Custo automatically detects user‑experience problems such as rage clicks, dead clicks, drop‑offs, and errors by analyzing session replays from PostHog, then ranks them by impact. It offers three immediate remediation paths: pre‑built UI elements like tooltips, banners, and toasts; AI‑generated code‑fix prompts that can be pasted into tools like Cursor or Claude; and Slack alerts for critical issues. This lets product teams quickly resolve silent issues without manual debugging.

Problem
Web applications often suffer from unnoticed user friction such as rage clicks, dead clicks, unexpected drop‑offs, and runtime errors. These silent issues reduce conversion rates and increase support costs, yet they remain hidden without manual session analysis.
Solution
Custo integrates directly with PostHog session replays to automatically flag every rage click, dead click, drop‑off, and error, ranking them by the number of affected users. Detected issues are delivered as Slack alerts and displayed in a unified issue dashboard. For each problem, Custo offers three remediation paths: UI nudges (tooltips, toasts, banners, tours), AI‑generated code‑fix prompts that can be pasted into editors like Cursor or Claude Code, and automatic creation of pre‑filled Linear tickets for backlog tracking. This workflow lets product, design, and engineering teams resolve user problems instantly or schedule them efficiently, improving experience without the overhead of manual triage.
Target Audience
