Is Mockbin by Zuplo (mockbin.io) down?

UP right now — answered HTTP 200 in 42 ms.

Last checked 2026-09-11T20:30:45Z · checked every hour · OK-rate 24h: 100% · 7d: 100% · raw JSON · Atom feed of its down/recovered events

Context: The free successor: single fixed-response bins + request log. Bins are immutable and undeletable, and anyone holding the bin URL can read the full request log — including callers' IP addresses.

What we check: GET https://mockbin.io/ — a plain, keyless request from Cloudflare's network with an honest bot UA, exactly what a tutorial curl or an <img> tag experiences. OK = HTTP 2xx/3xx within 8s. No retries, no cookies, no API keys.

Need a request bin that's still alive?

If mockbin.io is failing (or you're tired of finding out mid-demo), Mockbird gives you a request bin whose URL never expires — method, headers (webhook signatures included) and body captured in an inspector, with control over the response — free, no signup:

curl -X POST "https://mockbird.mockbird.workers.dev/m/demo/hooks/anything" \
  -H 'content-type: application/json' -d '{"hello":"bin"}'
# see it captured (public demo inspector):
curl "https://mockbird.mockbird.workers.dev/api/projects/demo/requests"

README badge

Does your project's test suite or tutorial depend on mockbin.io? Embed a live status badge — it re-renders from our latest check (cached 5 min):

<!-- Markdown -->
[![mockbin.io status](https://mockbird.mockbird.workers.dev/status/mockbin-io/badge.svg)](https://mockbird.mockbird.workers.dev/status/mockbin-io)

<!-- HTML -->
<a href="https://mockbird.mockbird.workers.dev/status/mockbin-io"><img src="https://mockbird.mockbird.workers.dev/status/mockbin-io/badge.svg" alt="mockbin.io status"></a>

Green = answering plain GETs, red = network-dead, amber = answering but with an error status. Every tracked service has one; there's also a summary badge for all 71.

Get pinged when it goes down

Subscribe any webhook URL — no account needed. One message when mockbin.io goes down, one when it recovers (debounced: two consecutive hourly checks must agree, so a single blip never fires). Slack and Discord incoming-webhook URLs get a formatted message; anything else gets an HMAC-signed JSON POST.

Or from a terminal / CI script:

curl -X POST https://mockbird.mockbird.workers.dev/api/status/watch \
  -H "content-type: application/json" \
  -d '{"service": "mockbin-io", "url": "https://hooks.slack.com/services/T000/B000/XXXX"}'

Use "service": "*" to watch all 71 tracked services at once. The response includes an unsubscribe curl; 5 consecutive failed deliveries auto-unsubscribe. No webhook? Omit "url" to get a pollable subscription instead — GET the returned poll URL anytime for the transitions since your last poll. Full API details →

The same checker can watch your own URL: POST /api/status/monitor {"url": "https://api.example.com/health", "notify": "<webhook>"} — every 30 minutes, alert on down + recovery, free, no account. Monitor API →
