Where the change lives
The advantage
What Grona does that Optimizely doesn't
An experimentation platform tells you which idea won. It never has the idea, and it never builds it.
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, not a blank hypothesis.
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 variation to spec and hand off to engineering.
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 test and the change live in one place.
Redesigns in place
Your pages, your domain, your traffic. Grona works on the live site through one snippet, or the native app on Shopify. No engineering sprint to stand it up.
The honest part
What Optimizely does that Grona doesn't
Optimizely is a genuinely strong platform, one of the deepest in the category. If your work looks like one of these, Optimizely is the better fit, and this section means it.
- If you run a large experimentation program and need a full significance engine, stats reporting, and program governance, Optimizely is built for that. Grona keeps A/B qualitative.
- If you need feature flags, server-side experiments, and progressive rollouts wired into engineering, Optimizely is built for that team.
- If you have a dedicated experimentation function running hundreds of tests a quarter, Optimizely's depth pays off in a way a redesign tool does not.
The fit
Who should choose Grona
Built on 1,200+ experiments across 12+ industries. Product-page redesigns have seen up to 40% lift.

- Want the change designed and built for you, not just a rigorous place to run it
- Run a live site and want research, redesign, and testing in one chat
- Don't have an engineering team to spec and build variations
- Are on Shopify, WordPress, Webflow, or any snippet-friendly CMS
- Want to see which variant wins without a six-figure annual contract
Grona may not be right if you
- Run a large experimentation program that needs a significance engine
- Need feature flags or server-side experiments
- Have a dedicated experimentation team and program governance needs
FAQ
Optimizely vs Grona, answered
What is the best Optimizely alternative for redesigning a live site?
Grona is the Optimizely alternative built for teams that want the change designed for them: it researches your GA4, redesigns the page in chat, and ships the redesign as an A/B test on your live site. Optimizely stays the better fit when you're running a large experimentation program that needs a full significance engine and program governance.
Does Grona work on the website I already have?
Yes, that is the whole product. One snippet on any CMS, or the native app on Shopify, and Grona redesigns your existing pages in place; your domain, SEO, and analytics history stay put, and each change ships as an A/B test or a 100% rollout.
How does Grona's pricing compare to Optimizely's?
Grona is free to build: you pay only when a redesign goes live on your site. Optimizely publishes no per-SKU price and sells annual contracts, with standalone Web Experimentation starting around $25K a year and scaling into six figures by traffic. Grona is priced for shipping redesigns, not for enterprise seat-and-traffic contracts.
