Windmill

Windmill is a code-first internal software orchestration platform that unifies scripts, workflows, internal apps, data pipelines, and AI agents in a single open-source system, serving over 4,000 organizations including 300-plus enterprise customers. The platform is engineered as the fastest job orchestrator and workflow engine in the industry, auto-scaling from a single-node VPS to 1,000-node Kubernetes clusters with dedicated worker groups for task isolation. Scripts written in TypeScript, Python, Go, Bash, or 20-plus other languages are automatically converted into API endpoints, triggerable jobs, and auto-generated forms without boilerplate. The entire workspace is version-controlled in Git with full infrastructure-as-code support, enabling local development with Claude Code or Codex CLI and deployment via wmill sync push. Granular role-based access control with path-based ACLs, encrypted shared resource management for API keys and credentials, and workspace-level PostgreSQL databases enable secure multi-team collaboration. Real-time observability logs every execution with searchable audit trails and Slack, email, and Teams alerting. Customers include Zoom, where Demo Platform Product Manager Frederic Louks schedules drip hydration tasks; Photoroom, where Co-Founder and CTO Eliot Andres runs business-critical automations self-hosted; Pave, where Staff Platform Engineer Lewis Ellis runs 100-plus scripts and 15-plus crons across teams; Investing.com, where CTO Yonathan Adest orchestrates AI content processing pipelines; Kahoot Motimate; CFA Institute; Axians; and Panther Labs. The company is Y Combinator-backed with funding from Gradient Ventures and Bessemer Venture Partners, and is SOC 2 Type II compliant.
