Script editor
Code editor with built-in infrastructure
Every function you write gets a parameters UI, an API endpoint, triggers, one-click deployment, and monitoring out of the box.
query_db.tsWrite code, get infrastructure
Windmill provides a full-featured code editor in the browser where you write scripts like in a classic IDE. Built on Monaco, it includes LSP autocompletion, linting, and formatting.
From a single script, Windmill automatically generates the infrastructure to make it production-ready:
Auto-generated UI
API endpoint
Triggers
Instant testing
One-click deployment
Versioning
Dedicated workers
Monitoring
Write in any language
Write your logic in TypeScript (Bun, Deno), Python, Go, Bash, SQL, or 20+ other languages. Each language runs on its real runtime with full LSP support in the browser editor.
Read the docsReal dependencies, real runtimes
Scripts run on real runtimes, not sandboxed interpreters. You can use any dependency from npm, PyPI, Go modules, or Cargo, including packages from private registries. Inspectable lockfiles are generated per script for reproducibility, and can be centrally managed with workspace dependencies.
Read the docsAuto-generated UI
Scripts automatically get a form UI from their function signature. Useful for quick testing during development and for exposing scripts to operators as standalone tools, no frontend needed.
Read the docsShared resources
Parameters typed as a resource show a dropdown of configured connections in the UI. Credentials are centrally managed, encrypted at rest, and injected at runtime. A database, API key, or OAuth2 connection is configured once and reused across any script that needs it.
Read the docsReal-time logs and instant testing
Scripts can be tested directly from the editor. Logs stream in real-time and results are displayed instantly.
Read the docsIntegrated debugger
The integrated debugger for Python and TypeScript (Bun) supports breakpoints, step over, step into, step out, and continue controls. A variables panel shows live values in the current scope, and the console allows evaluating expressions while paused.
Read the docsTriggers
Any script or workflow can be triggered by schedules, webhooks, message queues, database changes, emails, and more.
Read the docsAPI endpoint for every script
Every deployed script is automatically exposed as a REST endpoint. Call any script programmatically with a simple HTTP request, authenticate with tokens, and integrate Windmill scripts into any external system or CI/CD pipeline without extra configuration.

One click deployment and versioning
Deploy and your script is immediately available. Each save creates a new immutable version with a unique hash.

Dedicated workers
Each script runs on an isolated worker with the full CPU and memory available to it. Scale horizontally and eliminate cold starts.

Built-in granular monitoring
Every execution is logged with its inputs, outputs, duration, and status. Run history is searchable and filterable.
