Quite simply: starting from nothing, starting from zero. In tech, you often hear « building an application from scratch ». It means designing and developing an application from a blank page, rather than building on top of the latest version of the app or a similar template.
The upside of starting from zero is more freedom in design and only building what is strictly necessary, without dragging along useless apps, plug-ins or patches. The downside: it obviously requires more time and more skill.
