Keep every SaaS product live, secure, scalable and profitable
SaaS Sentinel brings together operational monitoring, security and compliance oversight, cost analysis and capacity planning in one platform.

Built for apps made with Lovable and Supabase.

The SaaS Portfolio Intelligence Platform
The four pillars of SPI
SaaS Portfolio Intelligence (SPI) means managing your apps as one portfolio, not a collection of separate dashboards. SaaS Sentinel covers all four pillars.
What is SaaS Portfolio Intelligence?
Operational performance
Uptime, response times, database health, error logs and publishes for every app.
Learn moreSecurity and compliance
Security advisories, vulnerable packages, findings and a risk register with an audit trail.
Learn moreCost and profitability
Running costs per app, cost per licence, break-even and margin per customer.
Learn moreCapacity and growth
Weekly capacity reviews that tell you when a project needs to scale, and what it would cost.
Learn moreOperational performance · Made for Lovable
Never ship a Lovable app that still looks like a template
Every day SaaS Sentinel reads each app's home page and sharing tags, and tells you the moment a default Lovable title, preview image or favicon slips through.
- Last publish date for every app, with stale-publish warnings
- Each publish shown as a release event on your health charts — add version numbers
- Page title, description, sharing image, favicon, sitemap and robots checks
- Build and credit spend counted in your running costs
Operational performance · Supabase
See trouble in your database before your customers do

- CPU, memory, disk and connections with warning and critical limits
- Error logs gathered from every Supabase source, grouped and searchable
