One page, one set of third-party tags, the consent platform as the only variable — measured on 2026-09-04. Identical page, cold cache, 1.6 Mbps / 150 ms RTT, 4× CPU throttle, median of 9 runs. Baseline LCP without any consent platform was 299 ms, and anything within ±15 ms of it reads as no change. Every platform rendered its banner on every run.

Moving over takes an afternoon.

Cookiebot gives you a hosted banner and a script tag. Katla gives you that too, and then everything behind it: headless mode when the banner should be yours, a React and Next.js SDK, a CLI for scripted onboarding, and an MCP server so an assistant can audit your cookies. If the consent layer is something your team builds against rather than merely installs, that difference is the whole decision.
