Odoo
A modular, open-source business suite from Belgium covering CRM, accounting, inventory, HR, and more. Self-host the community edition or use Odoo Online.
Quick facts
The Community edition covers CRM, accounting, inventory and more as genuinely free, self-hostable software, and modules snap together so you only run what you actually need.
The free Community edition lacks some features that push businesses toward the paid Enterprise tier, and heavily customised deployments can get complex to maintain.
Why does it score 85?
Incorporated in Grand-Rosière, Belgium – a full EU member state.
Founder Fabien Pinckaers remains the largest shareholder with effective control, though outside investors including Sequoia and Alphabet's CapitalG hold minority stakes.
Odoo runs its own infrastructure in Belgium rather than a third-party cloud.
The Community edition is open source (LGPL) and self-hostable, while the Enterprise edition stays proprietary, so it's only partially open source overall.
