The short version

  • 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.; HCP Terraform legacy free version deprecated; no current freemium tier
  • 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

  • An engineering organisation migrating off a CI provider that does not want to rewrite every pipeline as part of the migrationnot HCP Terraform
  • A team whose engineers waste hours pushing commits to debug CI-only failures and needs to reproduce the exact run locallynot HCP Terraform
  • A monorepo where most commits touch a small subset of services and cache-accurate step skipping cuts build minutes materiallynot HCP Terraform

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.

HCP Terraform

  • Legacy free version deprecated; no current freemium tier
  • New users receive $500 credit but still require usage to continue service
  • Terraform Enterprise requires custom pricing

Questions people ask

Is Dagger or HCP Terraform better?
Neither clearly leads. Dagger starts at Free and HCP Terraform at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Dagger or HCP Terraform?
Dagger starts at Free and HCP Terraform at Free.
Does Dagger or HCP Terraform run on more platforms?
Dagger runs on Linux, macOS, Windows, Self-hosted. HCP Terraform runs on Web.
Can I use Dagger for free?
Both have a free tier, so you can try either at no cost before committing.
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 HCP Terraform is typically brought in for.
What can Dagger do that HCP Terraform cannot?
Dagger covers Pipelines as code, Local and CI parity, Content-addressed caching, Dagger Functions and modules.

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.

HCP Terraform: How much does HCP Terraform cost?

HCP Terraform uses per-resource pricing starting at $0.10/month/resource for Essentials, $0.47/month/resource for Standard, and $0.99/month/resource for Premium.

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.

HCP Terraform: Does HCP Terraform offer a free tier?

No, the legacy free version has been deprecated. However, new users receive $500 credit to try the service.

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.

HCP Terraform: What does the Standard plan include?

Standard plan at $0.47/month/resource includes unlimited modules, module deprecation, team notifications, no-code provisioning, and Waypoint templates.

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.
