What's Good
Session replay shows exactly what happened. Error tracking with context. Log aggregation included. Open-source means self-hosting is possible.
The Catch
License: the core is Apache-2.0, but the enterprise/ and highlight.io/ directories carry their own licenses — not every part of the repo is permissive. Newer than established players. Self-hosting requires significant infrastructure. Some features are less mature.
Verdict
Open-source alternative covering replay, errors, and logs.
