The short version

  • Each has a real cost: GitLab CI/CD compute minute quotas for Premium and Ultimate tiers not disclosed in documentation; Spacelift users are unlimited and private workers are metered, so deployment concurrency rather than headcount drives the bill, which inverts how most engineering budgets are built and is easy to under-forecast.

Where each one falls short

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

GitLab CI/CD

  • Compute minute quotas for Premium and Ultimate tiers not disclosed in documentation
  • Additional compute minutes beyond quota incur charges; exact pricing not specified

Spacelift

  • Users are unlimited and private workers are metered, so deployment concurrency rather than headcount drives the bill, which inverts how most engineering budgets are built and is easy to under-forecast.
  • There is no affordable paid entry point. The free tier stops at two users and the next tier is a five-figure commitment with nothing in between.
  • Three of the five tiers are quote-only, so a shortlist cannot be costed without entering a sales process with each vendor on it.
  • The self-hosted build lags the hosted one, has no public worker pool and lacks the Azure and Google Cloud integrations available in the SaaS product, with OIDC federation offered as the workaround.
  • Stacks, Rego policies, Blueprints, Spaces and Spacelift-managed state are proprietary constructs, so leaving means rebuilding the orchestration layer rather than pointing it at a different runner.

Questions people ask

Is GitLab CI/CD or Spacelift better?
Neither clearly leads. GitLab CI/CD starts at Free and Spacelift at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, GitLab CI/CD or Spacelift?
GitLab CI/CD starts at Free and Spacelift at Free.
Does GitLab CI/CD or Spacelift run on more platforms?
GitLab CI/CD runs on Web. Spacelift runs on Web, Self-hosted, Cloud.
Can I use GitLab CI/CD for free?
Both have a free tier, so you can try either at no cost before committing.
What is GitLab CI/CD best used for?
GitLab CI/CD is most often used for reducing open source project infrastructure costs with public project discounts, enforcing monthly ci/cd spending limits and quota notifications, allocating compute minutes to open source contributors affordably, forecasting ci/cd spending patterns across multiple projects. Of those, reducing open source project infrastructure costs with public project discounts and enforcing monthly ci/cd spending limits and quota notifications are not what Spacelift is typically brought in for.
What can GitLab CI/CD do that Spacelift cannot?
Spacelift covers Multi-tool orchestration, Policy as code, Private workers, Spaces.

Answered from the vendors’ own pages

GitLab CI/CD: How many GitLab CI compute minutes does the free tier include?

The free tier of GitLab CI includes 400 compute minutes per month for free tier namespaces on GitLab.com.

Source
Spacelift: How is Spacelift priced?

By tier and by private worker count rather than per user. Users are unlimited on every paid plan. The published figure on the pricing page carries no period label, and the FAQ describes the tier as an annual subscription, so confirm the period in writing.

GitLab CI/CD: What is the cost factor for different GitLab CI runner types?

Linux x86-64 small runners cost 1x; medium runners cost 2x; large runners cost 3x. macOS and Windows runners have cost factors of 6-12x and are in beta status.

Source
Spacelift: Does it support OpenTofu?

Yes, and Spacelift sponsors the OpenTofu project, which is a substantive hedge for anyone avoiding Terraform under the Business Source Licence.

GitLab CI/CD: Do public open-source projects get discounts on GitLab CI compute minutes?

Public open-source projects receive a 0.5x discount on compute minutes. Public forks of GitLab open-source projects receive a 0.008x discount.

Source
Spacelift: Is there a self-hosted version?

Yes, described as carrying Enterprise functionality, but it is priced on request and lags the hosted product on cloud integrations.

Spacelift: Why not just use the CI system we already have?

That is the real comparison. General purpose CI handles state, drift, approval gates and concurrency control for infrastructure poorly, and whether that is worth a five-figure floor depends on how much infrastructure change your organisation actually ships.

Spacelift: What happens to our pipelines if we leave?

They do not port. Rego policies, Blueprints, Spaces and managed state are Spacelift constructs and the orchestration has to be rebuilt elsewhere.
