Why I replaced Nexus with a 32MB binary

Every artifact registry I've used is bloated. Nexus wants 4GB RAM. Artifactory is even heavier. I just want to store Docker images and Maven JARs. So I built NORA — a multi-protocol artifact registry in Rust. The numbers NORA : Startup <3s, RAM <100MB, Image 32MB, MIT license Nexus : Startup 30-60s, RAM 2-4GB, Image 600MB+, EPL/Commercial Artifactory : Startup 30-60s, RAM 2-4GB, Image 1GB+, Commercial What it does One binary handles all of these: Docker Registry v2 — full OCI spec, pull-through cache for Docker Hub/GHCR Maven — host JARs + proxy to Maven Central npm — private packages + proxy to npmjs.org Cargo — Rust crates hosting PyPI — pip-compatible index Try it in 10 seconds docker run -p 4000:4000 ghcr.io/getnora-io/nora:latest Open http://localhost:4000/ui/ — that's it. Tech stack Built with Axum + Tokio. No database — just filesystem or S3. AtomicU64 for lock-free metrics, Tower middleware for auth and rate limiting, streaming uploads with async background caching.
