It's a split decision.
SonarQube and Nexus Repository solve different problems. SonarQube checks code for quality, security and compliance, with quality gates and verified pull-request fixes. Nexus Repository stores software components and models, with controls for artifact access and protection against malicious packages in paid tiers. Pick SonarQube to govern code changes; pick Nexus to manage the dependencies and artifacts moving through builds. Both offer cloud and self-hosted options, but their pricing units and usage limits are not directly comparable.

02Pricing at real usage
SonarQube's free Developers plan covers up to 50k private LOC, and its OSS plan is free for public, OSI-licensed repositories. The Team plan starts at $34 per month and includes up to 100k private LOC at that price; the pricing page lists no annual Team price. Enterprise is annual and quote-based. Advanced Security requires an additional subscription, with no published price.
Nexus Repository has a free self-hosted Community Edition. Cloud Pro is $1,950 per year, equivalent to $162.50 per month, and includes 25 GB of consumption. Additional usage costs $1.10/GB/month for 0–1,000 GB and $0.90/GB/month for 1,001–2,500 GB; higher usage requires contacting sales. Self-Hosted Pro is $7,500 per year and includes 50K components and 15M monthly requests. Pro+ and Enterprise pricing is custom. Both vendors bill some paid plans annually, so compare actual LOC or artifact usage before budgeting.
03API, SDKs and integration
SonarQube's homepage lists Claude Code, Cursor, Devin, GitHub Copilot, Antigravity and Codex integrations. Its product workflow includes quality gates and a Remediation Agent that opens verified pull requests. The vendor doesn't publish API or SDK details in its listed integration information, so confirm endpoints, authentication and supported languages before making SonarQube part of an automated workflow.
Nexus Repository lists Maven, Hugging Face, PyPI, npm and NuGet support, plus Jenkins, GitHub Actions and GitLab CI/CD integrations. Paid editions include an Audit Log API. The vendor doesn't publish SDK details in its listed integration information. The available integration lists make Nexus the clearer fit for package and CI/CD workflows; SonarQube's named integrations target coding assistants. Ask both vendors about API access, pagination, rate limits and export support, and verify which integrations are included in the edition you plan to deploy.
04Open source, self-hosting and lock-in
Both products offer self-hosted options. SonarQube is available as Server or Cloud; Nexus Repository has a self-hosted Community Edition and paid self-hosted editions, as well as Cloud plans. A free Community Edition does not by itself establish an open-source license: neither vendor states an open-source license for these products in the stated product facts. Check the license terms for the exact edition before modifying or redistributing it.
The vendors don't publish data-export specifics in the stated product facts. Before adoption, ask how to export project findings, repository metadata, blobs and audit records, and whether export requires a paid tier. Nexus migrations may involve transferring stored components and changing client repository URLs; SonarQube migrations may involve preserving project configuration and quality-gate rules. Confirm supported formats and migration services with the vendor before setting retention or exit plans.
Questions people ask
Are SonarQube and Nexus Repository alternatives?
No. SonarQube verifies code for quality, security and compliance. Nexus Repository stores and manages software artifacts and components. A team may use both: SonarQube checks changes, while Nexus Repository provides a repository for dependencies and build artifacts.
Which product has a free plan?
Both do. SonarQube offers free private-project analysis up to 50k LOC and a free plan for public, OSI-licensed repositories. Nexus Repository has a free self-hosted Community Edition. Their free tiers cover different workloads, so compare the relevant limits and edition features.
Can I self-host SonarQube or Nexus Repository?
Yes. SonarQube offers Server alongside Cloud. Nexus Repository offers a self-hosted Community Edition and paid self-hosted Pro, Pro+ and Enterprise editions, as well as cloud plans. Check the edition requirements and pricing before choosing a deployment.
Which should I use to secure dependencies?
Nexus Repository is the artifact repository option, and its Pro+ editions add malicious-package blocking, suspicious-package quarantining and container protection. SonarQube Advanced Security assesses software supply chain and dependencies, but it requires an additional subscription. Choose based on whether you need repository controls, dependency assessment or both.
