    score / 100

    Why switch from Linkerd

    Covers VMs and other runtimes too, and adds service discovery over DNS and a key/value store.

    Pros

    • Works across VMs, Kubernetes, ECS and Nomad from one control plane
    • Service discovery over plain DNS needs no app changes
    • Built-in key/value store and health checks
    • Single binary that is easy to try in developer mode

    Cons

    • Source-available under the Business Source License since 2023, not OSI open source
    • Multi-tenancy and governance features need the paid Enterprise edition
    • Running a Raft server cluster adds operational work
