Make your agents faster, cheaper and better.
Costzera reads your production traces against your code, then finds and fixes the behaviour that wastes time and money.
more efficient on open source agents: cheaper, faster, and better answers.
Agents waste time and money in ways that are hard to see and harder to fix.
An inefficient run still returns the right answer, so nothing alerts. The bill and the latency grow one trajectory at a time.
Finding the cause means combing through thousands of traces, guessing which retry loops or which model is overkill, and matching spans back to the code that produced them.
Shipping the fix is no easier: hand-tuning configs, building replays to check quality held, and re-checking every time the agent changes.
The answer isn’t another cost dashboard.
It’s agents that read your production traces against your code, and automate the path from detection to fix to maintenance.
From trace to shipped fix, in one place.

Questions
You can’t find these inefficiencies by reading code alone. It takes production traffic to reveal the signals and patterns — which retry actually loops, which model is overkill for the work it’s doing, which context is dead weight on every call. Signal in the traces. Fix in the code.
