Despite the fact that there is an open source repository containing community rules, some Semgrep users prefer to keep their custom rules in repositories that they manage.
The goal of semgrep-rules-manager is to collect high-quality Semgrep rules from third-party sources. It allows you to examine information about a source, download it, and check for and retrieve remote updates. If a downloaded source no longer meets your requirements, semgrep-rules-manager can handle deletion procedures.
This online search engine allows you to explore the rules included in semgrep-rules-manager.
