api.example.comUptime during sales and promotions
Black Friday traffic spike. Flash sale launch. The worst time for your store to go down. We check every minute from multiple global locations so you know instantly when something breaks.
Get alerted before customers start tweeting about it, and have time to fix it before you lose the sale.
Page speed impacts conversions
Amazon found that every 100ms of latency costs 1% in sales. We track response times across your store and alert you when performance degrades, so you can fix it before conversion rates drop.
Set performance budgets for critical pages like product listings, cart, and checkout. Get notified when they're exceeded.
Checkout endpoint monitoring
A 200 status code doesn't mean checkout is working. We can validate response content and check that critical endpoints return expected data. When your payment integration silently fails, you'll know.
Monitor APIs, webhooks, and integrations that your store depends on, not just the homepage.
SSL certificates build trust
That padlock icon matters. Customers won't enter payment details on a site with certificate warnings. We monitor SSL health and alert you 30, 14, and 7 days before expiration.
We also catch chain issues and misconfigurations that cause intermittent HTTPS failures on some browsers.
Background job monitoring
E-commerce runs on background jobs. Inventory syncs, order confirmations, shipping updates, abandoned cart emails. When these stop running, problems compound quickly.
We monitor scheduled tasks and alert you when they stop running or take too long. No more silent failures.
Broken links lose sales
A broken product link from Google, an affiliate, or an email campaign is a lost sale. We crawl your store daily and flag dead links before they cost you customers.
Especially valuable after catalog updates, CMS changes, or platform migrations.

Alerts to the right team
Downtime alerts go to your ops team. SSL issues go to your developer. Broken links go to your content manager. Use Slack, PagerDuty, email, or webhooks to match your workflow.
When something breaks at 3am during a sale, the right person gets paged.
Status pages for customers
When your store has issues, customers want to know what's happening. A status page reduces support tickets and shows you're on top of it.
Our status pages run on separate infrastructure, so they stay up even when your store doesn't.
Frequently asked questions
Oh Dear checks your store every minute from multiple global locations. The moment we detect downtime, you'll receive an alert via your preferred channel (Slack, email, SMS, PagerDuty, etc.). Most customers receive alerts within 60-90 seconds of an outage starting.
Yes. Oh Dear can monitor any URL including checkout endpoints, cart pages, and API endpoints. We can also validate response content to ensure critical endpoints return expected data - a 200 status code doesn't always mean checkout is working correctly.
Amazon found that every 100ms of latency costs 1% in sales. Slow pages lead to abandoned carts and lost conversions. Oh Dear tracks response times and alerts you when performance degrades, so you can fix issues before they impact your bottom line.
Absolutely. We alert you 30, 14, and 7 days before your SSL certificate expires. We also detect chain issues and misconfigurations that cause intermittent HTTPS failures - problems that can scare customers away from entering payment details.
Yes. E-commerce runs on background jobs - inventory syncs, order confirmations, shipping updates, abandoned cart emails. Oh Dear monitors scheduled tasks and alerts you when they stop running or take too long. No more silent failures compounding into bigger problems.
