What it is
Sentinel is an installable monitor that scans any website or app every 30 minutes for downtime, server errors, crashes, slow pages, SSL certificate expiry, and content and file integrity. For WordPress sites it also flags out-of-date core, plugins and themes. When it finds a problem it opens an incident, alerts the owner, and for safe issues it heals itself and emails a Resolved notice.
Sentinel does not just ping the home page. It checks every page of a site, discovered from the sitemap and permalinks, so a broken product page or a failing checkout is caught the same way an outage would be. The safe fixes it runs on its own include clearing caches, opcode cache and rewrite rules, then rechecking before it closes the incident.
It is a live build on imbilladigitalagency.com with preview pages staged, a downloadable WordPress plugin, and a Python agent already shipping. imbilladigitalagency.com and Launchpad are themselves being watched by it.
What it does
Checks every page on a 30-minute cycle for downtime and for server errors across the 4xx and 5xx range.
Flags crashes and slow pages so a degraded site is caught before customers feel it.
Tracks the certificate and warns ahead of expiry, so the padlock never lapses unnoticed.
Watches for unexpected changes to content and files, catching tampering or broken deploys.
Flags out-of-date core, plugins and themes so security gaps are surfaced early.
Reads each incident and explains what went wrong in plain English to speed up the fix.
Resolves safe issues automatically, asks for one-click approval on the next tier, and alerts only on the rest.
Routes incidents and resolutions to the owner over email, with Slack, WhatsApp and SMS built in.
How it works
Sentinel uses a hybrid architecture. A lightweight agent runs on the customer's own server. Any site can use the Python agent, while WordPress sites can install a one-click plugin instead. Only the error signal leaves the customer site, never their data. The central brain and the AI diagnosis run on Imbilla's side, so the customer carries almost no overhead.
Auto-fix is tiered and never blind. Tier 0 heals safe issues automatically, tier 1 needs one-click approval before anything changes, and tier 2 is alert-only. AI diagnosis currently uses Google's Gemini free tier.
- Lightweight agent on the customer server, with a Python agent for any site and a one-click plugin for WordPress.
- Only the error signal leaves the site, never customer data.
- Central brain and AI diagnosis run on Imbilla's side.
- Tiered auto-fix: tier 0 auto-heal, tier 1 one-click approval, tier 2 alert-only.
Who it is for
Business owners and agencies who cannot afford downtime, and who want a watchdog watching every page of their site around the clock rather than just the front door. Imbilla can also run Sentinel for its own clients as a managed service.
Commercial
Three tiers, billed per site per month, with a 30-day free trial.
Status and roadmap
Sentinel is a live build with preview pages staged, a customer status page, magic-link sign-in and retention email journeys. imbilladigitalagency.com and Launchpad are already being watched by it.
The roadmap runs in order:
- AI diagnosis of incidents. Done.
- Safe tier-0 auto-heal. Done.
- Multi-channel alerts and a full dashboard. Next.
- A multi-tenant SaaS with billing. After that.
