hostc

Test webhooks on localhost

Stripe, GitHub and Slack can only call a public URL. hostc gives the server on your machine one, so webhooks reach the code you are editing.

How to do it

  1. Start your server, then point hostc at its port:

    npx hostc@latest 3000

  2. Add the printed URL plus your route to the provider, for example https://k7m2xq9pa4dn.hostc.app/webhooks/stripe.

  3. Trigger an event. Each request shows up in your terminal with its status and duration.

Good to know

  • Signature checks work: the body and headers such as Stripe-Signature reach your server as they were sent.
  • Every start of hostc gives a new URL, so update the provider when you restart it. After a network drop, the URL stays for up to 10 minutes.
  • hostc waits up to 2 minutes for your server, but providers often give up sooner and retry.
  • Anyone with the URL can call it, so verify signatures as you would in production.
