• Performance Monitoring: Sub-1% overhead on page load; scales to 1M+ sessions/month, but caps replay length at 30min without premium.
• Data Export/API: Full GraphQL/REST access to replay metadata; GDPR-compliant anonymization, but no self-hosting option.

Best For

Ideal for engineering teams embedded in Amplitude's analytics stack needing event-correlated replays for web apps; opt for LogRocket or Quantum Metric if prioritizing mobile-first or lower-cost standalone heatmaps over deep integrations.

Sentry

Overview

Sentry's Session Replay captures and replays user sessions to debug errors and performance bottlenecks in web and mobile apps, while its heatmaps visualize clicks, scrolls, and hovers for UX analysis. It targets developers and engineering teams building production software, integrating deeply with error monitoring for root-cause debugging. The key differentiator is its native tie-in to crash reporting and traces, outperforming standalone tools like Hotjar or FullStory in technical depth but lagging in advanced behavioral analytics compared to LogRocket or Microsoft Clarity.

What Technical Users Love

Developers praise Sentry's Session Replay for seamless integration with error tracking, enabling quick reproduction of bugs without manual logs, and its SDKs for easy setup across frameworks like React and Flutter.

• "Sentry Slow Query 분석을 포함해서 Session Replay 너무 좋다." – @ink_punctuation, on combining slow query insights with replays for mobile debugging source.
• "Resolved around ~15 bugs past 2 weeks, Sentry was perfect to guide me thru each step and understand what happens. Runtime bugs are a world different thing from Buildtime bugs." – @renatoaraujoc, highlighting replay's role in frontend error resolution source.
• "You may not like it, but this is peak bug fixing. Still not used to getting an email from Sentry about an error and realizing the fix is already in a PR." – @miguelbetegon, on AI-assisted debugging via replays source.
• "Sentry for bug tracking... for session replay and A/B testing stuff." – @artkulak, noting easy integration in startup stacks source.

What Frustrates Technical Users

Technical complaints center on performance hiccups in high-volume setups, incomplete heatmap features, and occasional API reliability issues, especially when compared to more UX-focused rivals like FullStory or Quantum Metric.

• Dashboard and API endpoints occasionally hang indefinitely during high-load queries, disrupting debugging workflows – @Fykowo on project loading failures source.
• Lacks native heatmaps for comprehensive UX tracking, forcing reliance on session replays alone, unlike Hotjar or Crazy Egg – Reddit user review on feature gaps source.
• Pricing scales poorly for small teams with growing event volumes, leading to unexpected costs and potential drop-off – @kz_developer on high costs source.

Key Capabilities

• Error-Linked Replays: Automatically records sessions around crashes or slowdowns, with console/network traces for precise debugging.
• Interaction Detection: Identifies rage clicks, dead clicks, and slow networks in replays, integrated with performance vitals.
• Cross-Platform SDKs: Supports JavaScript, React Native, iOS/Android with minimal overhead (under 1% CPU), plus API for custom event tagging.
• Basic Heatmaps: Aggregates click/scroll data per page, filterable by user segments, though less granular than dedicated tools.
• Privacy Controls: Masking for sensitive fields (e.g., PII in forms) and sampling to limit data volume, compliant with GDPR.

Best For

Sentry excels for engineering teams prioritizing error-correlated session replays in dev-heavy environments like those using Amplitude for analytics; opt for LogRocket, FullStory, or Hotjar if pure UX heatmaps and behavioral segmentation without monitoring ties are needed.
