Semgrep is a fast, open-source, static analysis tool that searches code, finds bugs, and enforces secure guardrails and coding standards. Semgrep supports 30+ languages and can run in an IDE, as a pre-commit check, and as part of CI/CD workflows.
Semgrep is semantic grep for code. While running grep “2” would only match the exact string 2, Semgrep would match x = 1; y = x + 1 when searching for 2. Semgrep rules look like the code you already write; no abstract syntax trees, regex wrestling, or painful DSLs.
Semgrep Code supports 30+ languages, including:
Apex · Bash · C · C++ · C# · Clojure · Dart · Dockerfile · Elixir · HTML · Go · Java · JavaScript · JSX · JSON · Julia · Jsonnet · Kotlin · Lisp · Lua · OCaml · PHP · Python · R · Ruby · Rust · Scala · Scheme · Solidity · Swift · Terraform · TypeScript · TSX · YAML · XML · Generic (ERB, Jinja, etc.)
Semgrep Supply Chain supports 12 languages across 15 package managers, including:
C# (NuGet) · Dart (Pub) · Go (Go modules, go mod) · Java (Gradle, Maven) · Javascript/Typescript (npm, Yarn, Yarn 2, Yarn 3, pnpm) · Kotlin (Gradle, Maven) · PHP (Composer) · Python (pip, pip-tool, Pipenv, Poetry) · Ruby (RubyGems) · Rust (Cargo) · Scala (Maven) · Swift (SwiftPM)
