Vessel

Vessel is a developer-first embedded integrations platform that enables product teams to add native integrations to their applications. It provides unified API abstractions, actions APIs, and passthrough APIs to connect with CRM, sales engagement, marketing automation, chat, and dialer tools while managing authentication, rate limits, and data normalization. The platform supports OAuth and API-key authentication via a drop-in React UI component (Vessel Link), with two API surfaces: api.vessel.dev for the newer GTM integrations platform and api.vessel.land for the CRM-focused platform.
