The Caspian SDK is open source and provides a single identity for an agent across all communication channels. It supports over a dozen channels with a single connect call and handler, including Slack, Discord, GitHub, Telegram, email, Instagram, Messenger, X, SMS, Bluesky, and via the hosted gateway WhatsApp, iMessage, voice, and RCS. The SDK is available in Python and TypeScript, includes 131 offline tests, and offers plugins for openclaw and OpenCode.

Free channels can be connected without requiring a sign-in. The SDK is licensed under MIT for clients and AGPL for the server.
