What is Spacelift?

Spacelift opens an AI-native operations layer alongside its IaC pipeline, betting on natural-language infra under policy guardrails.

Spacelift is an IaC management platform consolidating a year of incremental UX work — auto-attach for cloud integrations, command palette, OIDC customization, in-platform Learn — while making a sharp directional bet on AI-native operations through Spacelift Intelligence (Infra Assistant plus Intent). Terragrunt has been promoted to a first-class framework with native state management.

What is Depot?

Depot turns its build-acceleration compute into a metered backend for AI agents.

Depot is shipping fast across two fronts: hardening its CI platform and opening its compute to AI workloads. Recent CI work includes native step retries, durable cache disks, and a generally available API and CLI with full dashboard parity. On the AI front it added SOCI v2 to cut startup time for large CUDA and PyTorch images and launched a Sandbox SDK to run untrusted or agent-generated code in ephemeral, billed sandboxes.

Spacelift vs Depot: editorial side-by-side

Spacelift opens an AI-native operations layer alongside its IaC pipeline, betting on natural-language infra under policy guardrails.

◆ Current state

Spacelift is an IaC management platform consolidating a year of incremental UX work — auto-attach for cloud integrations, command palette, OIDC customization, in-platform Learn — while making a sharp directional bet on AI-native operations through Spacelift Intelligence (Infra Assistant plus Intent). Terragrunt has been promoted to a first-class framework with native state management.

◆ Where it's heading

The team's framing is clear: GitOps and IaC remain the production rail, but a parallel AI-velocity rail handles experiments, sandboxes, and POCs. Intent runs against provider schemas under Spacelift's policy and audit guardrails — the platform itself is what makes the AI rail safe to use. Combined with Templates (immutable, lifecycle-managed deployments) and Terragrunt parity, Spacelift is positioning as the governance layer for whatever IaC the team chooses, including no-code natural language.

◆ Prediction

Expect rapid Intent capability expansion — more cloud providers, deeper policy integrations — and an MCP-first API push as agent-driven infra becomes a real category. Pricing or tier reshuffles around AI usage are likely as Intelligence moves from early access toward paid-only consumption.

Depot turns its build-acceleration compute into a metered backend for AI agents.

◆ Current state

Depot is shipping fast across two fronts: hardening its CI platform and opening its compute to AI workloads. Recent CI work includes native step retries, durable cache disks, and a generally available API and CLI with full dashboard parity. On the AI front it added SOCI v2 to cut startup time for large CUDA and PyTorch images and launched a Sandbox SDK to run untrusted or agent-generated code in ephemeral, billed sandboxes.

◆ Where it's heading

Depot is extending from build and CI acceleration toward being a general compute backend for agents. The Sandbox SDK, the agent-friendly GA API, and ML-image startup optimizations point the same way: sell fast, isolated, metered compute that AI tools and pipelines can drive programmatically. The CI improvements keep the core product sticky while the platform broadens.

◆ Prediction

Expect the Sandbox SDK to move toward general availability with more language and filesystem surface, and continued convergence of CI and sandbox compute under one metered, API-first platform.
