Rationale
Windmill is an open-source developer platform that directly competes with Retool, offering similar functionalities for building internal tools, workflows, and UIs. It explicitly states itself as an 'Open-source alternative to Retool' and provides features like turning scripts into webhooks, workflows, and UIs, supporting various programming languages for customization, and offering self-hosting options. The platform's description and features align very closely with all the 'must-have' and 'other' features of Retool, including API/database integrations (referred to as resources), drag-and-drop UI building (auto-generated UIs from script parameters and low-code UI building), extensive code customization (Python, TypeScript, Go, Bash, SQL, GraphQL), robust security (sandboxing, secrets encryption, SSO/OAuth, RBAC), flexible deployment (Docker, Kubernetes, binaries), debugging tools (logs, performance), version control (GitHub repo sync), audit logs (implied by security and enterprise features), workflow automation (flows, cron, webhooks), mobile support (implied by UI building), prebuilt components (implied by UI builder), AI assistance (AI chat system prompt), custom theming (implied by UI customization), and partner portals (secure, white-labeled portals).
