The short version

  • Each has a real cost: Checkmk pricing calculated by service count, not hosts (approximately 30 services per host on average); Dagger dagger is not a CI provider, so you keep paying for GitHub Actions or GitLab runners underneath it; the Dagger Cloud subscription is an addition to your CI bill, not a replacement for it.

What people use each for

The jobs each tool is most often brought in to do.

Checkmk

  • Infrastructure monitoringnot Dagger
  • System observabilitynot Dagger
  • Enterprise compliance monitoringnot Dagger

Dagger

  • A platform team maintaining near-identical build YAML across forty repositories that wants one versioned module every repository calls insteadnot Checkmk
  • An engineering organisation migrating off a CI provider that does not want to rewrite every pipeline as part of the migrationnot Checkmk
  • A team whose engineers waste hours pushing commits to debug CI-only failures and needs to reproduce the exact run locallynot Checkmk
  • A monorepo where most commits touch a small subset of services and cache-accurate step skipping cuts build minutes materiallynot Checkmk

Where each one falls short

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

Checkmk

  • Pricing calculated by service count, not hosts (approximately 30 services per host on average)
  • Professional support limited to 8-10 hours per week on base plans
  • Synthetic monitoring is separate add-on with per-test pricing

Dagger

  • Dagger is not a CI provider, so you keep paying for GitHub Actions or GitLab runners underneath it; the Dagger Cloud subscription is an addition to your CI bill, not a replacement for it.
  • Writing pipelines in Go or TypeScript raises the barrier to entry: a release engineer who could edit a YAML step now needs to read code, and the people who can fix a broken build shrink to those comfortable with the SDK.
  • The engine runs as a container on the runner and needs a persistent cache volume to deliver its main benefit, so ephemeral CI runners give you correctness without the speed, and provisioning durable cache storage is extra platform work.
  • The Team plan caps at ten users and ten million events per month; an organisation of any size crosses that quickly and moves to Enterprise pricing that is not published, so cost at scale is unknowable up front.
  • The module ecosystem is young and thinly maintained relative to the marketplace of a mature CI provider, so integrations that exist as a one-line Action often have to be written yourself as a Dagger function.

Answered from the vendors’ own pages

Checkmk: Is there a free version of Checkmk?

Yes, Checkmk Community edition is free forever and supports up to approximately 100 hosts for basic infrastructure monitoring with no cost.

Source
Dagger: Does Dagger replace GitHub Actions?

No. Dagger runs inside GitHub Actions or any other CI. It replaces the YAML that describes your pipeline steps, not the trigger and runner layer.

Checkmk: How does Checkmk calculate pricing by host count?

Checkmk uses service-based pricing where each monitored aspect (file system, hardware sensor, switch port, metric) counts as one service. On average, there are approximately 30 services per host.

Source
Dagger: Is the engine open source?

Yes, the Dagger engine and SDKs are open source and free. Dagger Cloud, the observability product, is what costs money.

Checkmk: What is the difference between Checkmk Pro and Ultimate tiers?

Pro tier at 190 EUR/month includes advanced analytics and 8x5 support, while Ultimate at 275 EUR/month adds full-stack observability, advanced compliance features, and upgradable 24/7 support.

Source
Dagger: What is an event in the pricing?

Dagger Cloud meters pipeline telemetry events. One million per month is free; the Team plan at 50 USD per month allows ten million.

Checkmk: Does Checkmk offer a managed SaaS option?

Yes, Checkmk CloudAI is a fully managed SaaS tier at 240 EUR/month with 99.5% uptime SLA and support for up to 50000 services.

Source
Dagger: Can I run the same pipeline on my laptop?

Yes, that is the main reason teams adopt it. The dagger CLI executes the identical graph locally, so CI-only failures become reproducible.
