Cronitor vs IsDown Pricing (2026)

Which one is cheaper?

One or both use custom pricing, so it depends on your specific needs.

Can I use either one for free?

Cronitor has a free plan. IsDown doesn't — though they do offer a free trial.

How do they charge?

Different approach here. Cronitor uses usage-based pricing, while IsDown goes with hybrid. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. Cronitor: They're threading the needle between cheap open-source alternatives and pricier observability platforms like Datadog or Checkly. The $2/monitor entry point is approachable, but a mid-sized team with 50 monitors and 5 users is already at $125/mo — not dirt cheap, but still well below enterprise APM pricing. IsDown: At $49-$179/mo before enterprise, IsDown sits mid-market — pricier than bare-bones uptime checkers but nowhere near what enterprise incident management platforms charge. They're clearly chasing growing teams and agencies who've outgrown a free monitor tool but don't need a full incident command center yet.
