Microsoft DevSkim review
A free, developer-focused source-code analyzer with IDE extensions and GitHub workflow support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Microsoft DevSkim is an open-source framework for detecting security issues in source code during development and automated workflows. It is designed for developers who want inline security analysis in Visual Studio or Visual Studio Code, along with cross-platform command-line scanning through .NET. Its free plan and self-hosted deployment model suit teams seeking developer-facing checks without a commercial tier structure.
DevSkim fits development environments that already use Microsoft IDEs or GitHub workflows. The Visual Studio and Visual Studio Code extensions provide inline findings, while the command-line analyzer supports Windows, macOS, and Linux. GitHub Actions can run scans, and results can be published to GitHub Security Issues. Output is available in SARIF and text formats, helping connect findings with development and CI workflows. Built-in and custom rules, including JSONPath-, XPath-, and YmlPath-based rules, give teams control over how checks are defined.
The standout feature is its remediation-oriented feedback. Findings include information and remediation guidance, and rule fix-it records support more actionable correction workflows. Optional suppression allows teams to manage findings that do not fit their context. DevSkim is a strong choice for developers who want free inline source-code guidance, custom rule support, and GitHub-compatible automation. Teams seeking a broader SAST platform with a wider verified feature and integration scope should consider alternatives designed for more expansive application-security programs.
