Stately

verifiedFreemiumAPIstately.ai

Visual state-machine editor (built on XState) that lets teams design app logic as diagrams and export runnable JS/TS code.

What it does

Stately is a visual editor for designing application logic as state machines and statecharts, built on the open-source XState library. Diagrams can be simulated, turned into React app prototypes, and exported as executable JavaScript/TypeScript, with bidirectional sync so code and diagram stay aligned. AI can generate or modify state machines, and Enterprise adds self-hosting and SSO.

How to use: Open the browser-based visual editor and design flows with drag-and-drop or AI assistance. Simulate and test the design, then generate code or export to JavaScript, TypeScript, or React, and use GitHub Sync to keep diagrams and codebase aligned.
