See where your teammates are working in real-time. Each collaborator has a unique cursor color with their name displayed.

FluxCore uses CRDT (Conflict-free Replicated Data Types) technology to ensure that all edits merge seamlessly, even when multiple people edit the same component.

// How CRDT handles simultaneous edits

// Alice changes ring radius to 10um
// Bob changes ring radius to 12um at the same time

// Traditional approach: CONFLICT! One change lost.

// FluxCore CRDT approach:
// 1. Both changes are captured with timestamps
// 2. Changes are merged using Last-Writer-Wins
// 3. Both users see the result immediately
// 4. Full history preserved for both changes

// If needed, restore any previous state:
circuit.history.restore("version_abc123")

Leave comments directly on components, connections, or any part of your design. Perfect for design reviews, feedback, and documentation.

Fine-grained permissions let you control exactly who can view, edit, or manage your designs.

// Share a design programmatically
circuit.share({
  email: "colleague@company.com",
  role: "editor",
  notify: true,
  message: "Please review the ring resonator section"
});

// Share with a team
circuit.share({
  team: "photonics-team",
  role: "viewer",
  expires: "2025-02-01"
});

// Create public link (view only)
const link = circuit.createPublicLink({
  allowExport: false,
  password: "optional-password",
  expires: "7d"
});

Every change is automatically saved and tracked. Browse through your design's complete history, compare versions, and restore any previous state.
