Testing webhooks means running ngrok — a tunnel that dies when your laptop sleeps, dropping events you can't recover. RelayFox captures every webhook server-side. Paste your URL into Stripe, GitHub, or Shopify. Watch requests arrive live. Run `npx relayfox` to forward them to localhost. Replay any past event on demand. Free: 24-hour URLs, live inspector, CLI forwarding, share links. Pro ($9/mo): permanent URLs, 30-day history, team collaborators.
