Why Choose LPI?
Built for Developers, by a Developer
I built LPI to give developers complete visibility into webhook integrations. Debug production issues, understand failures, and ship fixes with confidence - all without cloud dependencies or usage limits.
Your Data Stays Yours
With LPI, all your HTTP traffic is stored locally in SQLite. No cloud uploads, no data retention policies, no privacy concerns. Export your data anytime, keep it forever.
Debug Anywhere, Anytime
Never lose debugging capability. Works offline, in restricted environments, on any platform. Debug production issues even when external services are down.
Unlimited Debugging Power
Debug as many webhooks as you need. Run multiple projects simultaneously. Keep full request history. Your debugging capability scales with your needs, not your budget.
Build Integrations Before Your Backend
Start webhook development immediately with mock mode. Test edge cases, error handling, and integration flows without waiting for backend APIs. Ship reliable integrations faster.
30-day money-back guarantee. No questions asked.
