I'm knee-deep in trying to get a proper security scan pipeline going for our containerized workloads, and the tooling landscape is… well, it's a mess of overlapping claims. Everyone says they do everything.
So, Snyk. Their marketing heavily pushes "developer-first security," and their IaC, container, and open-source dependency scanning is clear. But when it comes to **static code analysis for custom business logic** (SAST), I'm getting mixed signals.
From what I can piece together:
* Snyk Code **does** offer SAST-like capabilities, finding issues like hardcoded secrets, SQL injection, etc. in your own source code.
* But its depth seems tuned for speed and dev feedback, not necessarily the comprehensive, language-specific rule sets you get from a dedicated SAST tool (like SonarQube, Checkmarx, or Semgrep).
My burning question is this: In a real-world, cost-conscious setup, are teams using Snyk Code **as their sole SAST tool**, or is it primarily for the dependency/container stuff, with a "proper" SAST tool still running alongside it?
The vendor lock-in angle here is real. If Snyk becomes your one-stop shop, you're buying into their entire ecosystem. But if it's just a complement, then the cost-benefit math changes.
Example scenario: A Python/Go microservice repo. Would you run only Snyk (for SCA, containers, *and* code), or Snyk for SCA/containers + Semgrep for SAST?
Looking for practical experiences, especially where someone actually tried to decommission their old SAST tool.

Every cloud has a dark cost.
You've hit the nail on the head about the depth being tuned for speed. In my experience, Snyk Code is fantastic for catching the high-severity, obvious stuff fast - the secrets, the simple injections. It gets those fixes into the developer's workflow immediately.
But we still run a dedicated SAST tool (Semgrep in our case) for the deeper, language-specific rules and compliance checks. It finds the weird edge cases Snyk misses. So for us, it's absolutely a complement. The vendor lock-in fear is real though - once their container and SCA are baked in, it's hard to walk away.
Have you looked at how their API handles merging results from multiple tools? That was a deciding factor for our stack.
You're right to question the "sole SAST tool" claim. In every production environment I've seen or managed, Snyk Code functions as a first-pass filter. It catches the glaring, high-confidence vulnerabilities early in the dev cycle, which is valuable for workflow integration. However, it consistently misses nuanced logic flaws, complex data flow issues, and language-specific quirks that dedicated SAST tools are built to find.
Your cost-conscious setup angle is the key. If you're trying to optimize, you need to ask what you're securing. For a greenfield microservice with limited custom logic? Maybe Snyk is enough. For a legacy monolith with critical business rules? Running Snyk *and* a dedicated SAST tool isn't redundancy, it's necessary coverage. The lock-in cost is less about the tool and more about the gaps you'll inevitably have to accept.
Measure twice, migrate once.
