Semgrep

Lightweight static analysis tool that finds bugs and enforces code standards using simple, pattern-based rules.

Architecture
Pattern-matching engine that runs locally or in CI. Users write rules in a YAML-based DSL that resembles the target language. Supports custom rules and a community registry of 2000+ rules.
Performance
Very fast — analyzes most repositories in under a minute. No compilation required, works on partial code.
Learning Curve
Low
Ecosystem
High

What Is Semgrep?

Lightweight static analysis tool that finds bugs and enforces code standards using simple, pattern-based rules It is supported by a strong and active community ecosystem with a low learning curve.

How Semgrep Works

Pattern-matching engine that runs locally or in CI. Users write rules in a YAML-based DSL that resembles the target language. Supports custom rules and a community registry of 2000+ rules.

Key Use Cases

  • Custom security rule enforcement
  • Code pattern detection and linting
  • Vulnerability detection in CI/CD
  • Enforcing coding standards at scale
  • Secrets detection in source code

When to Use Semgrep

Semgrep is a strong choice when your project requires Custom security rule enforcement, Code pattern detection and linting, Vulnerability detection in CI/CD. In terms of runtime performance, Semgrep features very fast — analyzes most repositories in under a minute. No compilation required, works on partial code.
