kapso.aiAbout Kapso
Kapso is a WhatsApp platform for building AI agents and automated workflows on top of the WhatsApp Business API, positioned as a developer-priced alternative to the incumbent CPaaS providers. The commercial argument is direct: at 100,000 messages a month it publishes $25 against a $500 Twilio equivalent, with both figures excluding Meta's own message fees, which Kapso passes through at cost with no markup rather than reselling. What sits on top of the messaging layer is a full application platform — unlimited AI agents and workflows on every tier including free, a team inbox with unlimited seats that can be embedded into your own product, WhatsApp Flows for interactive in-chat forms, broadcasts for campaigns, and deployed serverless functions with generous monthly call allowances. Integrations reach 2,800+ apps including Gmail, HubSpot and Slack on paid tiers. Developer ergonomics are treated seriously: there is a CLI, an MCP server and Skills so you can build with Claude, Codex or Cursor directly, plus an in-app Kapso Agent for building and debugging, unlimited API requests and full logging of API calls, messages, webhooks, functions and workflows. The Platform tier targets agencies and software vendors specifically, adding white-labelled customer onboarding, setup links and centralised Meta billing across all your customers. Free accounts get 2,000 messages a month, a pre-verified US number and $2 in credit.
