In Short
Custom Fields: Core is an Odoo 19 Extra Tools app. The technical core to add new fields for Odoo documents without any special knowledge.
Standard Odoo fields rarely match every business process, and waiting on developers for every new column slows the team down. Custom Fields: Core is the technical engine that lets document-specific extensions add real Odoo fields — without Studio and without writing code.
Adding a field is really simple: create it, pick its type and placement, and the app generates a true ir.model.fields column plus the form views. Supports text, numbers, dropdowns, checkboxes, dates, files, and many2one references; fields stay searchable, importable, and exportable. The design is migration-safe: on a new major Odoo version, restart with the latest code and update any field to refresh the views — no rebuild required. This core is not useful on its own — install a document-specific extension (Contacts, Opportunities, Products, Projects, Tasks, and more).
Perfect for

One shared engine powers Contacts, CRM, Products, Projects, Tasks, and other extensions.
Migration-safe upgrades
Keep custom columns across major Odoo versions: restart with the latest code, refresh a field, and continue — no rebuild.
