Hey Product Hunt community! 👋 I'm Gaurav, creator of FlowPrecheck. As n8n has grown into the primary automation engine for thousands of agencies, freelancers, and engineering teams, a recurring problem kept coming up: when a workflow grows to 30+ nodes, a single unhandled 502 or missing retry policy can silently halt business operations at 3 AM. Traditional QA practices (unit tests, static analysis, linter checks) exist for code, but low-code workflows were usually tested by trial-and-error in production. That’s why we built **FlowPrecheck**: 🔍 **Pre-Flight Static Analyzer**: Drop any n8n workflow JSON to scan 30+ structural risk vectors — unhandled HTTP exceptions, missing retry policies, circular loops, and credential candidates. 📊 Production Readiness Score: Receive a clear 0–100 score (Ready, Review Needed, Risky) with step-by-step remediation advice for each node. 🛡️ Credential Privacy First: We never ask for your n8n credentials or API secrets. All scanning is performed strictly on structural node JSON. ⚡ CI/CD & Integration Ready: Sync directly with your n8n instance or GitHub repositories to enforce pre-flight checks before every client handoff. You can try it live right now without creating an account: https://flowprecheck.vercel.app/ I’d love to hear your thoughts, feedback, or any n8n horror stories you've experienced in production!
