Website Monitoring for SaaS Founders
You're building a product, not managing monitoring infrastructure. Oh Dear gives you the checks that matter, uptime, cron jobs, SSL, status pages, without the complexity of enterprise tools.
Ship with confidence. Sleep through the night. Know when something breaks before your customers do.

Uptime monitoring that just works
Your SaaS is your business. When it goes down, you need to know immediately, not when a customer tweets about it. We check every minute from multiple locations and alert you the moment something breaks.
No agents to install, no complex setup. Add your URL and you're done.
Background job monitoring
SaaS apps run on background jobs. Email queues, subscription billing, data syncs, report generation. When these stop running, problems compound fast.
We monitor your scheduled tasks and alert you when they fail or take too long. No more "why didn't that email go out?" debugging sessions.
Status pages build trust
A status page says "we take reliability seriously." When issues happen, it gives customers a place to check without flooding your support inbox.
Our status pages run on separate infrastructure, so they stay up even when your app doesn't. One less thing to worry about.
SSL certificates handled
Let's Encrypt makes SSL free, but it doesn't make renewal foolproof. We monitor your certificates and alert you before they expire, so you never wake up to a browser warning screen.
We also catch chain issues and misconfigurations that cause problems on specific browsers.
Performance tracking
Your app feeling slow? We track response times and alert you when performance degrades. Catch that database query gone wrong or that third-party API slowing things down.
Set performance budgets and get notified when you exceed them. Great for staying on top of technical debt.
API endpoint validation
A 200 status doesn't mean your API is working correctly. We can validate response content and check that endpoints return expected data. When your auth endpoint returns an empty response, you'll know.
Monitor the endpoints your customers depend on, not just your marketing site.
