About Massdriver

Massdriver is an internal developer platform and platform orchestrator. Platform teams publish the Terraform, OpenTofu, and Helm they already write to a catalog; developers and AI agents provision from it with policy enforced before every deploy. Self-hosted or managed. Platform teams encode their security, compliance, and cost requirements into the modules once. Developers and AI agents pick from the catalog, policy runs before anything is created, and every deploy is recorded with who proposed and who approved it. Massdriver generates an ephemeral pipeline per deploy, so there are no standing CI/CD pipelines to maintain. Run it self-hosted, on-prem, or in your cloud.
