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

OpenGMB helps small businesses and marketing agencies manage Google Business Profiles. It uses Google’s official Business Profile API to bring reviews and replies, scheduled posts, profile edits, health checks, performance reports, and client approvals into one workspace. Teams can assign reviews, add internal notes, make bulk edits across locations, and share branded reports or a client portal. Configurable rules check replies, posts, and profile edits before publication; posts and profile edits require approval, while eligible four- and five-star review replies can be auto-approved when enabled. OpenGMB includes an MCP server and REST API for compatible clients and agents using permissioned tokens. The MIT-licensed community edition can be self-hosted with Docker. The hosted service adds teams, roles, client access, and custom domains. It also includes a Maps rank-tracking view.

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.
