I was recently much frustrated with speed of k9s that I use regularly and decided to create a rust alternative that is much faster. Architecture comes from me, and (shocking) Fable coded most of the things. My whole company switched to it and experience has been great - much faster, integrated tightly with Flux/helm/externalsecrets and develops much faster. I know that there is an overall sentiment on HN with using LLMs, so YMMV.
In terms of speed, you can check the benchmarks:

If you have issues - please open on Github and PRs are of course welcome!
