CurlFactory turns the URLs you fire all day into a grid of one-tap buttons. Pick an icon, paste an endpoint, and tap to send. No accounts, no servers, no friction. Built for makers, devs, and tinkerers who already have webhook URLs scattered across notes, group chats, and bookmark folders. CurlFactory gives them a home - your home screen. WHAT YOU CAN DO ⢠Save any HTTP or HTTPS endpoint as a labeled, color-coded tile ⢠Choose from 100+ icons covering home, work, travel, tools, money, media, and more ⢠Tap a tile to fire the request and get an instant toast with the status code and timing ⢠Inspect the response: tap a successful toast to see status, headers, and the first 4 KB of body ⢠Hide sensitive curls behind Face ID - tokens stay invisible to over-the-shoulder eyes ⢠Reorder, duplicate, or delete with a long-press ⢠Skip onboarding, jump straight to building PERFECT FOR ⢠Triggering Home Assistant, Hubitat, or Homebridge automations ⢠Firing IFTTT or Zapier webhooks from your home screen ⢠Pinging your own dev environments and APIs ⢠Smart-home appliances that expose a local URL ⢠Anything you'd otherwise paste into curl in a terminal ON-DEVICE PRIVACY CurlFactory was designed with privacy as the default. There is no account, no analytics, no telemetry. Every URL, title, and icon stays in your iPhone's app sandbox. Optional Face ID gating adds a second layer for sensitive endpoints. The app does not collect data - see our privacy policy for details. FREE & UNLIMITED ⢠5 saved curls free, forever - no trial, no clock ⢠Unlock unlimited curls with a one-time in-app purchase.
