Erxes

Open-source Experience Operating System (XOS) that unifies marketing, sales, operations and support in one self-hostable platform, positioned as a replacement for HubSpot, Zendesk, Linear and Wix. The machine surface is a GraphQL Federation API served by an Apollo Router gateway — there is no REST API and no OpenAPI — covering contacts, companies, products, tags, documents, brands, organization structure, team members and automations in the core subgraph, plus sales, frontline (inbox/tickets), operation (projects/tasks/cycles) and block plugin subgraphs. Authentication is OAuth 2.0 Device Authorization Grant with per-tenant clients and a documented 34-scope vocabulary. erxes ships the Community Edition under AGPL-3.0 alongside a proprietary Enterprise Edition, publishes its own agent plugin and agent skills, and releases roughly once per merge day.

Erxes publishes 1 API on the APIs.io network. Tagged areas include GraphQL, CRM, Customer Experience, Open-Source, and Marketing Automation.

The Erxes catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Erxes’ developer surface includes documentation, getting-started guide, API reference, engineering blog, support, pricing, signup flow, and 34 more developer resources.
