PhantomYerra vs Snyk

Snyk is the developer-first benchmark for SAST (Snyk Code) and open-source dependency security (Snyk Open Source). Here is an honest, number-anchored side-by-side - including where Snyk leads.

24,476
Detection rules - far beyond Snyk Code's pattern set
340+
Native MISRA C/C++ rules - Snyk ships none
1,770
AI/LLM rules vs Snyk-AI's ~30
100%
Offline-capable - Snyk is cloud-first
Verdict: PhantomYerra exceeds Snyk on native rule depth, C/C++ + MISRA/CERT, compliance breadth, AI/LLM security, and offline/air-gapped deployment. We are at parity on SCA, SBOM, reachability, typosquat, malicious-package and license auditing. Snyk still leads on developer DX - mature IDE plugins, a polished PR-review bot, and a hosted, always-current vulnerability database.

Where PhantomYerra exceeds

  • Rule depth at a different scale - 23,796 native SAST rules across 13 deep engines, each exceeding the deduped commercial peer total (1.06×–2.45×).
  • Real C/C++ and safety-critical coverage - 10,318 native C/C++ rules plus native MISRA C:2023 / C++:2023, SEI CERT, C++ Core Guidelines. Snyk Code does not target these.
  • 1,770 AI/LLM security rules - prompt injection, model-loading RCE, LLM key leakage, vector-DB/RAG and MCP/agent misuse - vs Snyk-AI's ~30.
  • Compliance breadth - 13+ standards mapped per finding so findings become audit evidence automatically.
  • Offline, air-gapped, pure-Python - your source never leaves the host unless you opt into an external AI provider; ideal for regulated and defense environments.
  • Fix-family reports - grouped findings with worked vulnerable→fixed examples instead of per-finding repetition.

Where Snyk still leads (honestly)

  • Developer DX - Snyk's IDE plugins (VS Code, JetBrains) and inline PR-review bot are mature and broad. Our CI/SARIF path is solid; the inline PR bot is maturing.
  • Hosted vuln-DB currency - Snyk's hosted database is continuously updated. We mirror OSV / NVD / GHSA with daily auto-refresh, which is excellent but operator-hosted.
  • Reachability ergonomics - Snyk's reachability is a polished, broadly-languaged killer feature with years of UX. Ours now covers every supported ecosystem (11 language families) and is offline; Snyk's hosted graph and presentation are still more refined.
  • Brand-wide ecosystem - marketplace integrations and a large plugin catalog built over years.

At parity on SCA, SBOM, reachability (all supported ecosystems), typosquat, malicious-package and license auditing. Every "Yes" is verifiable against the v51.2.0 source tree; rule counts are produced by re.findall over the scanner files.

Bring it in-house

If you need deep C/C++, native compliance, AI/LLM coverage, and a scanner that runs fully offline - run PhantomYerra on your own tree and compare.
