## Overview

Stately started as a visual editor for XState, the popular JavaScript state machine library, and has grown into a full modeling and reasoning layer for application logic. Instead of describing behavior in prose or letting it hide inside conditional branches, you draw it as a statechart: states, transitions, events, guards, and actions on one canvas. The editor renders the graph and the underlying configuration side by side, so changing the diagram updates the source and vice versa. Stately's positioning is that a code diff shows which lines moved, but not that a refund path became unreachable; a statechart shows the behavior change directly.

The platform's newer focus is agentic development. Stately runs a hosted MCP server over streamable HTTP that Claude Code, Codex, Cursor, VS Code, and other MCP clients can connect to in a few commands. Through it, an agent can scan a repository, extract machines from source, validate a machine, convert between XState, SCXML, Mermaid, and D2, diff two versions of a machine, enumerate paths, simulate events, and render diagrams. There is also a CLI (npx statelyai) for scanning, pushing, pulling, and diffing, and the diff command can be wired into CI as a gate that fails a build when machine semantics change.

Beyond individual machines, Stately models whole systems: architecture views connect services, actors, and machines from imported C4, Structurizr, D2, or Mermaid diagrams. The inspector attaches to a running app and streams live state, context, events, and actor activity so you can see what the software is actually doing. The product is used by product engineers, platform teams, and QA and testing groups who need shared, reviewable models of complex logic.

## Pricing & Plans

Stately has a generous free tier: unlimited public projects and machines, browsing and simulating public machines, export to JavaScript and TypeScript, and 200 AI credits per month. Pro is $39/month monthly or $33/month billed annually and adds unlimited private projects, codebase sync via GitHub, CLI, and SDK, test path generation, lock and version history, live simulation, and 1,000 AI credits. Team is $199/month monthly or $167/month billed annually for up to 10 members, shared projects, admin roles, and 4,000 shared credits. Enterprise adds custom hosting, SSO, audit logs, embedding, custom integrations, and custom export formats with quoted pricing.

## Key Features & Capabilities

- **Visual statechart editor:** Model states, transitions, events, and parallel regions in a drag-and-drop canvas that renders as clean, readable statecharts humans can review at a glance.
- **Simulation and inspection:** Attach to a running app to watch active states, emitted events, and actors as they happen, with live simulation mode on paid plans.
- **MCP server for coding agents:** A hosted MCP server plus CLI lets Claude Code, Codex, Cursor, and VS Code scan repos, map behavior, diff machines, and apply structured edits.
- **Code generation and format conversion:** Move between XState, SCXML, Mermaid, and D2, or let the tool generate machine code directly into your JavaScript and TypeScript project.
- **Diff, versioning, and CI gates:** Use GitHub, CLI, or SDK sync plus a diff command that can fail CI builds when machine semantics change unexpectedly.
- **Architecture and system modeling:** Import C4, Structurizr, D2, or Mermaid diagrams to map how services, actors, and machines connect across a whole system.

## Primary Use Cases

- **Model UI and app flows (Product engineer):** Model onboarding flows, checkout, authentication, or async jobs as statecharts so edge cases and unreachable states surface before release.
- **Review AI-generated code changes (Platform team lead):** Use the MCP server and CLI so coding agents map repositories, extract machines from source, and propose edits reviewers can approve as graphs rather than line diffs.
- **Generate and gate test paths (QA engineer):** Extract machines from source, generate test paths from the model, and fail CI builds when a change breaks machine semantics.
- **Design distributed and actor-based systems (Backend developer):** Represent asynchronous actors that run in parallel and communicate with each other, which is hard to express clearly with traditional flowcharts.

## Strengths

- Turns abstract application logic into diagrams teammates and reviewers can actually read
- First-class MCP support lets Claude Code, Codex, Cursor, and VS Code reason about your real state machines
- Free tier is genuinely usable for public projects, simulation, and exports
- Round-trips between the visual diagram and XState source instead of being a one-way drawing tool
- Diff and CI gate features catch behavior regressions that a normal code diff hides

## Limitations

- The underlying statechart/XState concepts have a real learning curve for newcomers
- Most advanced collaboration features are tied to per-seat Team pricing, which adds up quickly
- AI credits are metered, so heavy generation usage on the free tier runs out fast
- Some capabilities (custom hosting, SSO, audit logs) are Enterprise-only

## Frequently Asked Questions

### What is Stately?
It is a visual editor and modeling platform for state machines, statecharts, and workflows. You draw behavior as a graph, simulate it, generate code, and connect the model to your codebase so both humans and AI coding agents can reason about it.

### Can I use Stately for free?
Yes. The editor is browser based, so you can design, browse, and simulate public machines without installing anything. A free plan covers public projects and exports to JavaScript and TypeScript.

### How much does Stately cost?
Free is $0 with public projects, simulation, and 200 AI credits per month. Pro is $39/month monthly, or $33/month billed annually. Team is $199/month monthly, or $167/month billed annually for up to 10 members. Enterprise pricing is quoted on request.

### How does the MCP server work with coding agents?
Stately connects to Claude Code, Codex, Cursor, VS Code, and any MCP-compatible client over a hosted streamable HTTP endpoint at mcp.stately.ai. Agents can validate machines, convert formats, diff behavior between versions, and extract machines from source code.

### Can I export my state machines as code?
Yes. You can export machines to JavaScript and TypeScript, and Pro adds codebase sync via GitHub, the CLI, and the SDK. XState is supported but not required in your application code.

### Is Stately an AI chatbot or image generator?
Stately is a general-purpose modeling and reasoning tool for application logic, UI flows, backend workflows, and architecture. It is not a dedicated chatbot or image generator.

### What is Stately's monthly traffic and growth trend?
Stately currently receives 25.49K monthly visits, with a month-over-month traffic change of -19.57K (-43.4% growth rate). Its primary source market is United Kingdom (38.9% share), including 6.93K direct visits/mo and — organic search visits/mo.
