Snyk vs AI Code Auditing: What Each One Actually Checks
Snyk and Launch Ready Code address different failure surfaces. Choosing between them is a false trade-off; the right question is which one addresses the surface you actually need to cover right now.
What Snyk covers
Software Composition Analysis (SCA): Snyk’s core feature. It checks your package.json, requirements.txt, Gemfile.lock, and other lockfiles against its CVE database. It tells you which packages have known vulnerabilities and suggests upgrades or patches.
SAST (paid): Snyk Code, available on paid plans, scans your source code for dangerous patterns similar to Semgrep. Injection vectors, hardcoded credentials, insecure function usage.
Container scanning: Checks Docker images for vulnerable base images and packages inside the container.
IaC scanning: Checks Terraform, CloudFormation, and Kubernetes configs for misconfigurations.
What Snyk cannot see: anything about your live, deployed application. Snyk does not know whether your Supabase RLS is enabled, whether your app has no rate limiting, whether your security headers are configured, or whether you have error tracking. It sees your code and your configurations. It does not see your live URL.
What AI code auditing (Launch Ready Code) covers
LRC scans your live, deployed application from the outside. It covers security (exposed endpoints, missing headers, rate limiting, platform-specific gaps), reliability (error handling quality, uptime stability), performance (bundle size, Core Web Vitals, server response time), and monitoring (error tracking presence, alerting infrastructure).
What LRC cannot see: your source code. It cannot find an injection vulnerability in your ORM code that only manifests in specific inputs. It cannot check whether your package.json has a vulnerable version of a dependency that is never exposed through the live URL. It sees your deploy, not your code.
Head-to-head: Snyk vs Launch Ready Code
| Capability | Snyk | Launch Ready Code |
|---|---|---|
| Dependency CVE scanning | Yes — core feature | Partial (visible from live URL) |
| Static code analysis | Yes (paid — Snyk Code) | No |
| Live URL / DAST-class scanning | No | Yes — core feature |
| AI-platform-aware scanning | No | Yes — 11 platforms |
| Reliability + performance + monitoring | No | Yes |
| Requires code access | Yes | No |
| Price to start | Free (200 tests/mo) · $25+/mo | Free scan · $499 full audit |
The combination that covers both surfaces
Use Snyk (or npm audit, which is free) for your dependency surface, and LRC for your live-URL surface. The pre-launch flow:
- Run
npm audit --audit-level=highand fix any high/critical CVEs - Push and deploy to your live URL
- Run the free LRC scan on the live URL to catch the deploy-time gaps
This two-step flow takes under five minutes and covers both the code surface (dependencies) and the deploy surface (live URL). The $499 LRC audit adds full coverage on the live URL with specific line-level findings.

Should I use Snyk or Launch Ready Code?
Both, on different surfaces. npm audit (free, built-in) or Snyk handles your dependency CVEs. Launch Ready Code handles what your live app exposes. They are complementary, not substitutes. The dependency surface and the deploy surface are distinct — a clean npm audit does not mean your live app is secure.
Does Snyk check live application security?
Snyk does not scan live running applications. It scans source code, lockfiles, container images, and infrastructure configurations. Live application testing (DAST) is a different product category — tools like OWASP ZAP and Launch Ready Code.
Is Snyk free?
Snyk has a free tier that allows 200 tests per month for open-source dependencies and limited Snyk Code (SAST) scans. The paid plans start at approximately $25/month per developer and add unlimited tests, more SAST rules, and team features.
What does npm audit cover that Snyk does not?
npm audit is a subset of Snyk SCA functionality: it checks the same CVE database for Node.js dependencies. Snyk adds multi-language support (Python, Go, Java, etc.), container scanning, IaC scanning, and the paid Snyk Code SAST. For a project using only Node.js, npm audit covers the dependency CVE surface that Snyk SCA covers.
