Odoo
CRM as one module of a full business suite.
Odoo is not primarily a CRM — it is an integrated business suite where CRM sits alongside accounting, inventory, manufacturing, HR and e-commerce, all sharing one database. For a company that would otherwise buy four systems and wire them together, that integration is the entire proposition and it is a strong one. The Community Edition is LGPL-3.0 and genuinely capable; Enterprise adds modules and support for a per-user fee. Around 53k stars. The caveat is scope: adopting Odoo for CRM alone means running a great deal of software you are not using.
What it does well
- +CRM, accounting, inventory and more sharing one database
- +LGPL-3.0 Community Edition is genuinely usable, not a demo
- +Enormous module ecosystem and a large partner network
- +Replaces several systems rather than one
Where it falls short
- −Substantial to deploy and operate if you only want CRM
- −The Community/Enterprise line moves and is worth watching
- −Customisation generally needs Odoo-specific expertise
- −Upgrades between major versions are real projects
