About Stately.ai
What is Stately.ai?
Stately.ai is a SaaS platform that turns ideas into executable diagrams and code. It lets you visually design frontend user flows, backend workflows, and complex logic using a drag-and-drop editor backed by state machines (powered by XState). AI assists in generating flows, tests, and React UIs from your visual designs.
What problem does it solve?
Stately.ai bridges the gap between non-technical contributors and developers by providing a shared 'source of truth'—living diagrams that stay in sync with code. It eliminates silos, reduces miscommunication, and keeps documentation always up-to-date. Teams no longer have to choose between visual clarity and code accuracy.
Who is it for?
Stately.ai is ideal for frontend and full-stack developers, product managers, and designers who need to map out complex logic (e.g., multi-step forms, onboarding flows, checkout sequences) and generate production-ready code. It is NOT for teams who need no-code end-user app builders or hobbyists without JavaScript/TypeScript apps. Best for React, Vue, Svelte users.
Real use cases
Designing a checkout flow: drag logic, simulate edge cases, and auto-export to XState for your React app. Debugging a Zustand-based app: visualize state transitions with Stately Inspector. Generating test coverage: AI creates tests from your state machine diagram, keeping coverage robust.
Key features
- Visual modeler — Drag-and-drop state machine editor for teams; no code required to start.
- AI generation — Scaffold flows, suggest variants, and turn up edge cases using AI (3 generations/mo on Community, 1,000 on Pro).
- XState integration — Run diagrams with XState, the industry-standard JS/TS library; export to JavaScript/TypeScript.
- Bidirectional sync — Changes to code update the diagram and vice versa; supports Redux, Zustand, and more.
- Live simulation & React app generation — Test your logic instantly as an auto-generated React app.
- VS Code extension — Edit and preview state machines directly inside your IDE.
- Inspect & debug — Stately Inspector visualizes communication between actors in running apps.
