Hi Product Hunt,
We built Cookiebench as a way to benchmark our own cookie banner, but it quickly turned into something bigger.
Most developers don’t have a clear way to see the real impact of cookie banners on their site’s performance, especially when it comes to things like bundled vs external IIFEs, hydration timing, and layout shift. Cookiebench gives you that visibility.
It’s a controlled benchmark. You can’t test your own site just yet, but you can compare popular CMPs side by side and see how they affect performance, how much script they inject, and whether they stay bundled or not.
If you’ve ever felt stuck choosing a CMP without really knowing what’s happening under the hood, this should help.

Finally, real transparency on how consent popups impact speed and user experience—this feels like a must-have for every web team.
