PlaybookLint

PlaybookLint is a web app (with optional CLI) that automatically tests, validates, and “lint-checks” SOAR playbooks before deployment. Most SOAR failures aren’t fancy—they’re brittle connectors, missing fields, bad assumptions about data formats, and unhandled error paths that only show up during an incident. This tool builds a sandboxed test harness that replays sanitized historical alerts and synthetic edge cases against your playbooks, then reports what breaks, where time is wasted, and which steps are non-deterministic. It generates a clear diff-style report, suggests safer defaults (timeouts, retries, idempotency guards), and produces compliance-friendly evidence that playbooks were tested. It integrates with common SOAR platforms via APIs and focuses on reducing incident-time surprises rather than promising “full autonomous response.” It’s not glamorous, but it’s the kind of reliability tooling teams actually keep paying for.
