EspoCRM Alternative: Customermates and EspoCRM Compared

Q: Is Customermates open source like EspoCRM?

Yes. First-party code outside the ee/ directory is AGPL-3.0-only; code in ee/ uses a separate commercial licence, except client material that Section 6 of that licence keeps under the AGPL. The self-hosted edition is the open-source core with the Starter feature set.

EspoCRM and Customermates are both AGPL open-source CRMs you can self-host. They differ in stack, in how features are packaged, in messaging channels and in how AI clients work with them. This comparison shows where each fits, based on EspoCRM's official pages as of 27 September 2026.

EspoCRM is a long-standing open-source CRM written in PHP. Since version 8.1 in January 2024 it is licensed under the AGPL-3.0, and it runs on your own server or on EspoCRM Cloud. Customermates is a younger open-source CRM with an AGPL core, a unified inbox for email and chat channels, and a built-in MCP server for AI clients. Both are serious options; they suit different teams.

Why teams look for an EspoCRM alternative

EspoCRM is flexible and mature. Teams that look elsewhere usually name one of these reasons:

Extensions add up. Reports, workflows and BPM come with the Advanced Pack, Gmail and Outlook sync with separate integration extensions, and AI features with the Intelligence extension. On a self-hosted installation, each is a yearly licence per instance.
Messaging beyond email. EspoCRM handles email well, but WhatsApp, LinkedIn, Instagram or Telegram conversations are not part of the core product.
AI clients. EspoCRM's AI features live in its Intelligence extension. There is no official MCP server; the MCP servers that exist are community projects.
Stack preference. Some teams prefer a TypeScript and PostgreSQL stack over PHP.

Where EspoCRM is the better fit

You need custom entity types. EspoCRM's entity manager lets you add new record types; Customermates has a fixed set of five record families extended with custom fields.
You send campaigns from the CRM. EspoCRM includes mass email and campaigns. Customermates messaging is one-to-one by design; there are no bulk sends.
You want deep BPM. The Advanced Pack brings business process management that Customermates does not attempt.
Your team runs PHP applications and wants the CRM on the same stack.

Where Customermates is the better fit

Conversations across channels. On Customermates Cloud from Pro, email (Gmail, Outlook, IMAP), LinkedIn, WhatsApp, Instagram and Telegram arrive in one unified inbox, linked to contacts.
AI clients that operate the CRM. Claude, ChatGPT, Cursor and other MCP clients connect to the built-in MCP server on every plan and every installation, with the permissions of the connected user. On Customermates Cloud, the Mate assistant works in the app and asks for a fresh approval before destructive actions and sends.
No extension licences. The self-hosted edition is the open-source core with the Starter feature set; there is nothing extra to license per instance. The inbox and Mate are cloud-only.
Monthly billing from €12 per user, without a minimum user count.

Self-hosting compared

Both products can run on your infrastructure. EspoCRM publishes an installer and a Docker image and supports MySQL, MariaDB or PostgreSQL. Customermates ships a Docker Compose file with two services: the application and PostgreSQL 16. In both cases your team owns updates, backups, TLS and monitoring. The difference is what the self-hosted edition includes: EspoCRM's core plus any extensions you license, or the Customermates core with REST, webhooks and MCP. See the open-source CRM guide for a licence-first checklist.

Migrating from EspoCRM

Export accounts, contacts and opportunities from EspoCRM to spreadsheets.

Import each record type as an XLSX workbook (organizations first, then contacts, then deals), or move data through the REST API.
Rebuild stages as the deal-stage options and assign probabilities.
Connect your mailboxes and chat channels on Pro and link conversations to contacts.
