OpenGrep
OpenGrep is an open-source static analysis engine for searching source code patterns and identifying security issues.
What OpenGrep is
OpenGrep is an open-source static analysis engine for searching source code patterns and identifying security issues. It runs on Linux, macOS, and Windows and is aimed at developers and organizations analyzing code in their own environment. The project supports more than 30 programming languages, including Python, Java, JavaScript, Go, Rust, PHP, and Visual Basic. Existing Semgrep rules and rulesets work without changes. Its intrafile taint analysis tracks constructor and field assignments, flow between methods, higher-order functions across 12 languages, and collection operations such as map, filter, and reduce. OpenGrep produces JSON and SARIF output and includes a CI subcommand for workflow use. The project distributes self-contained binaries and says its releases are signed with Cosign. It is a fork of Semgrep under the LGPL 2.1 license. The free plan is free, and deployment is self-hosted. Its security policy asks for vulnerability reports by email and lists only the latest version as supported.
Good
- Supports 30+ programming languages.
- Existing Semgrep rules and rulesets work unchanged.
- Produces JSON and SARIF output.
- Includes a CI subcommand.
- Self-contained binaries are available for Linux, macOS, and Windows.
Watch out
- Deployment is self-hosted.
- The security policy supports only the latest version.
Who it suits
OpenGrep suits developers and organizations looking for a free static analysis engine they can run in their own environment. Existing Semgrep rule users can apply those rules without changes.
Verdict
OpenGrep offers broad language coverage, Semgrep rule compatibility, and output formats suited to development workflows. Its self-hosted deployment and latest-version-only support policy are worth weighing before adoption.
