Open‑source session replay and error monitoring. Record user sessions to replay and debug issues. Self‑hostable, with a free cloud tier.
Highlight.io is an open‑source session replay and error monitoring platform. It records user clicks, scrolls, and inputs, letting you replay sessions to see exactly what happened before an error.
I added Highlight.io to an e‑commerce site. A user reported a payment failure; I watched the replay and saw they accidentally clicked an element that broke the form. Fixed it quickly. This insight is impossible with logs alone.
Highlight.io makes reproducing frontend bugs trivial—no more asking “What did you do?”
Pro tip: Highlight.io can redact sensitive data (passwords, credit cards) to protect user privacy.
