My main use case for v0 involves building small MVPs for clients or POCs, or mostly doing the front-end work. If I have to connect with any Supabase database, I will use v0 for that.
I have worked on a project where I had to display military documents for an aerospace company, allowing them to search the documents and see all the relevant revisions. I created all of it from start to finish in v0, deployed it on Vercel via v0, and pushed the code to GitHub with the help of v0.
