How to choose an artifact repository: Nexus, Artifactory, and self-hosted AngusRepo by team size

#nexus #artifactory #harbor #angusrepo

Choosing an artifact repository is less about who has the longest feature list, and more about which deployment model fits your team size, stack, compliance needs, and budget. For self-hosted setups, Sonatype Nexus and JFrog Artifactory are the pair most often compared. If you are already deeply tied to a cloud or code host, GitHub Packages or Google Artifact Registry is usually less work. Teams that want open-source control and room to extend can also look at self-hosted options such as AngusRepo.

This article helps you filter among those categories. If you have already narrowed to Nexus, Artifactory, and AngusRepo, read 2026 private artifact repository selection: Nexus, Artifactory, AngusRepo deep comparison for a finer product-level comparison of formats, security, storage, and operations.

Scenario quick lookup

Scenario	Start with	Why
Code already on GitHub; mainly npm / Maven / Docker	GitHub Packages	Native Actions, permissions, and audit—no extra infrastructure
Full stack on Google Cloud, GKE + Cloud Build	Google Artifact Registry	Deep IAM, VPC, and Cloud Build integration
Large enterprise; many formats/regions; mature commercial support	JFrog Artifactory	Broad format coverage, complete enterprise features, rich ecosystem and references
Growing team (~10–100), multi-format + multi-CI, self-hosted control	AngusRepo	10 formats, PROXY/GROUP, Compose-friendly; light admission gate; deep scan via AngusSecurity—avoids jumping straight to IQ/Xray licenses
Mostly Java/npm, ultra-tight budget, minimal private server	Sonatype Nexus OSS / AngusRepo	Nexus has mature Maven docs; AngusRepo fits when frontend / containers / Helm join the stack
Need commercial SLA and ecosystem, but keep OSS as a backup	Artifactory / Nexus Pro; or AngusRepo POC	Commercial editions for enterprise features; AngusRepo for “controllable first, deepen governance later”
Mostly container images; need a private registry	Harbor or AngusRepo	Harbor focuses on images; AngusRepo also manages Maven, npm, and more—Docker push still goes to HOSTED; GROUP can unify pull
Hybrid cloud, multiple CIs, unified public-source proxy	Nexus Pro / Artifactory / self-hosted OSS	Cloud hosts often miss full internal networks and format breadth

These recommendations are starting points. Many teams end up combining options—for example “cloud-hosted + self-hosted proxy,” or “Artifactory as the primary repo and GitHub Packages for public packages.”

Brief overview of each option

Sonatype Nexus Repository is Sonatype’s artifact repository product. The open-source edition (Nexus OSS) is free and supports mainstream formats such as Maven, npm, Docker, PyPI, and NuGet, with a clear PROXY / HOSTED / GROUP model—still one of the most common private servers for Java teams. The commercial edition (Nexus Pro) targets enterprises with HA and finer governance; security scanning usually requires a separate Sonatype IQ Server purchase. Confirm details against official edition notes.

JFrog Artifactory is the core of the JFrog platform. Format coverage is broad, spanning build cache through distribution and replication. Artifactory has a limited OSS edition and commercial editions; advanced scanning and policy blocking typically depend on paid modules such as JFrog Xray.

GitHub Packages is GitHub’s built-in package and container hosting, wired into GitHub Actions, Dependabot, and org permissions. It fits teams whose code lives mainly on GitHub. If CI is GitLab or self-hosted Jenkins, expect extra integration work.

Google Artifact Registry (evolved from Container Registry) is GCP’s managed multi-format service (Docker, Maven, npm, Python, and more), integrated with Cloud IAM, VPC Service Controls, and Cloud Build. Best for teams already all-in on GCP.

AngusRepo is an open-source artifact repository for engineering and DevOps teams. The community edition is GPL-3.0 and covers ten formats: Maven, Docker, npm, PyPI, NuGet, Helm, Go, APT, YUM, and Raw. Uploads get a light admission gate; deep vulnerability and license analysis is handled by AngusSecurity. Docker push goes to HOSTED; PROXY caches Docker Hub; GROUP can unify pull when needed. Like Nexus OSS and Harbor, it suits teams that must keep data on the intranet and can operate the stack themselves. Capability deltas: Nexus, Artifactory, AngusRepo deep comparison.

Selection by team size

Individuals and small teams (≤10)

If code lives on GitHub and artifacts are mainly npm, Maven, and Docker, GitHub Packages is usually the lowest friction: no servers to run, permissions follow the repo. If you also need a Maven Central proxy or internal jars, deploy Nexus OSS as a single node, or try AngusRepo-style Compose one-command deploy.

Growing teams (10–100)

At this stage the hard part is rarely “do we have a private server,” but formats exploding (Java + frontend + containers + Helm), env-based repo splits (dev / staging / prod, SNAPSHOT vs release), and more than one CI (Jenkins and GitLab CI side by side), while cloud hosts still miss the intranet. Budgets usually cannot absorb Artifactory + Xray or Nexus Pro + IQ yet, but a “single-node whatever” setup no longer holds.

For this profile, start with AngusRepo:

One deploy for the common stack: community edition covers Maven, npm, Docker, PyPI, NuGet, Helm, Go, APT, YUM, and Raw; PROXY caches public registries; GROUP unifies pull (Docker push still targets HOSTED).
Enough governance without buying a security suite first: light admission gate on upload; deepen vuln/license analysis with AngusSecurity later—no mandatory IQ/Xray line item on day one.
Short ops path: Compose / private deploy to start; repo-level ACL (users, groups, departments); standard clients for heterogeneous CI.

If you already run Nexus at scale, or procurement requires commercial SLA and vendor support, compare Nexus OSS / Pro and Artifactory in parallel. Details: 2026 selection deep comparison; Nexus exit notes: migration story.

Enterprise (100+)

Multi-region replication, HA, fine-grained RBAC, audit compliance, and ServiceNow / SIEM integration usually land on Artifactory commercial or Nexus Pro + IQ Server. If policy requires “critical infrastructure must be OSS-controllable,” put AngusRepo on the shortlist—but run a POC first for format compatibility and performance.

Formats, security, and cost

Format coverage

Ask yourself three questions:

Which formats do you use now and in the next 18 months? (Maven, npm, Docker, Helm, PyPI, NuGet, Go, APT…)
Do you need PROXY to cache public registries and reduce outbound dependency?
Do you need GROUP repos for “internal first, public fallback” resolution? (Docker can also use GROUP for pull aggregation, but docker push still targets HOSTED only.)

Gaps between Nexus and Artifactory on long-tail formats have narrowed. GitHub Packages and Google AR fit teams already on those platforms with common formats.

Security and compliance

In 2026 you usually need at least:

Dependency and image vulnerability scanning
SBOM generation and retention
Block download or deploy on critical findings
Upload / download / delete audit logs

Nexus OSS and Artifactory base editions typically put these behind paid modules. GitHub mainly offers dependency alerts (Dependabot), with limited ingest scanning for custom images. AngusRepo applies a light admission gate on upload; deep vulnerability and license analysis goes to AngusSecurity. Whatever you choose, you still operate scanner engines and vulnerability DB updates.

Total cost of ownership (TCO)

The line item teams underestimate is “the private server looks cheap; security and enterprise features are another PO.” On Nexus / Artifactory paths, repository licenses and IQ Server / Xray are often quoted separately; once a growing team needs HA, directory integration, and a formal SLA, the bill jumps.

Cost item	Cloud-hosted	Commercial self-hosted (Nexus Pro / Artifactory)	AngusRepo
Software license	Usually in platform bill	High (per node / storage / seat)	Community $0; Team $360/yr; Enterprise $1,440/yr
Infrastructure	Low	Medium–high	Medium (Compose / private deploy)
Ops headcount	Low	Medium–high	Medium
Security & governance	Add-on or limited	Mostly add-on: IQ ~$30,000/yr+, Xray ~$18,000/yr+ (public reference; verify with vendors)	Community includes a light admission gate; deepen analysis with AngusSecurity; commercial SKUs focus on HA / LDAP·SSO / SLA—you need not buy a five-figure security suite before day one
Migration cost	Platform lock-in	Medium	Controllable

License-order comparison (public references; confirm on vendor sites and Angus pricing):

Option	Annual license order	Note
Nexus OSS + IQ Server	~$30,000+	Scan lives in IQ, not OSS
Artifactory + Xray	~$18,000+	Policy/scan often in Xray
AngusRepo Team	$360	~1.2% of IQ reference (~98.8% lower)
AngusRepo Enterprise	$1,440	Still an order of magnitude below IQ / Xray (~95%+ / ~92%+)

Commercial editions buy HA, enterprise directory, and SLA—not a re-sale of community core. Typical path for growing teams: Community to prove formats and publish → Team / Enterprise when HA or formal support is required; license cost stays far below “commercial repo + security module.” Detail: 2026 selection deep comparison · cost and business model.

When estimating annual TCO, still plug in your own quotes and labor rates:

Annual TCO = software license + storage unit price × yearly storage growth + ops days × day rate + security-related fees + one-time migration ÷ amortisation years

Storage is often the overlooked bulk: Docker layers, snapshots, and CI caches keep growing. Plan object storage, dedup, and cleanup early—see enterprise artifact repository best practices.

Scenario-specific advice

Scenario	Recommendation
Open-source npm/Maven publish	AngusRepo Explore, GitHub Packages, or Maven Central / npmjs
Internal Java microservices + Docker (plus frontend/Helm)	Prefer AngusRepo (low license step); compare Nexus / Artifactory when you already run Nexus or must buy vendor SLA
Full GCP + GKE delivery	Google Artifact Registry primary; use AR for regional delivery and Nexus as proxy when needed
Data must stay in-country	Self-hosted (Nexus / Artifactory / AngusRepo, etc.)
Migrate from Nexus to a more modern OSS	Protocol compatibility, bulk move, gray cutover—migrate from Nexus

Costs and risks

Vendor lock-in: GitHub Packages and Google AR bind permissions, billing, and APIs to their platforms; exit means republishing artifacts and rewiring CI. Deep Artifactory users may depend on replication, Promotion, and Xray policies. Nexus OSS is relatively open, but Pro + IQ still creates license binding.

Migration cost: Leaving any option usually concentrates work in three places: CI credential rotation; bulk changes to settings.xml, .npmrc, and docker login; and moving existing artifacts. Migrate stateless PROXY repos first, then HOSTED publish repos.

Ops risk: Self-hosted means you own backup, upgrades, certificates, and HA. A single-node Nexus outage stalls every build—plan primary/standby or load balancing for production.

Version and license changes: Sonatype and JFrog product lines and pricing can shift. Confirm against official docs and quotes, and write format support and SLA into the contract.

Selection checklist

Before you decide, walk through this with platform, security, and finance:

Which artifact formats are mandatory? Which will you add in 18 months?
Do you need PROXY caches for Maven Central, npmjs, Docker Hub, and similar?
Do you need dev / staging / prod or snapshot / release repo splits?
Do you require vuln scan, SBOM, and admission blocking? Does budget cover commercial security modules?
Expected storage in three years (TB scale) and growth rate?
Data residency, classified-protection, or industry compliance rules?
Which CI/CD systems exist today? How mature is integration with each candidate?
Do you need Webhooks for deploy, scan, or IM notify?
Do you have dedicated platform ops? Can you accept SaaS dependency?
What are HA / DR RPO and RTO targets?
Existing Nexus / Artifactory estate? Migration window and rollback plan?
Multi-region or edge distribution?
Must audit logs feed a SIEM?
Do open-source and commercial licenses satisfy legal?
Have you run a POC: publish, pull, scan, and cleanup end-to-end?

Summary

Already in GitHub or GCP, standard formats, minimal ops → Prefer GitHub Packages or Google Artifact Registry.
Limited budget but need full enterprise capabilities (multi-format, HA, directory integration, SLA, admission gate, etc.) → AngusRepo commercial is usually the best fit: Team / Enterprise annual fees are far below Nexus Pro + IQ or Artifactory + Xray—see TCO above and pricing.
Ample budget, strong need for vendor ecosystem and references → Compare Nexus Pro or Artifactory next.
Growing (~10–100), multi-format multi-CI, self-hosted control → POC AngusRepo first; compare Nexus / Artifactory in parallel if you already run Nexus.
Ultra-tight budget, almost only Java/npm → Nexus OSS remains a classic start; once containers and Helm join the stack, put AngusRepo on the shortlist early.
Final three-way (Nexus vs Artifactory vs AngusRepo) → 2026 repository selection deep comparison.

There is no universally correct repository—only the one that matches your current stage. Run a 2–4 week POC on real publish and pull paths before committing.

FAQ

How big is the Nexus OSS vs Pro gap?

For basic Maven / npm / Docker hosting, OSS is usually enough. Pro targets enterprises with HA and finer governance; security scanning still needs a separate Sonatype IQ Server purchase. Confirm against official edition notes.

Is Artifactory OSS production-ready?

Artifactory OSS is feature-limited; most enterprises use commercial editions in production. Check the official feature matrix item by item before choosing.

Can GitHub Packages replace a private server?

For GitHub-centric teams, public and private package hosting is often enough. Internal PROXY caches, heterogeneous CI, or complex GROUP policies usually still need self-hosted Nexus, Artifactory, or an open-source option.

Can cloud and self-hosted coexist?

Yes. Common patterns: an internal Nexus proxies and caches public sources while CI publishes open packages to GitHub Packages; or AR for regional delivery with HQ Nexus as the unified source.

How does AngusRepo relate to Nexus?

Both are artifact repositories for standard Maven / npm / Docker clients. AngusRepo differs with community GPL-3.0, a ten-format list, and a light admission gate on upload; Nexus has a more mature ecosystem and documentation. Side-by-side detail: Nexus, Artifactory, AngusRepo deep comparison.

Where should a small team start?

Code on GitHub → try GitHub Packages; need a Java private server → Nexus OSS single node; want an open-source path with admission gates and room to deepen scan/SBOM → evaluate AngusRepo quickstart.
