Netlify has introduced Netlify Dev, a feature that allows developers to spin up a local dev environment via the Netlify CLI, giving them access to Netlify features like redirects, functions, and env variables on their local machine. This enables quick iteration and testing of frontend and serverless functions before deploying to production. The Netlify CLI also offers a faster deploy process with a "deploy --open" command, which allows for quicker turnarounds and easier sharing of preview URLs with teams. However, it's recommended to use this feature in moderation due to potential risks of deploying untested code to production.
