Lightweight static analysis for many languages. Find bugs and enforce code standards.

---

Semgrep is a fast, open-source, static analysis tool for finding bugs and enforcing code standards at editor, commit, and CI time.

Semgrep analyzes code locally on your computer or in your build environment: **code is never uploaded**.

Its rules look like the code you already write; no abstract syntax trees, regex wrestling, or painful DSLs. Here's a quick rule for finding Python `print()` statements, run it online in Semgrep's Playground by clicking the image:

To install Semgrep use Homebrew or pip, or run without installation via Docker:

# For macOS
$ brew install semgrep

# For Ubuntu/WSL/Linux/macOS
$ python3 -m pip install semgrep

# To try Semgrep without installation run via Docker
$ docker run --rm -v "${PWD}:/src" returntocorp/semgrep --help
