Semgrep vs Snyk Code
Four of fourteen models named Semgrep first on the direct prompt; four named Snyk Code. Both were named by all fourteen models and Semgrep carries 63 labels and Snyk Code 41, so the shares are not directly comparable.
Named in three categories this edition.
Named in one category this edition.

Share is the count of first choices across the direct, paraphrase, budget and scale prompts over all fourteen models, for a mid-market B2B company; rank is within the category; every quote names the model and the prompt it came from. Both figures come from the static application security testing page.

Every negative label with a quote, up to three, then the highest-weighted positives, up to three. Six of seven in this category shown.
“Semgrep OSS and Bandit are fast and low false-positive for obvious patterns, but miss vulnerabilities that span multiple functions... insufficient as sole nightly security scanners” Muse Glimmer 30B · negative prompt · soft negative
“Semgrep Community Edition as your only deep security scanner: It can be useful for fast checks and custom rules, but its analysis is limited to a file/function context” GPT-6 Luna · negative prompt · soft negative
“Checkmarx, Veracode, and Semgrep have all struggled with this because their rule-based engines flag anything that could be a vulnerability” Claude Haiku 4.5 · negative prompt · soft negative
“Semgrep as the primary scanner across all languages... For most budget-constrained companies, Semgrep OSS + SonarQube Community Edition... is the most commonly recommended starting point” Muse Glimmer 30B · budget prompt · first choice
“Tools like Semgrep are generally preferred for modern CI/CD because they are lightweight, customizable, and run significantly faster.” GLM 4.7 FlashX · negative prompt · first choice
“look for developer-friendly alternatives like Semgrep, where rules are written in YAML and read like standard code” Gemini 3.5 Flash · negative prompt · first choice
What the models said about Snyk Code
Every negative label with a quote, up to three, then the highest-weighted positives, up to three. Four of five in this category shown.
“Choose Snyk Code only if you already use Snyk Open Source/Container SCA...The limitation is fewer supported languages than SonarQube/Semgrep and no custom rule authoring.” Muse Glimmer 30B · direct prompt · soft negative
“I'd recommend Snyk Code as a top choice based on recent analyst reports (Forrester Leader), reviews, and pricing.” Grok 4.20 · direct prompt · first choice
“Choose Snyk Code if your primary goal is developer adoption and you want a frictionless, speedy security tool” Gemini 3.5 Flash · comparative prompt · first choice
“using a developer-first tool (like Snyk or GitHub Advanced Security) for fast, early feedback during coding” Qwen 3.7 Flash · comparative prompt · first choice
