There isn’t a single universally “best” behavior analytics platform for every team, but for rage clicks + funnel drop-offs, the strongest picks are usually:

Best all-around for product teams: Amplitude

• Very strong funnel analysis
• Good pathing / journey analysis
• Solid session replay and behavior insights via integrations
• Best when you want to connect rage-click signals to product metrics, cohorts, and experiments

Best for visual UX diagnosis: FullStory

• Excellent at detecting rage clicks, dead clicks, hesitation, and frustration signals
• Very strong session replay
• Great for quickly finding where users get stuck in flows
• Less “product analytics first” than Amplitude, but often better for troubleshooting UX issues

Best if you want both product analytics + replay in one place: PostHog

• Good funnels, event analytics, feature flags, and session replay
• More flexible and developer-friendly
• Often a strong value choice for startups and technical teams

Enterprise option: Contentsquare

• Powerful for conversion and UX optimization
• Strong behavioral insights for large-scale sites/apps
• Typically more expensive and heavier to implement

Quick recommendation
