Crazy Egg vs Optimizely

Choose Crazy Egg if you need to send variant assignments to Google Analytics. Choose Optimizely if you run experiments across pages, apps, or warehouse data. Start for free with Crazy Egg, then move to a monthly paid plan.

Marketers studying a page can use Crazy Egg's heatmaps to see clicks and scrolling, then send variant assignments to Google Analytics. Session recordings tag rage and dead clicks, while visitors can answer questions through Crazy Egg's branching popup surveys. These tools suit teams who want a visual account of page activity without building a GA4 report. Some users report that its A/B tests flicker between variations, making results harder to interpret.

Teams running experiments across a checkout can use Optimizely's multi-page tests to keep one experiment consistent across the sequence. Sequential testing supports early stopping without raising false positives. Feature flags support staged rollouts, with SDKs for experiments in server applications and mobile apps. Guardrail alerts watch secondary metrics during a test. Optimizely computes experiment results on the team's own warehouse rather than a vendor copy.

Crazy Egg users praise easy setup and clear heatmaps, while some report poorly signposted annual billing, unhelpful support, and glitches in A/B tests. Users also mention page-view caps and pricing that feels high against alternatives. Optimizely users describe quick help with simple issues by phone or email, while others report slow support after signing, long email waits, and staff turnover.

Crazy Egg says heatmaps and A/B tests helped an ecommerce business rework its homepage. A search bar variant went further than the team's earlier test. Optimizely's customer story follows an oral care seller whose nontechnical teams ran their own experiments. A refill quantity test raised conversion, purchase units per transaction, and subscription units per transaction.
