Spacelift is an infrastructure-as-code (IaC) management tool used to build multi-IaC workflows for Terraform, OpenTofu, Ansible, Kubernetes, Terragrunt, CloudFormation, and Pulumi. It integrates with your VCS provider and references a directory containing your IaC configuration. It creates a predefined workflow for deployments in any cloud provider, using one of the supported IaC tools. Ship through code, ship through AI, govern both Set up your cloud integrations Choose your deployment model AI assistance at every step Even if you choose the traditional path, your AI assistant will be ready to help you at any time. Describe your infrastructure as code with your favorite IaC tool Connect to our MCP server or use our built-in AI Assistant Push your code to your VCS system Create, manage, and enforce policy Create a stack for your VCS repo Describe your infrastructure in natural language Choose automation level Infrastructure changes are applied at your providers See and govern everything, continuously Centralized state management Centralized state management Continuous monitoring Continuous monitoring Drift detection Drift detection Resource visibility Resource visibility Get a technical demo with an engineer Director of Engineering — Developer Platform Spacelift has enabled Checkout to scale from a handful of deployments per day to averaging over 500 per day. Trusted by top companies, including: Powerful components In Spacelift, stacks are responsible for configuring and deploying your workflow. With a full spectrum of tool integrations , you can have your choice of VCS provider and backend (Terraform, OpenTofu, etc.), configure versions, optionally configure what happens before and after every runner phase — and even attach cloud integrations for short-lived credentials, policies, and contexts. Elevated security, governance, and compliance Use policy as code to define the types of resources your workflows can create, the resource parameters, the number of approvals required for a run, what happens when a PR is open against a branch, and where to send notifications. Attach policies from the following categories to as many stacks as you want: Customizable workflow Add commands between your runner phases, bring your own image, or even configure the default workflow commands. This flexibility enables easy integration with any third-party tool. You can even define policies for workflows via custom inputs , and you never have to compromise. Streamlined orchestration Use stack dependencies to easily configure your EC2 instances and K8s clusters. Share outputs between dependent stacks. Nest those dependencies to trigger runs on child stacks when the parent stack finishes a run successfully. Transform your monolith deployment into multiple micro-deployments, making it easy to identify where problems arise. Your workflow potential is limitless! What do customers say? "With Spacelift, our platform team was able to deploy much faster and have better control over the resources that are deploying." Principal Engineer - Talkdesk Marcelo Almeida "Spacelift has been great in giving visibility and confidence in managing (IaC-deployed) resources and being sure that what you're running is what you need."

Senior Manager, Cloud Engineering at Discovery Education "Spacelift really provided the team with the right tools to do their jobs more efficiently and solve the problem of having control over IaC" Senior Director of Technical Operations - Bullhorn Let an engineer walk you through Spacelift Spacelift has enabled Checkout to scale from a handful of deployments per day to averaging over 500 per day. Director of Engineering - Developer Platform at Checkout.com Joe Hutchinson The great thing about Spacelift is it does what we need it to do without getting in the way. Once we had it installed and configured, it faded into the background of our workflow, letting us operate more efficiently with no hassle. DevOps engineering manager at SpotOn Alex Siegman We needed a way to create consistent run environments and provide auditing. And we increasingly needed to be able to hand off approvals for runs to developers and security staff. Spacelift has made it simple, so it’s had a positive impact on the company as a whole.

Frequently Asked Questions How does Spacelift run in my environment? Spacelift is a control plane that executes runs on workers. You can use shared workers or run private worker pools in your cloud for full data path control, with end-to-end encryption of run payloads. If your repos are private to the internet, a lightweight VCS agent lets Spacelift reach them securely. Spacelift is a control plane that executes runs on workers.

Which IaC tools can I use with Spacelift? Spacelift supports Terraform, OpenTofu, Terragrunt, Pulumi, AWS CloudFormation, Kubernetes, and Ansible, so you can standardize workflows across mixed tooling. Spacelift supports Terraform, OpenTofu, Terragrunt, Pulumi, AWS CloudFormation, Kubernetes, and Ansible, so you can standardize workflows across mixed tooling. What is a “run” in Spacelift? A run is a job that can preview or change infrastructure. Common types are proposed runs for safe previews and tracked runs for actual deployments, with optional approvals in between.

How does drift detection work in Spacelift? Spacelift detects drift by executing scheduled proposed runs against finished state and flagging any differences. You can review findings in the UI and optionally reconcile, and it works on private workers.

Spacelift supports GitHub, GitLab, Bitbucket, and Azure DevOps, including self-hosted and SSH. How do I share secrets and common config across Spacelift stacks? Use Contexts to share environment variables, mounted files, and hooks across stacks and modules. Attach a context wherever you need it to avoid copy-pasting configuration. Use Contexts to share environment variables, mounted files, and hooks across stacks and modules. Attach a context wherever you need it to avoid copy-pasting configuration. How does policy-as-code work in Spacelift? Spacelift uses Open Policy Agent with Rego to enforce rules at every stage. You write readable policies that check plans, control who can approve or apply, govern which stacks can touch which accounts, and block risky changes before they land. Policies evaluate in the worker context with full input data, return clear messages to engineers, and become part of your compliance record.
