Flowsery is a session replay and analytics platform that uses AI to detect issues in user sessions, rank them by impact, and provide steps to reproduce along with replay videos. It integrates with tools like Linear, Jira, Slack, and payment providers to alert teams, automate fixes via pull requests, and attribute revenue to traffic sources in real time.

Flusterduck is an automatic issue tracking software focused on detecting user confusion and UX friction on websites. It identifies repeated user frustration, estimates its revenue impact, and verifies fixes after deployment without using session replays or capturing form values.
THE PRODUCT, BEYOND THE PITCH
Automatically researched · Not editorially reviewed · Sources checked Nov 1, 2026
A good fit for
- Development teams and product managers who want to identify and fix UX friction without watching session replays.
Know the limitations
- Does not record session replays or capture user-typed form values or keystrokes to protect privacy.
- Requires adding a single script tag or package to the website to collect behavioral signals.
What you can do
- Detecting and prioritizing UX friction issues that cause user confusion and lost revenue on websites.
- Verifying that deployed fixes actually reduce user confusion and friction.
Features
- Detects 120 behavioral signals including rage clicks, dead clicks, form friction, navigation loops, and more.
- Clusters repeated user friction into ranked issues with cited evidence and affected elements.
- Verifies fixes after deployment by comparing confusion before and after and confirming if the fix worked.
- AI-assisted diagnosis drafts root cause and fixes for issues based on real visitor sessions.
- AI Guide explains confusing elements to users in real time to reduce bounce rates.
Integrations
- GitHub integration to open draft pull requests for Autofix suggestions.
- Slack alerts and two-way Linear sync available on Scale and Pro plans.
- Email alerts, PagerDuty alerts, and webhooks for alert routing.
Platforms & data export
