COMPARISON
AB Tasty and VWO just merged.
And they're playing catch-up...
This industry consolidation validates our long-held belief that the future belongs to unified platforms, not fragmented point solutions. While they integrate, we'll continue to innovate.
Discover why leading enterprises choose Optimizely over AB Tasty and VWO.
Don't pause your roadmap just because theirs has
Two overlapping experimentation platforms, a shared vision for what comes next, and a lot of decisions in between. Which products survive? When will migrations happen? How will pricing change?
Your experimentation program can't wait for those answers. Optimizely is already what they're trying to build. Ready now.
Built on Optimizely Experience Optimization Platform
We are large enough to serve, small enough to care
We built the standard they're chasing.
Results you can stand behind
VWO's Bayesian model calls winners too early. AB Tasty's stats are lighter. When traffic is down and every test matters, you need confidence, not speed.
Optimizely Stats Engine is built by data scientists and statisticians to deliver accurate results. For advanced experimentation programs, we offer flexible methods, including CUPED, sequential testing, Bayesian, and Frequentist approaches, so you can customize for each use case.
The work you don't have time for
AB Tasty's Evi and VWO's Copilots are separate systems. After the merger, someone decides which one survives, and your AI-driven testing setup disappears with it.
Optimizely Opal understands your existing experiments, metrics, feature flags, and program history. The ideas, plans, and insights it generates are based on your instructions and program, not generic best practices.
Built for performance-sensitive environments
AB Tasty runs in the browser. Latency, flicker, performance drag. VWO's edge offering? A copy of what we were already doing.
Optimizely Edge Experimentation: Under 50ms. No flicker. No tradeoffs. From seamless SSR integration to self-hosted snippets, you get an implementation suite with unmatched speed and total architectural control that your platform demands.
Hear what the industry experts have to say
Optimizely has been lauded by top analyst firms, with a total of eleven leadership positions in DXP and personalization.

|
Analytics |
Prove impact as experiment data is tied directly to business outcomes. |
Simple dashboards that don't connect to the business metrics that matter. |
|
Roadmap stability | Plan with confidence. Consistent, clear product innovation that’s building features you ask us for. | With similar product offerings, AB Tasty and VWO will stop innovating to instead focus on consolidation work. |
|
Support |
Get help when you need it. Experimentation Services. Value and Adoption. CS teams invested in your success, not just your renewal. | Support teams stretched thin while two organizations figure out how to work together. |
When your platform is settled, you can focus on what matters to your business.
You can:
- Scale experimentation programs across teams without a platform transition getting in the way.
- Maintain predictable delivery and ship changes without disrupting stable workflows.
- Support performance-sensitive testing and execute experiments without sacrificing site speed.
Not only do analysts love us, but our customers do too.
But don’t just take our word for it — check out what they’ve got to say.
Analytics are vastly superior, platform UI is by far the easiest to use, and capabilities are best in class.
