Replace the whole suite

HubSpot covers several areas. No single open-source tool replaces all of it, but a combination can. The first tool in each part is our suggestion; the others are alternatives.

The HubSpot suite with several tools

  1. CRM and sales (Sales Hub)Twenty or EspoCRM, Frappe CRM
  2. Marketing automation and email (Marketing Hub)Mautic or Dittofeed, listmonk
  3. Customer service, chat and tickets (Service Hub)Chatwoot or Zammad, FreeScout
  4. Website and content (CMS Hub)Ghost or WordPress, Payload, Strapi

What's missing: The tools don't share one contact database. You need to connect them through their APIs or an automation tool, and reporting across the whole customer journey has to be built separately. Built-in AI features, quotes and payments are not included.

Everything in one system

  1. CRM, marketing, customer service and website as modules in one systemOdoo Community

What's missing: Only Odoo Community is open source (LGPL-3.0). Several modules, including parts of marketing and customer service, are only in the proprietary Enterprise edition. Check which modules you need.
