Where Corexi and Optimizely differ.
Optimizely is built for experimentation and feature delivery at scale. Corexi is the UX measurement and fix layer that runs alongside it. Here's how they differ.
What Optimizely is great at
Optimizely is a powerful platform for feature flagging, A/B testing and content management — engineering-grade experimentation for large teams.
Where Corexi takes a different path.
- Measures, doesn't just test
Optimizely runs the experiments you design. Corexi continuously measures UX quality and ties every gap to conversion impact — no experiment setup required.
- One score across the product
Instead of reviewing data point by point, get a UX Score with prioritized, evidence-backed findings across 9 categories.
- Fix-ready code + accessibility
Every finding ships code; WCAG is axe-core verified; neurodiversity is scored as a first-class dimension.
- Continuous, on every deploy
Corexi re-scans automatically as your product ships — the score is a living pulse, not a one-off snapshot.
Corexi and Optimizely, row by row.
| Corexi | Optimizely | |
|---|---|---|
| Role | Find + diagnose + fix | Experiment + flag |
| Starting point | Full-product scan | A hypothesis |
| Output | Scored findings + code | Experiment + rollout |
| Fix-ready code | Yes, IDE-native | — |
| Accessibility | axe-core verified | — |
It depends on the question you are asking.
You need enterprise experimentation and feature management across large product teams.
You want continuous UX measurement, prioritized findings and fix-ready code.
Better together. Use Corexi to find and fix friction continuously; use Optimizely to experiment on the changes that need proof.
