There is also the llm tool written by simonwillison: https://github.com/simonw/llm

I personally use "claude -p" for this

Compared to the llm tool, qqqa is as lightweight as it gets. In the Ruby world it would be Sinatra, not Rails.

I have no interest in adding too many complex features. It is supposed to be fast and get out of your way.

Different philosophies.
