Odoo 18 and 19 represent the peak of modular ERP, and Frappe plus ERPNext 15 has established itself as a Python-based all-in-one ERP. SuiteCRM, EspoCRM, Vtiger, Mautic, and CiviCRM divide the sales, marketing, and non-profit domains among themselves, while Twenty HQ, a Y Combinator graduate, has emerged as the modern open source CRM. This piece consolidates 18+ open source tools and a SaaS comparison set (Salesforce, HubSpot, NetSuite, Microsoft Dynamics, SAP S/4HANA, Workday) onto a single page, and also covers Korean (Duzon, Younglimwon, Wisetech) and Japanese (OBC Bugyo, Yayoi, freee, Money Forward) local ERP/CRM. Self-host vs SaaS, migration patterns, AI in CRM, and reporting with Metabase/Superset — all in one place.
