## What it is
Opengrep is an open-source static application security testing (SAST) engine forked from Semgrep under LGPL-2.1, supporting pattern-based code search and taint analysis across 30+ languages. It is Semgrep-rule compatible and outputs JSON and SARIF for CI integration.

## Use cases
- find security vulnerabilities in source code
- run static analysis in CI pipelines
- search codebases with semantic grep patterns
- perform taint analysis to trace untrusted input
- scan code with existing Semgrep rules
- generate SARIF reports for security findings

## When to choose
- you want a fully open-source SAST engine without commercial license restrictions
- you already have Semgrep rules and want drop-in compatibility
- you need taint analysis or language support missing from Semgrep CE (e.g., Visual Basic, Apex, Elixir)

## When to avoid
- you rely on Semgrep's proprietary platform features or commercial rules
- you need dynamic analysis or runtime security testing rather than static analysis

## Facets
- artifact type: cli-tool

- domain: security, developer-tools, testing
