Opengrep - Open Source Code Security Engine

What is Opengrep?

Opengrep is a fork of Semgrep CE (Community Edition), launched in early 2025 by a consortium including JIT, Aikido Security, Endor Labs, and other companies. It was created in response to Semgrep's licensing changes that restricted community-contributed rules from being used in commercial products.

Key Differences from Semgrep:

• Fully open-source rules (no license restrictions)
• Community-driven governance
• No proprietary feature lock-in
• Compatible with Semgrep CE syntax and rules
• Focused on keeping critical features open
• Commercial integration friendly
