Uxsniff

UXsniff is a web-based user analytics platform for website owners, UX teams, and product managers that detects UX changes automatically and explains how those changes affect user behavior.

Key capabilities include:

• Change Radar to flag user-visible changes (layout, copy, CTAs, interaction flows) and connect them to behavior shifts
• Retro A/B (Time-Travel A/B) to compare real user behavior before vs after a release, without planned experiments or traffic splits
• Session recordings + heatmaps to validate findings with evidence, plus historical comparisons (including Wayback Machine access)
• Rage Alerts to surface frustration signals such as rage clicks, dead clicks, repetitive scrolling, and other unusual interaction patterns

Pricing: Paid, starting at $9/month (a free start option is available).

What makes it notable is its focus on change → impact investigation for production releases. Instead of relying only on dashboards and manual replay review, it prioritizes the few UX changes most likely tied to KPI movement, and adds AI-driven summaries and audits (including a GPT Assistant via OpenAI’s Generative API).
