Which is cheaper, Checkly or Galileo?

Checkly starts at Free and Galileo at Free.

Does Checkly or Galileo run on more platforms?

Checkly runs on Web, CLI, API. Galileo runs on web, api.

Can I use Checkly for free?

Both have a free tier, so you can try either at no cost before committing.

What is Checkly best used for?

Checkly is most often used for monitor api endpoints with custom assertions, test user journeys with browser automation, detect performance degradation across regions, verify dns and tcp connectivity. Of those, monitor api endpoints with custom assertions and test user journeys with browser automation are not what Galileo is typically brought in for.

What can Checkly do that Galileo cannot?

Checkly covers Uptime monitoring, Synthetic browser testing, API monitoring, Heartbeat monitoring. Galileo covers Pre-built evaluations, Ground truth capture, Luna models, Agent behavior analysis.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Checkly

Free tier has limited check allocations per month
Overage charges can add up with high-volume workloads
Status pages require separate paid tier
Root cause analysis is separate billing component

Galileo

The free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.
Real-time guardrails and unlimited trace capacity are reserved for the custom-priced Enterprise tier.
Pro plan pricing scales with trace volume, so costs can grow unpredictably as usage increases.
On-premises deployment requires an Enterprise contract rather than being available self-serve.
