Reliable infrastructure to work with webhooks and external events — without managing it yourself.
Two products: Event Gateway for Receiving Webhooks: Handle events from external providers before they hit your app — with full observability and control. And Outpost for Sending Webhooks: Deliver events to users' preferred systems reliably and securely — managed or self-hosted.

Request bins have been around for ages, but were built for humans. We thought it time to build something agent-native.
Inspect is a webhook tester you can use with your agent. No skills, MCP, or server setup required.
Get a URL and see requests arrive live, with payloads exactly as sent. Or paste the URL into Claude or Codex and it’ll tell you when a request lands, and use it to build your handler.
What's included:
Mock webhooks from 500+ providers, including Stripe, Shopify and GitHub
A live request feed that you and your agent can use
A path to production: forward to localhost with CLI, then move to Event Gateway for queues, retries and transforms.

Inspect is free to use, no account needed. Check it out and let us know what you think.
Nice idea making a request bin that the agent can read too. Do the mock webhooks from the 500+ providers include valid signatures, so I can test signature verification in my handler, or just the payload shape?
@galdayan We can handle the provider verification and handshakes, but it's just payload shape.
This is smart, and I love to see something not entirely dripping in AI for once
@lukeocodes Thanks Luke!
@lukeocodes Thanks, fella! 🫶
Hookdeck is pretty awesome. TBH webhooks have always been a thorn in our sides, so any attempts to make the problem suck less is greatly appreciated!
@thecodedrift Thanks Jakob! I hope it helps
The bit that stands out to me is the path to production — most test bins are a dead end, but here you can forward to localhost with the CLI and then graduate the same flow to Event Gateway for queues and retries. Also like that you can paste the URL into Claude or Codex and have the agent tell you when a request actually lands, instead of me babysitting a refresh button.
Every DM in StorkPlus reaches our agents as a Meta webhook, and the slow part is messaging our own test page just to see one payload again. Does the mock list cover WhatsApp, Messenger and Instagram events? And can an Inspect URL answer Meta's hub.challenge verification, so I can point a real test app at it too?
@ahmed_khaled32 WhatsApp is covered (I'll get the others added) and yes, we can handle the verification and handshakes for you
a live url i can hand to an agent without setting up a server is handy
the provider examples should also save that awkward step of waiting for a real event just to check the payload shape
@saad_el_gueddari Thanks Saad, I think you're right - rather than sitting waiting on a webhook response or refreshing the page, you can now hand that off to an agent.
