Docker features

  • Docker Sandboxes. MicroVM isolation with locked-down network and filesystem for each agent session.
  • Docker AI Governance. Console for policy enforcement, identity-bound audit logs and zero per-machine setup.
  • Docker Hardened Images. Minimal, signed images with SLSA Level 3 provenance and continuous patching.
  • Docker Desktop. Full dev loop with Engine, Kubernetes, Compose and GUI on local machines.
  • Docker Build Cloud. Cloud-based build service with free trial minutes for CI/CD pipelines.
  • Testcontainers Cloud. Runtime environment for container-based tests with allocated minutes per plan.

Windmill features

  • Multi-language scripts. Run Python, TypeScript, Go, Bash, SQL, PHP and more as API endpoints with full code control.
  • Visual DAG workflows. Design dependency graphs in a flow editor or as code, with retries, approvals and parallel branches.
  • Low-code app builder. Create React or Svelte front-ends with drag-and-drop and code, backed by existing scripts and flows.
  • AI agent integration. Connect to 12+ LLM providers or your own OpenAI-compatible endpoint to run scripts as agent tools.
  • Built-in observability. Each run logs inputs, outputs, traces and metrics; alerts can be sent to Slack, Teams or email.
  • Git-based collaboration. Workspaces fork like Git branches; changes are reviewed, merged and deployed to staging and prod.
  • Self-hosted infra. Deploy via Docker, Fargate or Kubernetes with YAML-defined worker groups and autoscaling.
  • Enterprise security. Supports SSO, SAML/SCIM, audit logs, SOC 2 Type II and external secret backends.
