# Flusterduck: Stop losing money to confused users

Canonical: https://flusterduck.com/

Confused users are quietly costing you money. Flusterduck finds where real users get stuck, puts a dollar figure on every friction point, and ranks your fixes by revenue at risk, then confirms the fix worked after you ship. Setup takes about 4 minutes.

What you get: 100 signal detectors · no session replay · no PII, ever · one script tag · MCP built-in · fixes verified on deploy · revenue at risk, per issue · TypeScript-first · Slack, Linear, and GitHub integrations.

## The problem: UX friction is invisible

- Users don't file bugs. They just leave.
- Session replays take hours to watch. Nobody watches them.
- Analytics tells you WHAT happened. Never WHY.

Friction isn't meant to be hunted. It's meant to be seen.

## What Flusterduck does

1. Detect. 100 behavioral detectors watch clicks, scroll, and timing on every page. Rage clicks, dead clicks, form friction, navigation loops, captured as they happen.
2. Cluster. Repeated friction becomes one ranked issue, with the root cause, the affected element, and a recommended fix attached. No replay marathons.
3. Verify. After you deploy, we compare confusion before and after and tell you whether the fix worked. Closed means proven, not hoped.

The landing page shows a worked example (illustrative numbers on an example checkout): three issues worth $11,140/mo at risk in total, topped by "Users rage-click the disabled checkout button" on /checkout at $4,210/mo, with a recommended fix and a verified confusion-score drop from 87 to 12 after the deploy that fixed it.

## For developers

One tag, or one package. TypeScript-first. Async and non-blocking. No PII, no form values. An MCP server for your AI tools. Details on the developer page: https://flusterduck.com/developers (markdown twin: /developers.md).

## Supercharged by AI

Every issue is diagnosed by AI the moment it's found: root cause and fix, written for you. Two AI surfaces you can watch work:

- Guide (experimental): when someone hesitates on a baffling element, Guide explains it in plain language right there, so they finish instead of bouncing. Every question they ask is also first-party evidence of where your UX loses people.
- Autofix: from the same evidence, Autofix writes the code-level change, and with the GitHub App connected it researches your repo and opens a draft PR. You review and ship; it never merges on its own.

## Pricing

Three plans: Grow $99/mo, Scale $249/mo, Pro $499/mo, plus Enterprise at custom pricing. Session limits are pooled across your whole org, not per site. Every plan starts with a 3-day free trial (card required, not charged until day 3, cancel any time before then). Full details: https://flusterduck.com/pricing (markdown twin: /pricing.md).

## Why we built it

Every team we've been on knew users were struggling somewhere, and nobody could say where. The bugs never got filed. The replays never got watched. The friction just sat there, quietly costing money. You don't need session replay or ten dashboards. You need to see where users struggle, and a ranked list of what to fix first. The duck watches. You ship. We confirm it worked.
