​
Step by step setup

1

Sign in to OpenSync

Go to opensync.dev and sign in with GitHub, Google, or email. Your account is created automatically on first sign in.
2

Generate an API key

Open Settings from the sidebar and click Generate API Key. Copy the key. It starts with osk_ and is shown only once.
3

Install a sync plugin

Install the plugin for your tool globally with npm:
npm install -g opencode-sync-plugin   # For OpenCode
npm install -g claude-code-sync       # For Claude Code
npm install -g codex-sync             # For Codex CLI
npm install -g cursor-opensync-plugin # For Cursor
4

Run the login command

Each plugin has a login command that stores your credentials locally:
opencode-sync login
When prompted, enter:
  • Convex URL: https://polished-penguin-622.convex.cloud
  • API Key: The key you copied from Settings
5

Start coding

Open your coding tool and start a session. The plugin picks up new sessions automatically and syncs them to your dashboard. You should see your first session appear within seconds.
The hosted version uses https://polished-penguin-622.convex.cloud as the Convex URL. All plugins need this URL during login.

​
Verify it works

After logging in, run the status command to confirm the connection: 
opencode-sync status
You should see output like: 
Connected: true
Convex URL: https://polished-penguin-622.convex.cloud
Sessions synced: 0
Then start a coding session. Open your dashboard at opensync.dev and the session should appear in the Sessions view.

​
What gets synced

Each session includes:
  • Title auto-generated from the first user message
  • All messages with role labels (user, assistant, system, tool)
  • Token counts per message and per session (prompt and completion tokens)
  • Cost estimate based on published model pricing
  • Model name and provider
  • Project path (if available from the tool)
  • Timestamps for session creation and last update
Message parts are preserved, including text content, tool calls, and code blocks.

​
Data and privacy

  • Sessions are stored in your personal Convex database partition
  • No data is shared between accounts
  • WorkOS handles authentication with enterprise-grade security
  • You can delete any session or your entire account at any time
  • Self-hosting is available if you need full control over the infrastructure
