Transparent HTTP proxy for local development. See every webhook request/response, mock failures, search history. When your backend crashes, LPI keeps responding. Single binary, works offline, SQLite storage. Built by devs who hate losing webhook data.

After building payment integrations for multiple projects, I noticed I was solving the same webhook debugging problems over and over. So I built LPI - a transparent HTTP proxy specifically for my local development. Key differentiator: When your backend crashes (and it will), LPI keeps responding with mock data so webhooks don't fail. You can configure response codes, delays, and body content. The webhook sender stays happy, you keep debugging. Everything runs locally - no sending sensitive payment data to cloud services. SQLite for storage, embedded web UI, single binary distribution. Currently tested with Stripe, PayPal, Gumroad, GitHub, and various custom webhooks. Binary sizes: ~11MB for all platforms. Zero runtime dependencies. Written in Go for the proxy, Vue.js for the UI. What features would convince you to switch from your current debugging tool? I'm especially interested in what people are using for webhook replay functionality.

I'm not a dev but work with devs and this makes absolute sense.

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. Because if a webhook call isn't working, it's extremely handy to just replay the incoming call till you figure it out.
