Checkly review

Checkly is managed synthetic monitoring for APIs and web applications. It runs scheduled checks to catch availability, correctness, and performance problems, then alerts teams when a service is down or a user flow breaks. That puts it beyond a basic uptime ping: checks can validate API status codes, headers, response payloads, and latency, or run Playwright browser flows across Chromium, Firefox, and WebKit.

Teams can define monitors as TypeScript or JavaScript and deploy them with the Checkly CLI. The product also covers cron jobs and background workers with heartbeat monitors, plus customizable public or private status pages. It can correlate failures with OpenTelemetry traces and generate AI root-cause analyses. The core platform is managed SaaS, not a self-hosted Checkly instance. In one Reddit thread, a user looking for self-hosted options said Uptime Kuma handled only basic tests and wanted more involved Playwright monitoring with history.

Checkly’s main advantage is the range of checks in one monitoring product. Teams can use API checks for endpoint behavior and browser checks for complete user flows, rather than treating a passing HTTP response as proof that an application works. Browser checks use Playwright and support Chromium, Firefox, and WebKit.

Monitoring as code is useful for teams that want checks versioned and deployed alongside application code. The CLI accepts TypeScript or JavaScript monitor definitions. Heartbeat monitors extend coverage to cron jobs and background workers, while status pages and alerting policies cover incident communication. The platform also supports private monitoring locations and can connect failures to OpenTelemetry traces; AI root-cause analysis is available with plan-specific limits.

The listed entry point is a free Hobby plan, and paid plans start at $29 per month or $24 per month billed annually. Hobby includes 10,000 API runs and 1,000 browser runs monthly. For a small team evaluating browser and API coverage together, those allowances provide a no-cost way to start, though the free plan has other tight caps.

The limits matter more than the headline price. Hobby is capped at one user, 10 uptime monitors, 10,000 API runs and 1,000 browser runs per month, with no overages permitted. It also allows only six public locations, up to three per check, and retains raw data for seven days. The 14-day free trial does not change those ongoing plan limits.

Starter costs $29 monthly or $24 per month billed annually, but includes only three users, 50 uptime monitors, 25,000 API runs and 3,000 browser runs. Exceeding the run allowances costs $2.60 per 10,000 API runs and $6.50 per 1,000 browser runs. Team rises to $80 monthly or $64 annually; it includes 10 users, 75 monitors, 100,000 API runs and 12,000 browser runs. Its overages are still metered.

Enterprise pricing is not published. Private locations are included on Team and Enterprise, not listed for Starter or Hobby. Teams looking for self-hosting should also note that Checkly’s core platform is managed SaaS.

Checkly has a free Hobby plan, then paid plans start at $29 per month, or $24 per month billed annually, according to the published pricing details. Hobby includes one user, 10 uptime monitors, 10,000 API runs and 1,000 browser runs per month. Its run limits are firm: Hobby overages are not permitted.

Starter costs $29 monthly or $24 per month annually. Moving to Team is a sizeable jump: $80 monthly or $64 per month annually. Team raises the limits to 100,000 API runs and 12,000 browser runs, adds private locations, and includes 10 users. Starter has 25,000 API and 3,000 browser runs, and three users.

Price the overages before choosing: Starter charges $2.60 per extra 10,000 API runs and $6.50 per 1,000 browser runs. Team charges $2.50 and $6.25, respectively. Extra uptime monitors cost $8 per block of 25, or $10 per month on monthly billing. Communicate and Resolve add-ons have separate annual-billing prices. Enterprise pricing is not published; the listed limits and overages require custom terms.

Checkly’s monitoring-as-code approach lets teams define and deploy monitors as TypeScript or JavaScript with its CLI, and browser checks use Playwright. Teams already maintaining Playwright flows or code-based monitoring may have a more direct path than teams rebuilding checks from another system. The exact migration work depends on how much check logic, alerting and status-page setup needs to be recreated; migration tooling is not specified on the vendor's site.

Checkly is managed SaaS, and the product details say it is not for teams that require self-hosting. That can be a deciding factor when moving off the service. Data export options are not published on the vendor's site, so confirm what can be exported before committing, especially because data retention varies by plan.

We were not given Reddit posts or comments about Checkly, so we can’t substantiate reasons users leave or attribute a switching complaint to Reddit. The pricing details do identify one practical risk: high-volume teams can incur run overages, while Hobby users cannot buy overages.
