Simple, fast, and effective. Run experiments on your website without writing code, and declare winners in days — not months. Make decisions based on numbers, not intuition.
Testing shouldn't require a data team. Testio is designed so marketers, founders and product managers can launch experiments the same day they sign up.
Visual WYSIWYG editor. Click any element on your site and change text, styles, or visibility without touching a line of code. Copy-paste a single snippet and you're live.
Launch your first test in under 15 minutes. Our anti-flicker technology keeps page load under 100ms, so visitors never see a "flash" between control and variant.
In days, not months, you'll have a declared winner backed by statistical significance. Decide with real numbers, iterate, and keep optimizing your entire website.
An honest side-by-side comparison. No asterisks, no fine print.

Everything you need to know before trying Testio.
No. Google Optimize was shut down in September 2023 and all historical test data was deleted. Testio is built from scratch, so you'll recreate your experiments here — the upside is that our visual editor makes it faster than setting them up in Optimize originally. Most users create their first test in under 15 minutes.
It depends on your traffic and conversion rate, but for most websites with reasonable traffic you'll have a statistically significant winner in days, not weeks. Our dashboard warns you when a test doesn't have enough data yet, so you never ship false positives.
No. Copy-paste a single script tag (about 5kb) into your site's <head>
section. If you use WordPress, Shopify, Webflow, or any modern CMS, it takes under 5 minutes.
Once installed, everything — test creation, variant editing, goal tracking — happens in our
visual editor.
All experiment data is stored in our EU-based infrastructure. You fully own your data — we don't share or sell it, and you can export or delete it at any time. Unlike Google Optimize, you aren't required to tie your account to Google Analytics.
When you sign up you pick a plan and enter your payment details, but you are not charged during the 3-day trial. After day 3, the selected plan (starting at $9/mo) begins billing automatically. You can cancel in one click from the billing panel at any point before the trial ends — no forms, no emails to support, no retention calls.
Yes. Testio works with any website that lets you add a script tag — including Shopify, WordPress, Webflow, Wix, Squarespace, custom HTML, React, Next.js, Vue, and any static site.
