The short version

  • Only Dagger has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Microsoft Defender defender Suite requires existing Microsoft 365 E3 or equivalent base licensing
  • Prices and features above were last checked on 31 August 2026.

What people use each for

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

Dagger

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

  • SaaS application security monitoringnot Dagger

Where each one falls short

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

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.

Microsoft Defender

  • Defender Suite requires existing Microsoft 365 E3 or equivalent base licensing
  • Some Defender products use pay-as-you-go pricing with variable costs
  • Prices vary based on Microsoft agreements, requiring sales contact for custom quotes

Questions people ask

Is Dagger or Microsoft Defender better?
Neither clearly leads. Dagger starts at Free and Microsoft Defender at $12/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Dagger or Microsoft Defender?
Dagger has a free tier; the other does not. Paid plans start at Free for Dagger and $12/month for Microsoft Defender.
Does Dagger or Microsoft Defender run on more platforms?

Can I use Dagger for free?
Yes. Dagger has a free tier, so you can try it without paying. Microsoft Defender starts at $12/month.
What is Dagger best used for?
Dagger is most often used for a platform team maintaining near-identical build yaml across forty repositories that wants one versioned module every repository calls instead, an engineering organisation migrating off a ci provider that does not want to rewrite every pipeline as part of the migration, a team whose engineers waste hours pushing commits to debug ci-only failures and needs to reproduce the exact run locally, a monorepo where most commits touch a small subset of services and cache-accurate step skipping cuts build minutes materially. Of those, a platform team maintaining near-identical build yaml across forty repositories that wants one versioned module every repository calls instead and an engineering organisation migrating off a ci provider that does not want to rewrite every pipeline as part of the migration are not what Microsoft Defender is typically brought in for.

Answered from the vendors’ own pages

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.

Microsoft Defender: How much does Microsoft Defender Suite cost?

Microsoft Defender Suite costs $12/user/month (paid yearly), but requires existing Microsoft 365 E3 or equivalent base licensing. It includes endpoint protection, identity threat detection, email security, and SaaS application monitoring.

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.

Microsoft Defender: What add-ons are available for Microsoft Defender?

Microsoft Defender Vulnerability Management Add-on costs $2/user/month with annual commitment and includes a one-month free trial. Additional pay-as-you-go products include External Attack Surface Management, Cloud Security Posture Management, and Sentinel.

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.

Microsoft Defender: Is Defender included in Microsoft 365 E5?

Yes, Microsoft Defender Suite is included in Microsoft 365 E5 at $60/user/month (paid yearly with Teams). Prices may vary based on Microsoft agreements, requiring contact with Sales for customized quotes.

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.
