Slow load times and decisioning latency

AB Tasty Performance

Optimizely reduces client-side latency by moving experiment evaluation from the browser to the Edge. AB Tasty has no Edge-based experiment delivery and customers cite AB Tasty’s latency as a key concern.
Complaints in public reviews cite AB Tasty’s page load times, library widgets and the weight of AB Tasty’s tag as key concerns impacting performance and latency.

Limitations to running many tests at the same time

AB Tasty Scale

AB Tasty lacks a Stats Engine to support experimentation at scale and lacks an elegant way to avoid collisions when running multiple tests at the same time. Instead, AB Tasty offers a cumbersome and manual workaround using filters to identify conflicts.
Optimizely eliminates spill-over effects natively so digital teams can run multiple experiments on the same page or in a single app.

Cumbersome QA required

AB Tasty Single Page Apps & mobile testing

Publicly-available comments by AB Tasty customers reveal challenges on mobile and single page applications (built in REACT, Angular, Vue, etc.) citing time-consuming QA. Reviews flag the following issues:

Time-consuming QA due to the tag reloading and a capricious page editor with single-page application websites
Difficult QA process on mobile, as editorial changes aren't reflected accurately
Technical/expert profile is recommended for complex setups especially on Single Page Applications

When asked what alternatives were considered? “AB Tasty”… “Optimizely has better customer service if you need to talk to a person and a great library of documentation if you run into issues and want to troubleshoot yourself… Optimizely added many new possibilities that were not available on the other testing platform.”
