The Claude Code background agent for Linear, Slack, Github, GitLab etc. you deploy anywhere. Supports Codex, Cursor, Gemini, and Opencode harnesses too.

Cyrus

Note: Cyrus is a BYOK platform (bring your keys / subscriptions) for tokens.

Getting Started

End-to-End Self-Hosted (Community)

Zero cost option — host everything yourself with your own Linear OAuth app, GitHub App, and Slack App. An AI-guided setup skill handles the entire onboarding: installing dependencies, configuring auth, creating integration apps, and connecting repositories — so you don't have to follow a manual guide.

npx skills add ceedaragents/cyrus -g

Then in any AI coding agent (Claude Code, Codex, Cursor, etc.):

/cyrus-setup

Or follow the manual setup guide if you prefer.

Pro & Team Plans

Configure Cyrus through the dashboard at app.atcyrus.com.

For paid self-hosted deployments

It is called 'self-hosted' because it uses a machine you control as the agent runtime. Networking layer and integrations are provided by the Cyrus cloud provider.

# Install Cyrus
npm install -g cyrus-ai

# Authenticate with your token (provided during onboarding)
cyrus auth

For Cyrus to create pull requests or merge requests, configure Git and your hosting CLI. See Git & GitHub Setup or Git & GitLab Setup.

Keep Cyrus running as a persistent process:

tmux: tmux new -s cyrus then run cyrus (Ctrl+B, D to detach)
pm2: pm2 start cyrus --name cyrus
systemd: See Running as a Service

For cloud-hosted deployments

No installation required. Everything is managed through app.atcyrus.com.
