Semgrep
Semgrep is an AI-powered Development tool — AI static analysis and code security scanner. Best for: Code Generation & Code Review. Pricing: Freemium (GateOnAI Score: 52/100).
AI static analysis and code security scanner
Scans source code for patterns that indicate bugs, insecure practices, and policy violations. It supports over a dozen languages including Python, JavaScript, Go, and Java, letting teams enforce consistent standards across heterogeneous stacks. Users write custom rules in a simple YAML syntax or adopt the extensive public rule library maintained by the community. The engine runs locally, providing fast feedback without sending proprietary code to external servers. Semgrep’s rule engine combines abstract syntax tree parsing with pattern matching, delivering precise locations for each finding. Integrates with CI/CD pipelines such as GitHub Actions, GitLab CI, and Jenkins, allowing automated scans on each pull request. Generates SARIF and JSON reports that feed directly into security dashboards or code review tools. Provides IDE extensions for VS Code, JetBrains, and Sublime, surfacing findings as you type. Supports incremental scanning to analyze only changed files, reducing runtime on large monorepos. Enterprise tier adds a centralized policy server, role‑based access control, and detailed compliance metrics for standards like OWASP Top 10 and PCI DSS. Designed for developers, security engineers, and compliance officers who need actionable code insights without heavy infrastructure. The free tier offers unlimited local scans and access to the public rule set, sufficient for most open‑source projects. Paid subscriptions unlock cloud‑hosted rule management, team dashboards, and priority support, positioning Semgrep against tools like SonarQube and CodeQL that require separate servers or licensing. Because analysis runs locally, sensitive code never leaves the environment, a key advantage for regulated industries. Documentation includes quick‑start guides, rule‑authoring tutorials, and a community forum for troubleshooting.
