Free Plan Comparison

Limits change—always check current pricing pages.

How to Get the Most From a Free Plan

1. Exclude internal traffic. Your own team's visits burn your quota. (DeepSync's WordPress plugin skips wp-admin automatically.)
2. Don't record staging. Use a separate project or exclude the domain.
3. Focus on key flows. Signup, pricing, checkout. Watch 10–20 sessions per question.
4. Use filters, not random browsing. Rage clicks, errors, and exit pages lead to issues faster.
5. Wire up consent properly. In consent-required mode, nothing records until your banner sends consent. See consent modes.

When to Upgrade

Upgrade when the free plan stops answering questions, not when it fills up:

• You need more funnels and goals to analyze multiple flows.
• You need device-segmented heatmaps to separate desktop and mobile behavior.
• You want AI summaries, live view, or attribution.
• You need 90+ days of history to compare before/after a release.

Key Takeaways

• "Free" plans differ in sessions, sampling, retention, and features.
• DeepSync's free plan includes replay, heatmaps, and JS errors with no sampling.
• Protect your quota by excluding internal and staging traffic.
• Upgrade when you need answers the free plan can't give.

Conclusion

The best free session replay tool is the one that helps you fix something this week. Install one, watch 20 sessions of your most important flow, and you'll know more than any dashboard could tell you.
