Works With Any Tunnel
Use your existing setup. LPI adds the visibility layer.
Quick Start
Pay Once. Use Forever. No Subscriptions.
This is a true lifetime deal. One payment, permanent license. Not “lifetime of the service” - you own the software forever.
- Yours forever - no renewals
- All v1.x updates included
- Unlimited installs & requests
3 months of ngrok = $30. Own LPI forever for less.
Not a VC-backed startup. An indie developer who ships.
I'm Alan Fuller. I've been building open source software for over a decade. My WordPress plugins run on 70,000+ websites. When you buy LPI, you're supporting an independent developer who actually maintains their software.
As someone who mucks around in the world where WordPress plugins meet the webhook interactions of the wider Web, this is a great addition to the toolset, and you've got to love how lightweight it is.
Quick Answers
What's the catch with the free trial?
No catch. Full access for 14 days. Just download and run. No signup, no credit card, no email required. If you like it, buy a license. If not, no hard feelings.
How is this different from ngrok?
ngrok is a tunnel service ($10/month). LPI is a debugging tool that works WITH any tunnel. You see every request detail, replay failed webhooks, and keep all data on your machine.
Does it work with [my webhook provider]?
Yes. Stripe, GitHub, Shopify, PayPal, Twilio. If it sends HTTP requests, LPI captures it. It's a transparent proxy.
What happens after the trial?
The trial simply stops working. Your data stays on your machine. Buy a $29 license to keep using it.
