In their own words
OpenGrep
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.
Puma Scan
Puma Scan is a static application security testing tool for C# code in Visual Studio. Its End User Edition scans code as developers write and reports vulnerabilities as compiler warnings before a commit. The extension supports C# in.NET Framework and.NET Core, including Web Forms and MVC; legacy website projects are unsupported. The product page says it also scans AI-generated code from GitHub Copilot, Cursor, Claude, ChatGPT, Amazon Q and Gemini Code Assist. For automated scanning, listed integrations include GitHub Actions, GitLab CI and Azure DevOps. CI editions can enforce configurable vulnerability severity thresholds and stop builds when requirements are not met. The Server Edition supports command-line scans, on-premises Azure DevOps build tasks and exports in HTML, JSON, MSBuild, VSO, VSTest and CSV formats. Community is free. End User costs $299 a year; Server is $4,999 a year, Cloud CI Standard $5,999 a year and Cloud CI Unlimited $10,999 a year. Trials last 30 days, require no credit card and do not include reporting. Community analyzers run locally and do not contact Puma Scan servers for rule updates.
