TREX
Greptile agent that runs a pull request's branch in a sandbox and writes and executes tests against it, to catch the bugs that only appear at runtime.
No separate price: a TREX review consumes 3 review credits where a standard review consumes 1. The free Starter plan carries that same credit line — 'Unlimited repositories', '50 credits per month: 1 credit = 1 standard review, 3 credits = 1 trex review', '1 active developer' — so the free allowance covers THIS product, not merely the parent. Pro $30/seat/month repeats the line per seat, $1 per additional credit; Enterprise is custom.

AI code review that indexes the whole repository before commenting on a pull request, so its comments carry the context of code the diff does not touch.
