Checkly Alternatives: NorthDuty vs Checkly

What Checkly's run quotas mean in practice

Checkly prices browser checks by monthly check runs: 1,000 on the free Hobby plan, 3,000 on Starter ($24/month) and 12,000 on Team ($64/month). A 30-day month has 43,200 minutes, so one browser check running every 15 minutes uses about 2,900 runs, and one running every 5 minutes uses about 8,600.

In other words, Starter covers roughly one browser check every 15 minutes, and Team covers about four checks every 15 minutes or one every 3–4 minutes. Running a check from more than one location uses the quota faster. That model suits engineering teams with a few critical Playwright tests; it gets expensive when you want checkout and forms checked frequently across many client sites.

NorthDuty counts journeys instead of runs: Starter ($29/month) checks 6 journeys every 15 minutes and Pro ($79/month) checks 15 journeys every 15 minutes, with no run quota and no Playwright code to maintain.

Why some teams look for a Checkly alternative

Checkly is often considered by teams that want browser and API checks in a code-oriented workflow. That can be a strong fit for engineering-led monitoring programs.

But not every buyer wants monitoring to live primarily inside an engineering workflow. Some teams want a faster path to business-facing website visibility, especially for broken pages, missing UI, checkout issues, and other customer-facing failures.

Why website health monitoring matters in this comparison

Many organizations need a platform that makes website reliability easy to understand across operations, product, marketing, ecommerce, and leadership teams. That means clear insight into whether important pages and journeys work, not only whether a scripted check passed.

NorthDuty is built around that goal. Every project combines website health checks every 5 minutes by default (uptime, SSL, DNS, blank-page detection, broken resources, JavaScript errors, and API call tracking in a single check) with AI-suggested or plain-text user journeys that keep a screenshot of every step.
