What is an AI agent on Windmill?
Windmill provides enterprise-grade infrastructure to build AI agents around any LLM, including self-hosted models. Give your agents access to tools written in any language, connect them to your databases and APIs, compose them into flows alongside scripts and workflows, or run them in isolated sandboxes.
Your agents run on the same platform as the rest of your infrastructure, with full observability on every tool call and LLM request, RBAC, audit trails and versioning built in.

Two ways to build AI agents
Use the visual AI builder with tools for structured agent loops, or run full Claude Code, Codex or Opencode inside sandboxes for maximum autonomy. Both can be used as steps of a flow.
Visual AI builder with tools
The AI agent step is a ready-to-use node in the flow editor. Build agent workflows visually by combining agent steps with branching, approval steps, error handling and any other flow step.

Run coding agents inside isolated sandboxes with full capabilities: bash, code writing, file editing. Cached snapshots for instant startup, persistent volumes across runs and scoped permissions.

Agents can use Windmill scripts and MCP servers as tools. Scripts are written in TypeScript, Python, Go, SQL or any supported language. Windmill reads each script's typed function signature and generates the tool schema the LLM sees. MCP servers expose their own tool definitions and are auto-discovered when connected.

An AI chatbot built entirely on Windmill. The frontend is a full-code React app, the backend is a flow that calls an AI model with Windmill scripts as tools.

Built for production
Every agent runs within a platform built for enterprise requirements: immutable versioning, role-based access control, full audit trails, SSO and self-hosting. No extra setup needed.
Versioning and deploy
Every agent version is immutable and addressable by hash. Deploy from the UI, the CLI or Git sync. Roll back to any previous version instantly. Sync your workspace with GitHub or GitLab and use your existing code review workflows.
Learn more about deployment and versioningFull observability
Every run is logged with inputs, outputs, duration and status. Real-time execution logs stream as your agent runs. Set up error handlers to send alerts on failure. Audit trails track who ran what and when.

Control who can view, edit and run each agent with role-based access control. Organize agents into folders with group-level permissions. Authenticate users with SSO. Every action is recorded in the audit log.

More you can build on Windmill
AI agents are just one use case. The same platform powers internal tools, data pipelines, workflows and triggers.
Write scripts in TypeScript, Python, Go, Bash, SQL and trigger them from webhooks, schedules, queues or the auto-generated UI.
Build production-grade internal apps with backend scripts, data tables and React, Vue or Svelte frontends.
Orchestrate ETL jobs with parallel branches, DuckDB queries and connections to any database or S3 bucket.
Chain scripts into flows with approval steps, parallel branches, loops and conditional logic.
Run cron jobs with a visual builder, execution history, error handlers, recovery handlers and alerting.
