Speed is the easy number. Quality is the one that matters.
Every AI coding tool markets acceleration: more pull requests, more lines, faster merges. But raw speed is a trap if the code comes back as rework, reverts and midnight hotfixes. AI coding metrics exist to measure the trade-off, putting quality, rework and speed side by side so a fast quarter is not quietly a fragile one.
FeatureFactory scores AI-authored changes on the signals that predict durability: test coverage deltas, review depth, change size, and how much of that code survives untouched a week later. When AI output churns, you see it. When it holds, you can prove the acceleration was real. Dig into the mechanics in our AI vs. human code quality guide.
The goal is not to distrust AI. It is to make its impact measurable and defensible so engineering leaders can invest with evidence instead of vibes. See how it fits your workflow on the measure product page.
