Integrations Overview
Connect Kantos with your favorite tools.
Kantos connects to the tools you already use: your AI assistant, your messaging apps, your calendar, payments and your website. For anything else, there's an API, webhooks and an MCP server.

What Kantos runs on
Kantos itself uses SendGrid to deliver email, Stripe to bill your subscription and Supabase to store your data. These aren't integrations you set up, but a few of their settings are yours: your sending domain, payments for bookings, and auth emails for your own Supabase project. Native integrations explains each one.
