The short version

  • Only Spacelift has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; WorkOS authKit free tier limited to 1 million monthly active users; additional millions cost $2,500/month

Where each one falls short

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

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.

WorkOS

  • AuthKit free tier limited to 1 million monthly active users; additional millions cost $2,500/month
  • Per-connection pricing for SSO and Directory Sync ($125–$50 each) scales poorly for enterprises with many identity providers
  • Audit logs require separate subscription at $125/month per SIEM connection or $99/month per 1 million events
  • Radar fraud protection billed separately at $100/month per 50,000 additional checks beyond 1,000 free checks
  • Custom domain feature requires $99/month subscription
  • Requires annual commitment for SLA and support guarantees; pay-as-you-go tier lacks uptime guarantee

Answered from the vendors’ own pages

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.

WorkOS: How quickly can I implement WorkOS SSO?

Developers can implement single sign-on in minutes instead of months. Multiple customers report setting up SSO in less than a week, with WorkOS handling the complexity of SAML and OIDC protocols.

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.

WorkOS: What SDKs does WorkOS provide?

WorkOS offers SDKs for Node.js, Python, Ruby, Go, PHP, Java, and .NET.

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.

WorkOS: Does WorkOS support SCIM provisioning?

Yes. WorkOS supports SCIM provisioning integration with systems like Okta and Entra ID for automated user management.

Source
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.
