively. At least for me, it significantly improved the understanding and legibility of code.

The code is in an archived state (https://github.com/CoatiSoftware/Sourcetrail). Searching for the software on Google shows some screenshots.

I think it might make large scale code visualization in a similar way to how SourceTrail does it more feasible: https://github.com/CoatiSoftware/Sourcetrail

I've used https://github.com/CoatiSoftware/Sourcetrail in the past for some bits of the legacy code project I'm on. I also use vim and cscope for day to day navigation but it's harder to get a big picture with those alone.

Sourcetrail?

Does it strive to do what Sourcetrail used to ?

You could always try using Sourcetrail. Unfortunately the open source project is now archived but it should still help you get insights into your code.
