Spacelift IaC Platform

Spacelift is a specialized continuous integration and deployment (CI/CD) platform designed specifically for infrastructure-as-code (IaC) tools. Founded in 2020 by Marcin Wyszynski and Lukasz Dziedziak, Spacelift has raised over $20 million in funding and has become a leading platform for managing Terraform, OpenTofu, Pulumi, CloudFormation, and Kubernetes deployments. Unlike general-purpose CI/CD tools (like GitHub Actions or Jenkins) that require significant custom scripting for infrastructure workflows, Spacelift provides purpose-built features for IaC. Key features include: multi-IaC tool support (managing Terraform, OpenTofu, Pulumi, CloudFormation, Kubernetes manifests, and Ansible playbooks within a single platform), customizable run workflows (defining custom initialization, plan, apply, and destroy steps via runnable commands, enabling custom validation, testing, and integration), drift detection (periodically checking the actual infrastructure state against the declared IaC state and alerting on configuration drift), policy-as-code (using Open Policy Agent Rego policies to enforce compliance, security, and cost controls on infrastructure changes before they are applied), stacked dependencies (managing stacks that depend on each other, automatically triggering downstream stacks when upstream changes occur), module registry (a private module registry for sharing Terraform modules within an organization), worker pools (self-hosted runners for executing infrastructure changes within a private network or VPC for security), programmatic approach (Terraform state management, workspace isolation via isolated Docker containers per run), multi-cloud and multi-region (deploying infrastructure across AWS, Azure, GCP, and private clouds), Git integration (triggering runs on pull requests, commits, and merges with branch and tag filtering), and SSO and RBAC (enterprise authentication with role-based access control).
