Donnu A/B vs Google Optimize
Google Optimize was shut down in September 2023 and no longer runs. If you used Optimize and were left without a tool, Donnu is the natural replacement: no-code A/B testing, results in plain language and affordable pricing.
Google Optimize
Optimize was free and integrated with Google Analytics, which made it many peoples entry point into A/B testing. The problem is simple: it no longer exists, so the real comparison is about where to move.
Donnu A/B
Donnu takes what Optimize did well, the visual editor and the low barrier to entry, and fixes what was missing: honest statistics in clear language, real support and a light snippet that never breaks the page.

Frequently asked questions
- Why did Google Optimize shut down?
- Google discontinued Optimize and Optimize 360 on September 30, 2023, and suggested users move to A/B testing partners. The tool has not run since.
- Does Donnu integrate with Google Analytics like Optimize?
- Donnu has its own report with a Bayesian verdict and segments, and you can install it via Google Tag Manager alongside your GA. You are not locked into the Google ecosystem to read the result.
- Is moving from Optimize to Donnu hard?
- No. Since Optimize is already off, there is nothing active to export. You install Donnu, recreate whatever tests you want in the visual editor and go. It takes minutes per experiment.
