What is Semgrep?
Semgrep is a fast, open-source static analysis engine that enables developers and security teams to write custom rules for finding bugs, enforcing coding standards, and detecting security vulnerabilities. Its pattern-matching syntax is designed to be intuitive for developers, reading like the code it matches. Semgrep's commercial platform (Semgrep AppSec Platform) adds managed rules, a web dashboard, SCA capabilities, and secrets detection, making it a comprehensive alternative for teams that value rule customizability and fast scan performance.
Best for: Security-conscious development teams that want fast, customizable static analysis with the ability to write organization-specific security rules
