# Deploy and Host ContextMate on Railway

  ContextMate is a zero-knowledge encrypted sync service for AI agent context —
  memories, skills, rules, and identity files. Your passphrase never leaves your
   device; the server only stores encrypted blobs.

  ## About Hosting ContextMate

  This template deploys the ContextMate server with persistent storage.
  Everything works out of the box — no configuration required. A JWT signing
  secret is auto-generated on first boot and persisted to disk.

  After deploying, point your CLI at your new server:

  ```bash
  npm i -g contextmate
  contextmate setup
```
Enter your Railway server URL when prompted

  ## Why Deploy

  - Own your data — Run the sync server on your own infrastructure instead of
  relying on a shared hosted service.
  - Zero-knowledge encryption — AES-256-GCM with Argon2id key derivation. The
  server never sees your plaintext data.
  - Zero config — JWT secret auto-generates, SQLite database initializes on
  first request. Just deploy and go.
  - Earn from Railway — Template creators earn a share of usage revenue from
  deployments.

## Common Use Cases

  - Self-hosting for teams that require data sovereignty or compliance
  - Syncing AI agent context (memories, skills, rules) across multiple devices
  - Real-time sync between Claude Code, OpenClaw, Cursor, and other AI agents
  via WebSocket
  - Running a private MCP-compatible context server for your organization
