Edit/save content locally

Is it possible to store content locally when developing? I find it cumbersome that anytime I go to test things on my site I end up pushing changes to GitHub or having to pull to get my content .json files up to date.

I’ve seen pushOnCommit: false for Gatsby but is there something similar for Next.js? I first set this site up in November and I feel like the documentation/api has changed a bit since then so maybe I just don’t have my next config setup correctly, right now all I have in there are my .env variables for Github.
