Overview
Moderne
Moderne is a continuous software modernization platform designed to help you manage large-scale code changes across thousands of repositories simultaneously. Instead of manually fixing security vulnerabilities or updating deprecated libraries one by one, you can use automated 'recipes' to search, transform, and fix your code in minutes. It leverages the OpenRewrite ecosystem to perform type-accurate abstract syntax tree (AST) transformations, ensuring your code remains functional and clean after every automated update.
You can use the platform to automate migration tasks like moving from Java 8 to 17, fixing common security flaws (SAST), and enforcing consistent coding standards across your entire organization. It is built for platform engineering and security teams at mid-to-large enterprises who need to reduce technical debt without slowing down development cycles. By centralizing code analysis and remediation, you gain full visibility into your software inventory and the power to fix issues at the source.
Semgrep
Semgrep helps you secure your code without slowing down your development workflow. You can scan your source code for security vulnerabilities, hardcoded secrets, and logic errors using a fast engine that integrates directly into your CI/CD pipeline. It supports over 30 languages, allowing you to enforce custom coding standards or use thousands of pre-built rules maintained by the security community.
You can manage your security posture from a central dashboard that prioritizes reachable vulnerabilities, ensuring you fix the issues that actually matter. Whether you are a solo developer securing a side project or a large security team managing thousands of repositories, the platform scales to meet your needs with high-speed scanning that provides results in minutes rather than hours.
Overview
Moderne Features
- Automated Code Remediation Apply pre-built OpenRewrite recipes to automatically fix security vulnerabilities and upgrade library versions across all your repositories.
- Mass-Scale Code Search Search through thousands of repositories instantly to find specific code patterns, vulnerable dependencies, or non-compliant configurations.
- Type-Safe Transformations Ensure your automated code changes are accurate and safe with loss-less semantic tree transformations that preserve your code's logic.
- Custom Recipe Builder Create your own automation recipes tailored to your organization's specific coding standards and internal library migration needs.
- Change Campaign Management Track the progress of large-scale refactoring projects and manage pull requests across your entire GitHub or GitLab organization.
- Security Vulnerability Fixing Go beyond just finding bugs by automatically generating and committing fixes for common CWEs and OWASP Top 10 issues.
Semgrep Features
- Code Scanning (SAST). Scan your source code for vulnerabilities and logic errors using a fast engine that supports over 30 popular programming languages.
- Supply Chain Security. Identify vulnerable open-source dependencies in your projects and prioritize fixes for libraries that are actually reachable in your code.
- Secret Detection. Prevent sensitive data leaks by automatically detecting API keys, passwords, and certificates before they are committed to your version control.
- Custom Rule Engine. Write your own security rules using a simple syntax that looks like the code you are already writing every day.
- CI/CD Integration. Automate your security checks by triggering scans on every pull request to catch vulnerabilities before they reach your production environment.
- Reachability Analysis. Reduce developer fatigue by filtering out theoretical vulnerabilities and focusing your team on code that is actually executable and risky.
