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:

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
