Holger guards your artifacts at rest

Immutable artifact repository in pure Rust.

GATLING — one all-core engine · zero rayon · zero-copy · ~11/12 cores

  • Airgap: transfer from internet, Nexus, Artifactory → immutable znippy archive
  • Versioned: atomic transactions, content-addressed (Blake3), O(1) file random access
  • Extreme performance: Apache Arrow zero-copy, multi-core parallel I/O
  • Zero dependencies: no OS packages, no shell, no Python — 100% Rust (even decompressors rewritten from C)
  • Embeddable: runs on bare-metal/OS-free devices, 2 MB RSS

Biggest gap — p999_ms: holger leads nexus by 17.2× (0.44 vs 7.60).

holger vs Nexus vs Artifactory, served over HTTP on all sides, measured identically. Fair hardware — no throttled rival: each JVM competitor gets all 12 cores + ~48 GiB RAM (75 % of the 64 GiB host) + a 24 GiB fair JVM heap; holger runs in-process on the same 12 cores. Full method + every metric: README-full.
