Spacelift: Infrastructure Automation Ledger 2026 Scorecard

Part of the Infrastructure Automation Ledger (edition 2026-10-16). How the scores work: methodology.

Snapshot

Type: product
Owner: Spacelift, Inc. (private, venture backed; $51M Series C led by Five Elms Capital, 2025-07; no acquisition found)
Engine: none of its own; orchestrates Terraform, OpenTofu, Terragrunt, Pulumi, AWS CloudFormation, Kubernetes (Helm, Kustomize) and Ansible
Licence: proprietary SaaS; Self-Hosted only on Enterprise+; Free plan with 2 users and 1 public worker; spacectl and the Terraform provider are open source
Latest release: SaaS, changelog entry 2026-10-14; spacectl 1.28.0 (2026-10-12); terraform-provider-spacelift 1.57.0 (2026-10-09)
Support lifecycle: no published support windows; Self-Hosted receives features only with its next release; private workers must move to HTTP long-polling by 2027-01-01
Next milestone: ARM/Bicep and unmanaged resources listed as coming soon without dates; private worker transport change due 2027-01-01
Targets: Terraform MPL releases up to 1.5.7 only, by vendor decision after the 2023-08 BSL change (docs read 2026-10-15); OpenTofu, treated as its own stack vendor since 2026-10-09; Pulumi, CloudFormation, Kubernetes, Ansible; private workers on every paid plan reach vCenter, Proxmox VE and other on-prem endpoints
Tier: IaC management platform
Archetype: Dependable builder
Evidence grade: B. Pricing page, docs, changelog and GitHub release feeds were read from primary sources (2026-10-15). Funding and the 2025 launches come from press coverage. The 2021 and 2022 capability states are inferred from later vendor pages, because the dated changelog starts in 2025.

Centre of gravity: AI (4), Provisioning breadth (3), Packaging (3)
Blind spots (no items): Language, Bare metal
Driver mix: Vision 20%, Customer need 40%, Market window 25%, Upstream 5%, Portfolio 10%
Idea-to-need index: 0.24 (0 = demand-pulled, 1 = thesis-pushed)

Credibility: 19.0 / 25

Criterion	Score	Basis
Cadence	4.5	Dated changelog entries almost every week to 2026-10-14; spacectl and the Terraform provider release monthly
Roadmap transparency	3	Public changelog and feedback board; the coming soon items (ARM/Bicep, unmanaged resources) carry no dates
Say-do	4	Intent went from early access (2025-10-08) to GA (2026-03-18) in five months; Self-Hosted and Ansible shipped as announced; two coming soon items still pending
Velocity	4.5	Intelligence, remote MCP, templates, Flows, Kubernetes autoscaling and notification policies all within 2026
Lifecycle stability	3	Forced worker transport change by 2027-01-01 and the old MCP endpoint removed after 2026-08-01; plan line-up changes in 2026 are reported by a third-party tracker only

Commercial risk: 12.0 / 25 (lower is better)

Criterion	Score	Basis
Price and licence volatility	2.5	Official pricing page is undated; Starter+ listed at $20,000 with the period stated only in the FAQ; a third-party tracker reports tier churn in 2026 (unverified)
Purchase constraints	3	Free plan limited to 2 users; the entry paid tier is an annual subscription; Business and up by quote; Self-Hosted and air-gapped only on Enterprise+
Channel and access	2	Direct sales; a partner programme exists with unpublished terms; no open binary except spacectl and the provider
Owner stability	2	Independent and venture backed since 2021; the $51M Series C of 2025-07 adds exit pressure; no acquisition found
Cost of staying supported	2.5	SaaS updates itself; Self-Hosted gets features only with its next release; worker transport migration required by 2027-01-01

Technical lock-in: 7.0 / 25 (lower is better)

Criterion	Score	Basis
Formats	1	Standard Terraform, OpenTofu, Pulumi and Ansible code and state; stacks, contexts and Spaces are Spacelift objects
Export path	1.5	Code and state stay yours and the Terraform provider exports configuration; policies, contexts and worker pools need a rebuild elsewhere
Stack coupling	2	Runs, policies, contexts and worker pools bind to Spacelift APIs; Rego policies are portable in principle
Hardware / cloud coupling	0.5	Any cloud; Self-Hosted on AWS, Azure, GCP or Kubernetes; air-gapped on Enterprise+
Skills and tooling coupling	2	Engine skills plus Rego, Spacelift policy types and Flows

Integrator fit: 14.0 / 20

Criterion	Score	Basis
Partner programme openness	3	A programme exists; its terms are not published
Multi-tenancy and self-service	4.5	Spaces, blueprints, templates and unlimited users on paid plans
API and infrastructure-as-code	4.5	GraphQL API, Terraform provider (1.57.0), spacectl and a remote MCP server
Skills and certification	2	Documentation and training; no certification programme found

AI leverage: 9.5 / 20

How the product uses AI, scored per year like capability. Only GA counts.

Criterion	2019	2022	Today	Latest step
AI code and plan generation	n/a	0	3	2026: 2026-03: Intent GA generates and applies infrastructure from natural language under Intent policies; Infra Assistant Build mode carries no GA label
AI platform stack	n/a	0	1	2026: 2026-04: bring-your-own-model through AWS Bedrock; a Spacelift-provided model with a $10 monthly budget on Free
AI-assisted operations	n/a	0	2	2026: 2026-03: Intelligence covers drift management, policy creation and troubleshooting; the docs give no GA label, so half credit
Agent openness	n/a	1.5	3.5	2026: 2026-05: remote MCP server at /mcp with per-user OAuth, an mcp:read scope and Intent policies; GA label not stated

Year by year: 2021: 1.5 · 2022: 1.5 · 2023: 1.5 · 2024: 1.5 · 2025: 2.5 · 2026: 9.5

AI say-do, 2023 to 2026: 5 AI items announced; 4 GA, 1 still preview, 0 pending, 0 dropped. Spacelift's docs do not label release stages; the remote MCP server and Infra Assistant are open to every account and are counted as shipped, the MCP tools parameter is labelled Alpha.

Spacelift has the widest AI surface in this group: natural language provisioning that reached GA, an assistant in the UI and a remote MCP server with per-user OAuth and policy checks. What is missing is a GA label on the assistant and the MCP server and a description of how AI actions appear in the audit trail.

Reading

Spacelift is the broadest platform in this group: six engine types, a self-hosted and air-gapped option, and an AI record where the headline item (Intent) reached GA five months after early access. Its customer-driven changelog, almost weekly since 2025, earns the highest credibility score of the platforms. The scores are held back by entry pricing (a $20,000 annual Starter+ tier above a two-user Free plan) and by self-hosting being limited to Enterprise+. The one thing to check before signing is the Self-Hosted release lag against SaaS, together with the private worker transport change due by 2027-01-01.

Open questions and items to re-score

Period of the $20,000 Starter+ price: the pricing page gives none, the FAQ calls it annual.
GA status of Infra Assistant and the remote MCP server: the docs label neither.
First public release date: not found; capability before 2023 is inferred from later vendor pages.
FedRAMP authorisation and signed build provenance are vendor statements that could not be verified.
Plan line-up changes in 2026 (Team removed, Starter+ and Enterprise+ re-added) rest on a third-party tracker.
ARM/Bicep support and unmanaged resource detection are listed as coming soon without dates.
