Linkerd - Service mesh for Kubernetes - 2025

A different kind of service meshUltra light, ultra simple, ultra powerful. Linkerd adds security, observability, and reliability to Kubernetes, without the complexity. CNCF-hosted and 100% open source.

Instant platform health metricsInstantly track success rates, latencies, and request volumes for every meshed workload, without changes or config. Simpler than any other meshMinimalist, Kubernetes-native design. No hidden magic, as little YAML and as few CRDs as possible.

Zero-config mutual TLSTransparently add mutual TLS to any on-cluster TCP communication with no configuration. Designed by engineers, for engineersSelf-contained control plane, incrementally deployable data plane, and lots and lots of diagnostics and debugging tools. Drop-in reliability featuresInstantly add latency-aware load balancing, request retries, timeouts, and blue-green deploys to keep your applications resilient.

State-of-the-art ultralight Rust dataplaneIncredibly small and blazing fast Linkerd2-proxy micro-proxy written in Rust for security and performance. Linkerd is a service mesh for Kubernetes. It makes running services easier and safer by giving you runtime debugging, observability, reliability, and security-all without requiring any changes to your code.
