Your website breaks at 2am. Sentinel fixes it before you wake up.
An AI watchdog that scans your website or app every 30 minutes, catches bugs and crashes, explains them in plain English, and automatically fixes the safe ones — then emails you it's resolved.
Free 30-day trial · no credit card to start · installs on any site in minutes
You can't watch your site 24/7. Sentinel can.
Most businesses only find out their site is down when a customer complains — or worse, when the sales just stop.
Outages happen off-hours
Nights, weekends, holidays — exactly when no one's looking at the dashboard.
The alerts are gibberish
Most tools throw a stack trace at you. You're a business owner, not a server engineer.
Every minute down = lost money
Broken checkout, blank pages, expired SSL warnings scaring buyers away.
How Sentinel works
Five steps, running quietly in the background, every 30 minutes.

Questions, answered
The things people ask before they install Sentinel.
What does Sentinel monitor?
Uptime and crashes (4xx, 5xx), missing or broken page content, error messages on the live page, slow response, SSL expiry, and — on WordPress — outdated plugins, core and themes. Every 30 minutes.
Does it really fix problems automatically?
Yes, for safe issues — clearing cache, restarting a service, rolling back a bad change. Risky fixes are proposed for your one-click approval, and anything touching data or security is alert-only.
What kind of website or app can use it?
Any of them — WordPress, Shopify, custom apps, APIs. If it has a web address, Sentinel can watch it.
How much does it cost?
The agent and a 30-day trial are free. Plans start at R149 per site per month, and R599 for full AI auto-healing.
