The short version

  • 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.; Whimsical the free plan is capped at 3 team boards, 3 teams and 10 guest seats
  • They diverge on capability: Spacelift covers Multi-tool orchestration, Whimsical covers Flowcharts.
  • Prices and features above 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.

Whimsical

  • The free plan is capped at 3 team boards, 3 teams and 10 guest seats
  • File uploads are limited to 5MB per file and 1GB in total on the free plan
  • Version history on the free plan goes back 7 days
  • Voting, the timer, private teams, the GitHub integration, password-protected files and watermark removal all need Pro at $10 per editor per month
  • SSO and SAML are Business tier only at $20 per editor per month

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.

Whimsical: What are Whimsical's pricing tiers?

Whimsical offers three plans: Free at 0 dollars per month per editor, Pro at 10 dollars per month per editor, and Business at 20 dollars per month per editor.

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.

Whimsical: What is included in the Free plan?

The Free plan allows creation of up to 50 board objects and 50 doc blocks per month, includes watermarked exports, and provides 7-day version history. Storage is limited to 1GB.

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.

Whimsical: What features unlock in the Pro plan?

The Pro plan removes the object creation limits, provides unlimited board objects and doc blocks, removes watermarks from exports, extends version history to 90 days, and offers 100GB of storage.

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.

Whimsical: What security and team features come with Business?

The Business plan adds private teams, SAML single sign-on, SCIM and advanced security controls, unlimited version history, priority support, and a dedicated success manager. Storage starts at 2TB.

Source
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.

Whimsical: Do discounts apply for annual billing?

Yes, annual billing offers a 17 percent discount compared to monthly rates. Additionally, nonprofits receive a 20 percent discount and students and teachers get full access.
