Why we included this project

Anyone who has built a bot that talks to real users knows the chore of wiring it into Slack, Telegram, email, Discord, or WhatsApp, since each channel brings its own adapter code, auth quirks, and threading edge cases. Caspian collapses that into a single Python or TypeScript SDK where one handler reaches every channel, with declarative routing, threading, and webhook verification handled for you. You can run it through a hosted gateway your process polls, or self-host it with your own webhook routes and tokens, so managed and on-prem setups both work. The payoff is that choosing a reply channel becomes a decision the agent itself can make, whether to send a quick Telegram ping or a fuller email, instead of hardcoded plumbing. If you currently keep a separate bot per platform, or want one agent identity that carries across the channels your users already live in, this is worth a look.
