As answered by people managing Optimizely and TraceUX.dev.
TraceUX.dev's answer:
ReplyPro uses TraceUX to monitor platform errors and get alerts on Slack
TraceUX.dev's answer:
Go powers the backend, SQLite handles storage, and React, TypeScript, and Vite power the dashboard. The TypeScript browser tracker uses rrweb to record DOM events, while rrweb-player reconstructs sessions for playback. The dashboard is embedded in the Go binary, and Docker deployment is also supported.
TraceUX.dev's answer:
At the company I worked for, we used Smartlook to understand user behavior and investigate problems. When Smartlook shut down, we looked for a replacement, but the alternatives we found were too expensive. That led me to build TraceUX as a side project in my time outside work.
TraceUX.dev's answer:
Independent developers, technical founders, and small product teams running web applications.
TraceUX.dev's answer:
Choose TraceUX if you want to understand user behavior while keeping recordings on infrastructure you control. It is free to self-host, with no vendor-enforced session caps or per-seat license fees.
TraceUX.dev's answer:
TraceUX combines session replay, in-product feedback, announcements, browser logs, and backend performance insights in one self-hosted dashboard. It runs as a single Go binary with SQLite and an embedded dashboard, without requiring a separate database or a stack of services. Feedback can be linked to the session that produced it, connecting what users report with what actually happened.
