Odoo S.A. · CRM & sales clouds
The Odoo Apps Store is the module marketplace for Odoo, the open-source suite whose CRM, Sales, Invoicing, Inventory, and dozens of other apps share one data model. It is one of the largest business-software module ecosystems, built by the Odoo community (notably the OCA), independent developers, and Odoo partners who publish both free and paid modules and themes for every supported Odoo version.
Modules are Python/XML packages tied to a Git repository: developers register a repo, Odoo scans it, and the module is published against a chosen Odoo version. External integrations authenticate primarily via API keys passed as the password in XML-RPC or JSON-RPC calls or through an X-Api-Key header, with session and database-uid auth as alternatives, and Odoo 19 adding OAuth2 provider capability. Publishing is deliberately open — Odoo does not pre-review every module and instead removes listings reactively when users report abuse. Choose the Odoo Apps Store when extending the Odoo ERP/CRM stack itself with vertical modules, localizations, or connectors for self-hosted and Odoo-cloud customers.
