The short version
- Only Spacelift has a free tier, so it costs nothing to try first.
- Each has a real cost: Resolver kroll ownership since 2022 means the product is sold alongside risk consulting services, so buyers who want software with no services attach should expect that conversation and should price the licence separately in negotiation.; 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.
- They diverge on capability: Resolver covers Incident management, Spacelift covers Multi-tool orchestration.
- 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.
Resolver
- Kroll ownership since 2022 means the product is sold alongside risk consulting services, so buyers who want software with no services attach should expect that conversation and should price the licence separately in negotiation.
- Configuration flexibility comes at the cost of implementation time, with deployments commonly running several months and typically requiring vendor or partner services, so the first-year cost is well above the annual licence.
- Module-based pricing means the platform gets expensive quickly once you add audit, compliance and continuity to a security-led purchase, and modules bought later rarely carry the discount of the original deal.
- The IT and cyber compliance side is thinner than dedicated tools, so organisations chasing SOC 2 or ISO 27001 evidence automation will find it does not replace a Drata or Vanta.
- Reporting is capable but the drag and drop builder has a real learning curve, and organisations that do not train an internal administrator end up raising support tickets for changes that should be self-service.
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.

Answered from the vendors’ own pages
Resolver: Who owns Resolver?
Kroll, which acquired it in 2022. It is marketed as a Kroll business and sold alongside Kroll risk and investigations services.
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.
Resolver: What does Resolver cost?
Pricing is not published. It is quoted by module and user count on an annual or multi-year enterprise agreement, with implementation charged separately.
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.
Resolver: Is Resolver a SOC 2 compliance tool?
No. It is a risk, incident and investigations platform. Automated evidence collection for security certifications is not its strength.
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.
Resolver: How long does implementation take?
Months rather than weeks for a multi-module deployment, and most customers use vendor or partner services to configure it.
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.
