What is the architecture/tech-stack used in building this? I didn't find this info neither on github readme, nor on website.

I like the fact that it is written in Go and small enough to skim over the weekend, but after repeatedly burning my time on dozens of llm ecosystem tools, I'm careful in choosing to even explore the code myself without seeing these basic disclosures upfront. I'm sure you'd see more people adopting your tool if you can provide a high-level overview of the project's architecture (ideally in a visual manner)
