local development is (or local dev, local dev setup) the practice of having a version of your site on your local machine like a laptop that you can use for development purposes, even when offline.
In 2015, Google applied to register the .dev TLD. In their "mission/purpose" description of the application, they stated:
The mission of this gTLD, .dev, is to provide a dedicated domain space in which Google can enact second-level domains specific to its projects in development. Specifically, the new gTLD will provide Google with greater ability to create a custom portal for employees to manage products and services in development.
In mid-2018, Google finally published the first public website at a domain on this gTLD, https://datatransferproject.dev
- Google, Our Patron Saint of the Closed Web
- Thanks a lot, Google, for snatching .dev for yourself. It's not like the rest of us wanted it
- Use a .dev domain? Not anymore.
It is recommended to use one of the IANA reserved gTLDs for development, as these are guaranteed to not be registered by any company in the future.
