Introduction

Pixie provides instant Kubernetes-native application observability. It uses eBPF to automatically capture telemetry such as protocol traces, resource metrics and application profiles, with no manual instrumentation, and stores data in the cluster. It is a CNCF sandbox project originally created by Pixie Labs and contributed by New Relic.

The source code is at pixie-io/pixie on GitHub under the Apache-2.0 licence, with about 6,600 stars; the most recent commit was on 9 November 2026.
