xNet

Decentralized data infrastructure and application. Local-first, P2P-synced, user-owned data.

xNet is both the underlying infrastructure and the user-facing app — one product, one brand. It starts with documents and databases, then expands via plugins to support ERP, MCP integrations, and more.

Try It Now

Try the demo at xnet.fyi/app — no signup required, just use your device's passkey (Touch ID, Face ID, Windows Hello).

Demo mode: Your data is stored locally in your browser (local-first). Encrypted backups sync to our demo hub with a 10MB quota and expire after 24 hours of inactivity. For reliable cross-device sync and permanent backups, download the desktop app.

Getting Started

# Install dependencies
pnpm install

# Run the root Storybook catalog and workbenches
pnpm dev:stories

# Build the static Storybook site
pnpm build:stories

# Build all packages
pnpm build

# Run unit tests (~2400 tests across 148 test files)
pnpm test

# Run integration tests (real browser via Playwright)
pnpm --filter @xnetjs/integration-tests test

# Type check
pnpm typecheck

# Lint
pnpm lint

Component Development

xNet now ships a root Storybook workspace for isolated component development across shared UI and app-facing surfaces.

• Run pnpm dev:stories from the repo root to launch Storybook on http://127.0.0.1:6006.
• Use pnpm build:stories to produce the static catalog and pnpm test:stories to run Storybook tests against a running server.
• In Electron dev builds, open the embedded Storybook surface from Open Stories in the system menu or command palette.
• In Web dev builds, open the embedded route at /stories.

Current Storybook coverage includes:

• @xnetjs/ui primitives, composed components, comments, settings, and devtools catalogs
• @xnetjs/editor rich collaborative editor workbench
• @xnetjs/views database surface workbench
• @xnetjs/canvas canvas workbench
• selected Electron and Web renderer stories

Data Model

Everything is a Node (universal container). A Schema defines what the Node is.

import { defineSchema, text, number, select } from '@xnetjs/data'

const InvoiceSchema = defineSchema({
  name: 'Invoice',
  namespace: 'xnet://myapp/',
  document: 'yjs',
  properties: {
    title: text({ required: true }),
    amount: number(),
    status: select({
      options: [
        { id: 'draft', name: 'Draft' },
        { id: 'sent', name: 'Sent' },
        { id: 'paid', name: 'Paid' }
      ] as const
    })
  }
})

Sync Strategies

Data Type	Sync Mechanism	Conflict Resolution
Rich text (documents)	Yjs CRDT	Character-level merge
Structured data (nodes)	NodeStore + Lamport	Field-level LWW

Identity, Roles, and Authorization

xNet schemas can include an authorization block that maps identity (DID) to roles and actions.

• Identity: Every node has createdBy: did:key:...
• Roles: Resolved from creator, person properties, or related nodes
• Actions: Canonical actions are read, write, delete, share, admin
• Delegation: Grants (UCAN-backed) allow secure permission delegation

const ProjectDocSchema = defineSchema({
  name: 'ProjectDoc',
  namespace: 'xnet://myapp/',
  document: 'yjs',
  properties: {
    title: text({ required: true }),
    owner: person(),
    editors: person(),
    project: relation({ schema: 'xnet://myapp/Project@1.0.0' })
  },
  authorization: {
    roles: {
      owner: role.creator(),
      editor: role.property('editors'),
      projectAdmin: role.relation('project', 'admin')
    },
    actions: {
      read: allow('owner', 'editor', 'projectAdmin'),
      write: allow('owner', 'editor', 'projectAdmin'),
      delete: allow('owner', 'projectAdmin'),
      share: allow('owner', 'projectAdmin'),
      admin: allow('projectAdmin')
    },
    publicProps: ['title']
  }
})

Authorization builders (allow, role, etc.) come from the data auth module and compile to schema-level policy metadata.

Primary React Hooks

import { useQuery, useMutate, useNode, useIdentity, useCan, useGrants } from '@xnetjs/react'

// Structured data
function TaskList() {
  const { data: tasks, loading } = useQuery(TaskSchema)
  const { create, update, remove } = useMutate()

  return (
    <ul>
      {tasks.map((task) => (
        <li key={task.id}>{task.title}</li>
      ))}
      <button onClick={() => create(TaskSchema, { title: 'New', status: 'todo' })}>Add</button>
    </ul>
  )
}

// Rich text with Yjs CRDT
function PageEditor({ nodeId }: { nodeId: string }) {
  const { data: page, doc, syncStatus, peerCount } = useNode(PageSchema, nodeId)
  if (!doc) return null
  return <RichTextEditor ydoc={doc} />
}

// Identity + permissions
function SharingPanel({ nodeId }: { nodeId: string }) {
  const { did } = useIdentity()
  const { allowed: canShare } = useCan(nodeId, 'share')
  const { grant } = useGrants(nodeId)

  return (
    <button
      disabled={!canShare}
      onClick={() =>
        canShare && grant({ to: 'did:key:z6MkRecipient...', actions: ['read', 'write'] })
      }
    >
      Share as {did.slice(0, 16)}...
    </button>
  )
}

Build	Turborepo, tsup, Vite
Testing	Vitest, Playwright (browser mode)

Roadmap Status (Mar 2026)

Phase	Focus	Status
Phase 1	Product reliability (navigation, search, daily-driver polish)	In progress
Phase 2	Collaboration + trust (invites, sharing UX, presence reliability)	Next
Phase 3	Platform clarity (package lifecycle, API simplification, multi-hub integration)	Planned

See docs/ROADMAP.md for the detailed execution plan.
