Your app texts you
before users do.
CanaryHub watches your web apps and API backends — including the API behind your iOS app — and messages you the instant something breaks. Downtime, latency spikes, and daily digests, delivered straight to Telegram, SMS, email, Slack, or Discord. Reply /status any time.

Live feed
Checked every 60 seconds, around the clock.
Every monitor gets hit on a schedule — status codes, response times, and recoveries confirmed. When a check fails, the alert is already on your phone before you could have refreshed a dashboard.
Observability, minus the app.
Most monitoring tools hand you one more dashboard to check. CanaryHub sends everything worth knowing to the chat apps already on your phone — and answers when you ask. There's an iOS app on the way, but the whole point is that you'll never need it to stay covered.
Setup
Live in three steps. Under five minutes.
- 01
Connect your app
Point CanaryHub at a URL, or plug it securely into your Fly.io, Heroku, or self-hosted deployment. Add a /health endpoint and we read the standard contract automatically.
- 02
Choose your channels
Connect Telegram in one tap and alerts land on your phone. Set how often we check, from every 5 minutes down to every 60 seconds.
- 03
Get alerted
We watch for downtime, latency spikes, and failovers around the clock. The moment something breaks, your phone buzzes — and again when it recovers.
Signals
Everything a watch loop should catch.
Downtime alerts
We hit your endpoints on a schedule and tell you the second they stop answering — then again the moment they recover.
Latency spike detection
Set a threshold and we'll catch the slow creep before your users do. Response times tracked on every check.
Failover detection
Know when traffic shifts regions or instances restart. CanaryHub sees the handoff and confirms the recovery.

FAQ
Questions, answered.
How does CanaryHub connect to my app?
Point it at a public URL for a plain up-check, or add a /health endpoint and we read the standard contract — status, version, and per-dependency checks. For Fly.io and Heroku, secure integrations give us deeper signal without you installing an agent.
Is it secure?
CanaryHub only needs to reach your health and status endpoints — it never touches your data or runs code inside your app. Integration credentials are scoped to read-only health signals and stored encrypted.
Which channels can alerts go to?
Telegram, SMS (US numbers), email, Slack, and Discord — all on every plan. Text /status to your CanaryHub number any time for an account summary.
Can I monitor the API behind my iOS app?
Yes — that's a core use case. Your app's reviews depend on its backend staying up, so CanaryHub watches that API exactly like any other web service and alerts you the moment it degrades.
What counts as a monitor?
One monitor is one thing we watch on a schedule — a website, an API, or a single backend service. Free covers 3 monitors in one project, Pro covers 3 projects with unlimited monitors each, and Business is unlimited.
