How to use Oh Dear coupon codes

  1. Pick an offer above and hit Get Code — the code appears and Oh Dear opens in a new tab.
  2. Add what you want to your cart, then find the promo code or discount box at checkout.
  3. Paste the code and apply it. Check the total drops before you place the order.

Savings tips for Oh Dear

  • Start with the biggest saving first — the top Oh Dear offer on this page is worth 50%. If checkout rejects it, work down the list; a smaller code that applies beats a bigger one that doesn't.
  • Of the 15 offers listed here, 5 need a code pasted at checkout and 10 are applied automatically when you click through. Copy the code before you leave this page — the discount box is easy to miss once you're in the cart.
  • Check the order total before you pay, not after. Most Oh Dear codes carry conditions — a minimum spend, selected products only, or new customers only — and checkout won't always say which one blocked it.

Oh Dear Website Monitoring: Uptime, SSL, and Cron Tracking

Oh Dear delivers comprehensive website health monitoring with uptime checks every minute, SSL certificate warnings, and performance tracking. Detect broken links and failed cron jobs before your visitors do.

A Monitoring Tool Built by Developers and Ops

Oh Dear launched in 2018 with two founders who brought complementary expertise to website monitoring. Freek Van der Herten, an agency owner and prolific open-source developer, represents the developer perspective—focused on what visitors see, including every feature, link, and page. Mattias Geniar, a systems administrator with fifteen years in infrastructure and security, brings the operations perspective—thinking about what breaks a site at the infrastructure level: servers, certificates, DNS, and other non-code factors. Their founding insight was that comprehensive site monitoring requires both viewpoints. A typical monitoring tool focuses on either uptime or performance from one angle, missing critical parts of the picture. Oh Dear was built to combine both the developer's and operator's views, creating a tool that covers your entire site health. This dual-perspective approach shaped the product's development from day one.

What Oh Dear Monitors Across Your Website

Oh Dear offers a comprehensive monitoring suite built around several core capabilities. Uptime monitoring runs every minute from multiple locations, so you know instantly when your site goes offline. SSL certificate monitoring watches your certificates and alerts you well in advance of expiration, preventing the embarrassment of a padlock disappearing from browsers. Broken link detection crawls every page of your site to flag links leading nowhere. Mixed content detection catches assets loading over insecure HTTP connections that could break your padlock. Scheduled task monitoring tracks cron jobs, alerting you when they run late, fail, or stop running entirely. Performance monitoring measures page load speeds to catch slowdowns before they impact user experience. Finally, Oh Dear provides hosted status pages that keep your users informed when issues occur, so they don't have to guess what's happening.

Pricing: Starting Free, With Discounted Plans

Oh Dear makes it easy to get started with monitoring through a free 10-day trial that requires no credit card. This trial period gives you full access to all monitoring features, allowing you to test uptime tracking, certificate alerts, link crawling, and performance monitoring without payment. For ongoing monitoring after the trial, Oh Dear operates on a subscription model with plans designed for different team sizes and monitoring needs. While specific pricing isn't advertised on the homepage, several discount codes and promotional offers are available to help reduce subscription costs. These include percentage-off promotions on both standard and premium plan tiers. Whether you're a solo developer, small agency, or larger team, Oh Dear's structure allows you to pay for what you actually monitor, scaling your subscription as your site monitoring needs grow.

Who Should Choose Oh Dear for Site Monitoring

Oh Dear is ideal for any team responsible for maintaining website health—whether that's a developer, agency, or operations team. If you're running a production website, the uptime monitoring alone pays for itself by catching outages before customers report them. Developers will appreciate the broken link detection and mixed content checking, which catch issues that affect user experience. If you maintain any automated tasks, cron job monitoring prevents failed background jobs from silently breaking your site's functionality. For agencies managing multiple client sites, Oh Dear's multi-location uptime checks ensure you're monitoring from perspectives that matter to your actual users. The included status page feature is valuable if you have a user base that needs transparency during incidents. Start with the free 10-day trial to evaluate whether the combination of developer-focused and operations-focused monitoring features meets your needs. Look for current discount codes to reduce the cost of ongoing monitoring once you decide to continue beyond the trial period.
