Project container with diagrams, brand, theme, and members Project container with diagrams, brand, theme, and members A **project** is the unit of organization in DocDiagram. Everything that should share branding, conventions, and access lives in the same project. ## What a project contains * **Diagrams** — every diagram you generate or save. * **Brand settings** — palette, fonts, and logo (see [Themes & branding](/quickstart/themes-and-branding)). * **Default theme** — light, dark, or auto. ## When to use multiple projects * **One product, one project.** Most teams need exactly one. * **Multiple products or brands.** Split into one project per product so brand tokens don't bleed across. * **Client work.** Agencies typically create one project per client. ## What's shared across projects Your account-level credit balance is shared across every project you own. So is your account-level theme preference for the editor UI itself. ## Coming soon * **Team projects** — shared editing across multiple users in your org. * **Project-level access controls** — view-only vs. edit roles. ## Next How DocDiagram charges for generation.
