Windmill

Windmill is an open-source, code-first orchestration platform that lets engineering teams build and run internal software — scripts, workflows, internal apps, and data pipelines — all in one place. It supports Python, TypeScript, Go, PHP, Bash, SQL, and 20+ other languages, turning a single file into an API, a triggerable job, and an auto-generated UI with no boilerplate. Windmill is self-hostable via Docker or Kubernetes and also available as a managed cloud service, with Git-based collaboration and full infrastructure-as-code support.

• Multi-language scripts — Write scripts in Python, TypeScript, Go, Bash, SQL, and more; each script automatically becomes an API endpoint and a triggerable job with an auto-generated form.
• Visual flow editor — Build DAG-based workflows with a drag-and-drop flow editor, supporting branching, loops, approval steps, error handlers, and restartable flows.
• Low-code app builder — Create internal UIs with a drag-and-drop app editor that connects directly to scripts and flows, with support for custom React components (Enterprise).
• Scheduling and triggers — Run jobs on cron schedules or trigger them via webhooks, email, Postgres, WebSocket, Kafka, MQTT, SQS, NATS, GCP, and Azure Event Grid.
• Git sync and local dev — Sync your entire workspace to a Git repository; develop locally with the Windmill CLI and deploy with wmill sync push.
• Granular RBAC — Organize work with workspaces, folders, groups, and path-based ACLs; supports SSO, SAML/SCIM, custom OAuth, and external JWT auth.
• Full observability — Every execution is logged, tracked, and searchable; Enterprise adds audit logs, Prometheus metrics, OpenTelemetry tracing, and S3 log storage.
• High-performance orchestration — Engineered to be the fastest job orchestrator in the industry; scales from a single VPS to 1,000-node Kubernetes clusters with autoscaling and dedicated worker groups.
• 100+ integrations — Built-in connectors for PostgreSQL, Snowflake, S3, Slack, GitHub, Supabase, and 100+ more; no custom SDKs required.
• AI agent support — Build and orchestrate AI agents and data pipelines alongside traditional workflows in the same platform.
