stately.ai

stately.ai is a visual development platform that helps teams design, build, and maintain complex application logic through state machines and workflows. Instead of writing code manually, you can use their drag-and-drop editor to create visual diagrams that represent how your application should behave. These diagrams become executable specifications that can generate actual code, tests, and even prototype React applications automatically. The platform supports JavaScript and TypeScript development with integrations for popular frameworks like React, Vue, and Svelte.

What makes stately.ai stand out is its bidirectional workflow—you can work visually in the editor or directly in code, and changes sync between both representations. The AI capabilities help scaffold behavior, suggest variants, and handle edge cases. The VS Code extension brings these visual benefits directly into your development environment, and you can automatically visualize existing codebases using Redux or Zustand. The platform generates comprehensive tests and provides inspection tools for debugging running applications.

This tool primarily benefits software development teams working on complex frontend or backend logic. It's particularly valuable for product teams that need to maintain alignment between design, documentation, and implementation. Real-world use cases include building payment processing flows, designing user onboarding sequences, creating IoT device management logic, and maintaining complex business workflows that require clear visualization and robust testing.
