At a Glance

Heatmaps

Crazy Egg built its reputation on heatmaps and offers several visual report types, which marketers find approachable.

DeepSync provides click, scroll, and attention heatmaps on every plan. Two things distinguish them:

• Layout accuracy. Each heatmap is built from a single layout, bucketed by viewport width rather than hardware, so clicks land on the right element (why this matters).
• Filters recompute. Filtering by device, browser, country, or UTM source runs a new scan rather than recolouring one dataset, and compare mode shows two segments side by side.

Recordings and Debugging

Both record sessions. DeepSync adds the console and network timeline to the replay and links JavaScript errors, grouped and ranked by affected sessions, to the recordings where they occurred. That makes it usable by engineers as well as marketers.

Funnels in DeepSync open directly into the sessions that dropped at a step, which connects the number to the cause.

Testing

This is Crazy Egg's clear advantage. It includes A/B testing, so you can test a variation without a separate tool.

DeepSync does not run experiments. It helps you find what to test and confirm what a change did (test ideas from session replay). If you need built-in testing, pair DeepSync with a testing tool or choose Crazy Egg.

Pricing Approach

• DeepSync: a free plan with 1,000 sessions a month, self-serve Pro at ₹1,999 a month, every session recorded up to the limit with no sampling, and no overage charges.
• Crazy Egg: paid plans after a trial, structured around tracked pageviews and recordings. Check the current plan page.

Who Should Choose Which

Key Takeaways

• Crazy Egg combines heatmaps with built-in A/B testing.
• DeepSync covers heatmaps, recordings, funnels, errors, and performance.
• DeepSync's heatmaps are built per layout for accuracy.
• Pick by whether testing or diagnosis is your main job.

Conclusion

If your work is testing page variations, Crazy Egg fits. If your work is understanding why people drop out of flows and fixing it, DeepSync covers more of the investigation.
