Stately is a platform for visually building, simulating, and deploying application logic, centered around state machines and statecharts. Its goal is to quickly turn ideas into diagrams and code, and to serve as a single source of truth for teams to understand logic.
Purpose: Stately is used to design and deploy any type of logic, including frontend user flows, backend workflows, and more. Through a visual language, it enables all team members, regardless of technical background, to participate in logic design, eliminate information silos, and keep documentation and implementation in sync.
Main capabilities:
- Visual editor: A drag-and-drop interface that supports no-code creation of flows, rapid prototyping or gathering requirements, and simulating designs to test and iterate. Prototypes can be instantly tried out as automatically generated React applications.
- AI assistance: Guided by state machines, AI can help generate flow skeletons, suggest variants, discover edge cases, and even write code.
- Executable diagrams: Diagrams are executable, combining the strengths of text and visual tools. Logic runs using XState (an open-source library), with no lock-in. XState can be used on the frontend, backend, or in any JavaScript environment, and supports integration with frameworks such as React, Vue, and Svelte. It uses event-driven programming, state machines, statecharts, and the actor model to handle complex logic.
- Bidirectional updates: Bidirectional synchronization between code and visualization improves productivity. Code such as Redux and Zustand can be automatically visualized, so users can benefit even if they do not use XState.
- IDE extension: Brings Stately functionality into VS Code.
- Code generation: Generate React applications from diagrams, automatically generate tests, export JavaScript or TypeScript code, and sync codebases with GitHub.
- Debugging and inspection: Use Stately Inspector to inspect running applications and visualize communication between actors with sequence diagrams.
- Documentation and versions: Save versions as backups and history, export as Markdown stories, Mermaid diagrams, or JSON documents, and generate diagram summaries.
How to use: Users can create flows through the drag-and-drop editor without coding. They can simulate designs, generate React application prototypes, export code, and sync with GitHub. AI assistance runs through every stage. The product offers community diagram exploration, work sharing, Discord community support, and Office Hours events.
Use cases: Suitable for frontend interfaces that need to manage complex state, payment products, and business workflows, etc. Teams can use it to collaboratively design, communicate logic, generate tests, and maintain documentation.
Limitations: The materials do not provide specific information on pricing methods, prices, platform availability (such as whether it is web-only), specific performance, or technical limitations, so none is provided for now.
