Zero False Positives

Every finding is verified against real execution — not pattern matching. If Paragon flags it, it's a real issue.

Paragon sandboxed review environment

Reviews grounded in execution.

Most review tools scan diffs for patterns. Paragon clones your repo, installs dependencies, compiles the project, and runs your test suite. Every comment is backed by real execution — not guesswork.
