One-click observability
for your apps.
CanaryHub watches your web apps and API backends — including the API behind your iOS app — and texts you the instant something breaks. Plugs securely into Fly.io, Heroku, and self-hosted apps. Alerts on downtime, latency spikes, and failovers, delivered to Telegram, WhatsApp, and SMS.

[ 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
Pick where alerts land: Telegram, WhatsApp, SMS — or all three. Set how often we check, from every 5 minutes down to every 30 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.
Telegram · WhatsApp · SMS
Alerts go straight to your phone on the channels you already check. No dashboards to babysit.
Fly · Heroku · self-hosted
Plugs in securely wherever you run. No agents to install on plain up-checks; deeper hooks for Fly and Heroku.
Watch your iOS app's backend
Your app store rating lives and dies by the API behind it. CanaryHub monitors that backend like any other service.

[ 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 on every plan, plus WhatsApp and SMS on Pro and Business. Choose one or route to all of them, so an outage reaches you wherever you are.
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 1, Pro up to 4, and Business is unlimited.
