Console’s review

· Reviewed by David Mytton

What we like

Records production network traffic for reproducing issues later. Stores traffic on disk, S3 (pro version only), Kafka, ElasticSearch, etc. Middleware supports sanitizing sensitive data, emitting metrics, etc. Speed up replay for load testing on real traffic. Transparently captures traffic without affecting it (it’s not a proxy). Open source (some features are paid).

Tradeoffs

Requires sudo by default, but can run as a non-root user or by forwarding traffic to it. Windows is not officially supported.
