Outage Owl monitors vendor status pages and alerts your team via Slack when issues arise before customers start complaining.
The twist: it also shows your customers an automatic banner when vendors go down, so they know it's not your fault.
How it works: 1. Pick vendors to monitor (OpenAI, Cloudflare, GitHub, Twilio, Vercel, and 15+ more) 2. Connect Slack to get instant alerts 3. Add a one-line script to your site for automatic customer banners
Key features: - Real-time monitoring of 20+ vendor status pages (checked every minute) - Slack alerts with configurable delays and quiet hours - Customer-facing widget that auto-shows during outages - Custom incident announcements - No vendor lock-in for customer notificationsโworks on any website
Free tier available โ 1 alert rule, any vendor.
Built for SaaS teams who are tired of finding out about outages from angry support tickets.
