About

Customermates has an open-source CRM core for small teams, with contacts, organizations, deals, services, tasks and custom fields. It provides REST APIs, webhooks and authenticated MCP tools so compatible external AI clients and automation workflows can work with CRM records. The core can be self-hosted with Docker Compose under AGPL-3.0-only. Self-hosted installations use external AI clients through MCP. The managed cloud service also offers Mate, a cloud-only AI assistant, and a separately licensed unified inbox for supported email and social channels on eligible plans. The CRM core, hosted assistant and enterprise messaging have distinct licensing and availability conditions. Public source code and documentation explain the deployment options and supported integrations.

About

Mercur is an open-source, headless marketplace platform for retailers adding third-party sellers and organizations building B2B, B2C, or hybrid multi-vendor marketplaces. Built on Medusa, it combines marketplace services and APIs with an operator admin console, vendor management tools, and storefront components. Teams can manage seller accounts, product catalogs and offers, commissions, split orders, inventory, shipping, returns, promotions, and seller payouts. Developers can adapt workflows and storefronts through a TypeScript-based, modular architecture. The MIT-licensed core can be self-hosted on cloud, on-premises, or air-gapped infrastructure. A separately licensed Enterprise edition adds modules for compliance, finance, integrations, operational controls, and support for production deployments.

Pros & Cons from Real Users

Pros

  • Easy setup, intuitive workflow and n8n integration is great for automations. Very affordable in comparison to other CRMs

Cons

  • No phone support and some “advanced” stuff requires automations. No problem for me but maybe for other people.
