What erxes is
erxes (Mongolian for "galaxy") is an open-source platform that puts customer service, sales, marketing and operations in one self-hosted system. It positions itself as an alternative to HubSpot, Zendesk, Intercom and Linear, and says 25,000+ organizations use it. The source is on GitHub (about 4,000 stars, TypeScript).
How it is built
- Core plus plugins. The core ships the inbox, contacts, products, segments, automation and documents. Frontline, Operation, Sales, Content, Accounting, Team and Finance are plugins you add from a marketplace.
- Backend. An Nx monorepo of Node.js and TypeScript microservices: GraphQL Federation behind an Apollo Router gateway, tRPC between services, MongoDB, Redis and BullMQ.
- Frontend. React micro-frontends joined with Module Federation, built with Rspack and Tailwind CSS.
- AI. Agents connect through MCP, a CLI or the REST API, and the automation builder has native AI steps.
The product surfaces
The omnichannel team inbox with a customer 360 sidebar, the sales pipeline board with forecasting, and the visual automation builder. The screenshots are from the public erxes.io site and belong to erxes.
