• Custom rules are genuinely writable — you can encode your own security or architecture standards in an afternoon.
• Free CLI with a large community rule registry is immediately useful.
• Fast enough to run on every pull request without complaint.

• Licence compliance reporting is the strongest in the category and often the reason legal approves a release.
• Reachability analysis reduces the transitive-dependency alert flood.
• Automated remediation pull requests.

• Pattern matching without full dataflow misses some vulnerability classes.
• Community rule quality is uneven; expect to curate.
• Advanced dataflow and supply-chain features are paid only.

• SAST is weaker than dedicated code-analysis vendors.
• Enterprise pricing and sales process.
• Interface is dated in places.

Teams that want customisable static analysis and can start entirely for free.

Enterprises where open-source licence compliance is as important as vulnerability management.
