Feature-by-Feature Comparison
| Feature | Semgrep | Snyk |
|---|---|---|
| Custom Rule Authoring | Industry-leading with intuitive pattern syntax; thousands of community rules available | Limited custom rule capabilities focused on policy enforcement |
| Scan Speed | Extremely fast incremental scanning; sub-second for targeted rule sets | Fast, but heavier scans for full SCA and container analysis |
| SCA | Semgrep Supply Chain provides reachability analysis to reduce false positives | Mature SCA with proprietary vulnerability database and automated fix PRs |
| Container Scanning | No container image scanning capability | Full container image vulnerability scanning with base image recommendations |
| IaC Security | No dedicated IaC scanning module | Terraform, CloudFormation, Kubernetes, and ARM template scanning |
| Language Support | 30+ languages supported with consistent pattern-matching analysis depth | Broad coverage across major languages with varying analysis depth |
| Automated Remediation | Fix suggestions in findings; autofix available for select rules | Automated fix PRs with upgrade and patch suggestions for dependencies |
| Open Source | Core engine is open source (LGPL-2.1); commercial tiers for team features | Proprietary platform with free tier |
| Secrets Detection | Built-in secrets scanning with customizable patterns | Basic secrets detection in repositories |
| CI/CD Integration | CLI-based integration for any CI/CD; native GitHub and GitLab support | Native plugins for GitHub, GitLab, Jenkins, Azure DevOps, Bitbucket |
