Optimizely is powerful — and priced for enterprises. Testio gives you the 90% of A/B testing that startups and SMBs actually use, at $9/month instead of $2,000+/month. No sales calls. No contracts. Start testing today.
Optimizely is a great tool. It's just the wrong tool for most teams under 100 people. Here's what our customers tell us.
Optimizely's Web Experimentation starts around $2,000/mo in quoted contracts. Testio starts at $9/mo on a public pricing page. Same core capability, built for smaller teams.
No sales calls, no onboarding call with a CSM, no "implementation partner." Paste a 5KB snippet in your <head>, launch your first test from the visual editor.
Visual editor, device/geo targeting, multi-goal tracking, Z-test + Bayesian significance, auto winner declaration. Everything most teams actually use — none of the feature bloat.

For client-side A/B testing — yes, directly. Both offer a visual editor, statistical significance testing, automatic winner declaration, and audience targeting. Testio does not offer Optimizely's server-side / Full Stack product or personalization engine; if you need those, Optimizely is the right choice.
Optimizely is priced for enterprise sales, not software cost. Testio is self-serve, which removes the sales team, CSM team, and implementation team from the price. We built the features that small marketing teams actually use, and skipped the enterprise-only features (Full Stack SDKs, multi-armed bandits, personalization). That focus lets us price at $9–$299/mo.
Yes. Subscriptions are month-to-month, cancelable self-serve from the billing panel. No contracts, no retention calls, no forms.
The Testio snippet is ~5KB, loads asynchronously, and has a 100ms anti-flicker timeout. Core Web Vitals (LCP, CLS, INP) are designed to be unaffected. This is often better than Optimizely's default implementation, which can be heavier depending on what you've enabled.
Full product access. You can create unlimited experiments, invite your team, install the snippet, and see real results during the trial. No credit card required to start; you add payment if you want to continue after day 3.
Yes. Any website where you can add a script tag — WordPress, Shopify, Webflow, Wix, Squarespace, custom HTML, React, Next.js, Vue, Nuxt, Astro, SvelteKit — works. The snippet is framework- and CMS-agnostic.
