A free, anonymous Black Duck alternative for dependency scanning

By Rushabh Shah, Senior Software Developer · 2026-09-02

Black Duck (part of Synopsys) is built for large-scale enterprise governance — binary and code-snippet-level open-source detection, a deep license-compliance knowledgebase, and multi-team policy rollouts. Real value if you're standing up an org-wide SCA program. But if you just want to check a project's dependencies right now, Black Duck means a sales call, an account, and an onboarding process before you see a single finding.

DepWarden is a free, anonymous alternative for that faster path. Paste a manifest, a lockfile, or an SBOM — or point it at a public repo — and get results in seconds, in a private, session-isolated workspace. No account, no sales call, and it never receives your source code or compiled binaries, only the dependency manifest text.

Exploitability-first prioritization, not a CVE dump

Every component is checked against the full OSV mirror, then enriched with CISA KEV (actively exploited) and FIRST EPSS (exploit probability) — so you get a short "fix these first" list instead of hundreds of undifferentiated CVSS scores.

What Black Duck does that DepWarden deliberately doesn't

To be fair: Black Duck can identify undeclared open source from binary artifacts and copy-pasted code snippets — real value no manifest-based scanner (this one included) can match — plus a mature license-compliance knowledgebase and audit trails built for large, multi-team organizations. If that's the job, Black Duck is built for it.

What DepWarden covers on every scan, free

Typosquat and dependency-confusion detection, OpenSSF Scorecard health, deprecated and end-of-life packages, plus a full compliance round-trip — ingest an existing CycloneDX or SPDX SBOM, export a CycloneDX SBOM, an OpenVEX document, and a NOTICE / license-obligations file. No add-on module, no gated tier.

Repeat scans with no account

Connect a GitHub, GitLab, Bitbucket or Azure DevOps repo branch with a personal access token and attach a schedule — daily, weekly or monthly — and DepWarden re-scans it automatically and emails a report. No token retained beyond the scan.

Try it: paste a pom.xml or package-lock.json and see prioritized findings in seconds — no sign-up. Full feature-by-feature breakdown: DepWarden vs Black Duck.
