Semgrep
By Semgrep
A fast, pattern-matching SAST engine popular for how easy its rule syntax is to write custom checks in. The CLI/engine itself is LGPL-2.1, but the default rule registry bundled with the free Community Edition moved to a separate, non-OSI Semgrep Rules License in December 2024 — a shift that prompted the community to fork a fully open alternative, Opengrep, in early 2025.
