The short version

  • Spacelift is free; Statsig starts at $150/mo.
  • Only Spacelift lists multi-tool orchestration; only Statsig lists feature Flags.
  • Where Spacelift falls short: three of the five tiers are quote-only, so a shortlist cannot be costed without entering a sales process with each vendor on it.
  • Where Statsig falls short: pro plan is limited to a single project, requiring Enterprise for multi-project support.
  • Prices and features on this page were last checked on 31 August 2026.

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

Statsig

  • Pro plan is limited to a single project, requiring Enterprise for multi-project support
  • Overage pricing on the Pro plan can become costly for high-event-volume products
  • Warehouse-native deployment and advanced access controls are gated behind custom Enterprise contracts
  • Free tier session replay and analytics retention are capped, pushing active teams toward paid tiers quickly

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.

Statsig: What does Statsig cost?

Statsig offers a free Developer tier, a Pro tier at $150/month with 5M included events and $0.05 per 1,000 events after that, and custom Enterprise pricing based on event or experiment volume.

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.

Statsig: Is there a free plan, and what are its limits?

The free Developer plan includes 2M events per month, unlimited flag and config checks, 50,000 session replays per month, and 1-year analytics data retention with unlimited seats.

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.

Statsig: How is usage metered on Statsig?

Statsig meters billable events including exposures with Metric Lifts enabled, log events from SDKs or imports, ingested warehouse metrics, and custom metrics; disabled flag checks are not metered.

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.
