See the logic
before it ships.

Design statecharts on a canvas built for their real complexity. Inspect every transition, validate the structure, and leave with portable XState-compatible code.

  • XState v5 compatible
  • Browser-based workspace
  • Portable machine artifacts

Designed for the hard part

A precise view of
behavior in motion.

State machines become difficult at the seams: nested states, competing branches, eventless transitions, and targets that cross the hierarchy. XStatium makes those seams visible.

01

Model the real hierarchy

Compose atomic, compound, parallel, and final states without flattening away the structure that matters.

02

Catch structural mistakes

Surface unreachable states, dead ends, invalid targets, and unsafe conditional branch ordering before implementation.

03

Inspect every transition

Edit events, guarded branches, always transitions, actions, and metadata from one contextual inspector.

04

Keep the artifact portable

Import and export validated machine JSON, or generate clean XState v5-compatible TypeScript whenever you are ready.

From idea to implementation

One artifact.
Three clear moves.

  1. 01

    Draw the behavior

    Create states, nest the hierarchy, and drag to connect transitions. Auto-layout keeps the canvas legible as the model grows.

  2. 02

    Interrogate the edges

    Add guards and actions, order conditional branches, inspect context, and run structural validation against the canonical machine.

  3. 03

    Take it with you

    Export the machine as validated JSON or XState v5-compatible TypeScript. The design remains yours, with no proprietary runtime.
