Production-Proven Maturity
TraceKit's distributed tracing is mature and battle-tested. Highlight.io is newer with an ambitious scope.
Managed at $29/month
Fully managed APM at $29/month. Highlight.io's cloud starts at $150/month.
Common Highlight.io pain points
Younger Project
Individual features may not match the depth of established tools.
Self-Hosted Complexity
Requires managing ClickHouse, Kafka, and other infrastructure.
When Highlight.io might be a better fit
- You want open-source session replay with self-hosting
- You need session replay, errors, logs, and traces in one open-source tool
- You prefer to run your own infrastructure for data sovereignty
