Google Optimize alternative
Miss Google Optimize?
Here's its upgrade.
Google discontinued Optimize in September 2023 and left a generation of teams without a free, simple A/B testing tool. ProveLift fills that gap the way Optimize users expect — a visual editor, split-URL tests, a free plan, tight GA4 integration — and goes further with trustworthy statistics and server-side price testing for e-commerce.
Free plan available • No credit card required • Setup in minutes
Everything you used Optimize for
Visual editor
Point-and-click changes to headlines, buttons, images and layout — no code, no deploy.
A/B and split-URL tests
Classic A/B/n experiments plus redirect tests between entirely different pages.
Free plan
Like Optimize, you can genuinely start for free — paid tiers only scale traffic, domains and seats.
GA4 integration
ProveLift pushes each exposure into your GA4 as an event with the experiment and variant, so you can segment any GA4 report by variant — and it can pull GA4 conversions back into your results.
Audience targeting
Target by URL, device, geography, UTM parameters, referrer, cookies or custom JavaScript.
Flicker-free rendering
A synchronous anti-flicker loader applies variants before first paint — visitors never see the original flash by.
…and what Optimize never had
- ✓Server-side price testing — A/B test the real price of a product on WooCommerce, PrestaShop or Magento. The price shown is the price charged, and the winner is decided on revenue per visitor.
- ✓Decision guardrails — winners are held until minimum runtime and sample thresholds are met, so you don't ship a false positive from peeking early.
- ✓SRM detection — broken traffic splits are flagged automatically instead of silently corrupting your results.
- ✓Revenue tracking — orders arrive with value and currency, so experiments are measured in money, not just conversions.
- ✓AI test ideas — an AI audit of any page suggests the highest-impact experiments to run next.
Switching takes an afternoon
-
1
Create a free account
Sign up, add your domain, and install the snippet — or the WordPress/WooCommerce plugin if you're on WordPress.
-
2
Recreate your tests
Rebuild each experiment in the visual editor (most take a few minutes) or as split-URL tests, and set your goals.
-
3
Connect GA4 (optional)
One OAuth click connects your GA4 property so variant exposures land in your reports as events.
-
4
Launch
Start the experiment and watch results in real time — the statistics engine will tell you when a winner is safe to call.
Frequently asked questions
Why was Google Optimize discontinued?
Google sunset Optimize and Optimize 360 in September 2023 to focus on GA4 integrations with third-party testing tools. Existing experiments stopped running, and there was no direct replacement from Google.
Is ProveLift free like Optimize was?
There is a real free plan — enough to run your first experiments on a smaller site. Paid plans add traffic volume, domains and team seats, and remain priced for small businesses, not enterprises.
Does it work with GA4 like Optimize did?
Yes, two ways: ProveLift pushes each exposure into your GA4 property as an event carrying the experiment and variant (so you can build any variant-segmented report), and it can import GA4 conversion events back into your experiment results.
Do I need a developer to use it?
No. Installing is pasting one snippet (or activating the WordPress plugin), and experiments are built in a point-and-click visual editor. Developers get an API, webhooks and server-side testing when they want them.
