Caspian provides developers with an SDK to equip their AI agents with seamless communication across popular messaging channels including WhatsApp, Slack, iMessage, Telegram, and email. Agents automatically select the optimal channel based on urgency, timing, and user relationship. Each agent receives its own dedicated phone number, inbox, handle, and conversation history. It supports various agent use cases such as support, sales, scheduling, and internal tools through a single integration that automatically expands to new platforms.
In the AI & ML space, Caspian takes a focused approach. It focuses on enabling AI agents to communicate with humans across multiple messaging platforms without building separate integrations for each. Caspian is a B2B product aimed at AI agent developers. A free plan is available. It ships for the web and the command line.
Behind Caspian is TryCaspian, and it first shipped in 2026. Development happens publicly on GitHub with 220 stars and 67 commits in the last 90 days. Key capabilities include multi-channel routing, agent identity management, and unified inbox. It exposes integrations via a public API.
