Know which vendors will shut down

Death signals we track
A SaaS product rarely dies overnight. The signs are there, months in advance.
API Health Decay
Endpoints returning errors, response times climbing, SSL certs expiring. We ping continuously and track degradation over time.
Domain & DNS Signals
Domain approaching expiration, DNS records changing, nameservers going dark. We catch it before the domain drops.
Product Trajectory
Wayback Machine snapshots, changelog frequency, social media silence, job postings disappearing. The patterns don't lie.
Team & Funding Signals
Employee departures, leadership changes, funding runway drying up. When the team shrinks, the product follows.
API Deprecation Detection
Tracking public sunset announcements, EOL notices, and changelog entries about deprecated endpoints. The clearest sign a vendor is winding down.
Outage & Incident Monitoring
We track real-time status page data, crowd-sourced outage signals, and historical incident records for every vendor — and feed it into the composite health score. When a vendor has a history of going dark, that shows up.
Real-Time Endpoint Monitoring
Point us at any public URL — API health endpoint, status page, login screen. We check reachability on your schedule (Pro: every 5 min, Team: every 1 min) and alert the moment it goes down or slows. Separate from vendor health score — uptime is uptime, not strategy.
The graveyard is growing
These products had paying customers when they died. Their users had no warning.
Your stack is only as reliable as your weakest vendor
SunsetRadar watches the vendors you depend on, tracks their Death Clock trajectory, and alerts you before a vendor goes dark — not after.
