Google Optimize is gone. Grona is its next home.
Google retired Optimize on September 30, 2023. Grona picks up the job it left and adds the part Optimize never had: it researches your traffic, redesigns the page in chat, and ships the change as an A/B test on your live site.
The comparison
Google Optimize vs Grona
Grona is the Google Optimize alternative for people who liked testing changes on their live site and lost the tool when Optimize shut down in 2023. Grona does what Optimize couldn't: it researches your traffic, redesigns the page in chat, and ships that redesign as an A/B test, with a pointer to a full experimentation platform if you need more.

Where the change lives
The advantage
What Grona does that Google Optimize doesn't
Optimize could test the change you built. It never built the change, and it never read why your page was losing.
Research on your own data
Connect GA4 from the chat and Grona reads your real traffic, then layers in live competitor intel, so the redesign starts from what's actually losing conversions. Optimize only tested what you gave it.
Generates the redesign, images included
Ask for a stronger hero or a new section and Grona builds it into your existing page, AI images and all, ready to review. No variant to hand-edit the way Optimize made you.
Tests it, then ships it
Ship every redesign as an A/B test or a 100% rollout, target by traffic source, and see which variant wins on engagement. The free A/B testing Optimize took away, plus the change made for you.
Redesigns in place
Your pages, your domain, your traffic. Grona works on the live site through one snippet, or the native app on Shopify. Nothing to migrate, nothing to rebuild.
The honest part
What Google Optimize does that Grona doesn't
Optimize is gone, so there is no live tool to send you back to. But it is honest to say what Grona is not, and where a former Optimize user with different needs should look.
- If what you miss is a rigorous experimentation program with a significance engine and confidence scoring, that discipline is real, and Grona's A/B stays qualitative.
- If you need the depth Optimize never had, server-side testing, feature flags, and per-metric reporting, a dedicated experimentation platform like VWO or Optimizely is the closer replacement.
- If you only ever used Optimize for free A/B tests on copy and layout, and you'd also like the change designed for you, that gap is exactly what Grona fills.
The fit
Who should choose Grona
Built on 1,200+ experiments across 12+ industries. Product-page redesigns have seen up to 40% lift.
Read the MouthShield case studyGrona is ideal if you
- Used Google Optimize for free A/B tests and lost it in the sunset
- Want the change designed for you, not just a place to test it
- Run a live site and want research, redesign, and testing in one chat
- Are on Shopify, WordPress, Webflow, or any snippet-friendly CMS
- Want to see which variant wins without a paid experimentation contract
Grona may not be right if you
- Need a full experimentation platform with a significance engine
- Need server-side testing or feature flags
- Have a dedicated experimentation team running hundreds of tests
FAQ
Google Optimize vs Grona, answered
What replaced Google Optimize after it shut down?
Google Optimize and Optimize 360 were discontinued on September 30, 2023, with no direct Google replacement. Grona is where former Optimize users go to keep testing changes on their live site: it researches your GA4, redesigns the page in chat, and ships the change as an A/B test. For a full experimentation platform, VWO or Optimizely fills that role.
Does Grona work on the website I already have, like Optimize did?
Yes. One snippet on any CMS, or the native app on Shopify, and Grona works on your existing pages in place, the same way Optimize ran on your live site; your domain, SEO, and analytics history stay put, and each change ships as an A/B test or a 100% rollout.
Is Grona free like Google Optimize was?
Grona is free to build: you research, redesign, and preview at no cost, and pay only when a change goes live on your site. Optimize was free but only tested changes you built yourself; Grona builds the redesign for you, then tests it.
