Microsoft DevSkim vs OpenGrep

Microsoft DevSkim is a free, MIT-licensed toolkit for security linting and static source-code analysis. It provides IDE extensions, language analyzers, and rules to help developers identify and address security vulnerabilities early. It includes built-in rules and allows teams to write their own using JSONPath, XPath, and YmlPath. Listed language support includes C, C++, C#, Cobol, Go, Java, JavaScript/TypeScript, and Python, among others. Its cross-platform .NET CLI analyzes files and directories and can be installed as a global tool or obtained as binaries for Windows, macOS, and Linux. A C# library is also available for embedding analysis in other tools. Results can be emitted as SARIF, JSON, or text; the CLI can apply suggested fixes from SARIF results and add suppression comments. The project lists extensions for Visual Studio Code and Visual Studio, and supports CI/CD in self-hosted environments. Support is limited to GitHub issues and project wiki resources. Vulnerability reports should be sent privately to Microsoft's Security Response Center rather than posted publicly.

OpenGrep is a free, open-source static analysis engine for finding security issues and searching patterns in source code. It runs on Linux, macOS, and Windows, with self-hosted deployment. The project supports more than 30 languages, including Python, Java, JavaScript, Go, Rust, PHP, and Visual Basic, and 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 documents a CI subcommand for workflow use. The project distributes self-contained binaries and says releases are signed with Cosign. OpenGrep is a Semgrep fork under the LGPL 2.1 license. The security policy requests vulnerability reports by email and lists only the latest version as supported.
