They state Luna is good enough, but its accuracy of findings is 74% whereas Astra is 96%. Dealing with false positives is expensive.

I am finding AI doing its own reviews as part of the process to be the key to productivity. I do subagent (fresh context reviews) at multiple stages with well-specified review criteria. It is really expensive to do with OpenAI or Claude API billing. Deepseek or the discounted monthly plans from OpenAI or Claude can be discounted similar to the 28x they state for Luna compared to Astra and you maintain much higher quality.

My thoughts exactly. That 22pp gap is massive, and it seems to me Astra is worth every extra penny.
