v0 turns every idea into a pull request. MakeThemCode lets you decide which ones need one.
Both let people who are not developers change an existing repository from a chat. The difference is how much the developer controls, and where the app runs.
Side by side
Starting point
v0:A new app, or a GitHub repository imported into a v0 chat.
MakeThemCode:Your GitHub repository, cloned on its own branch for each session.
Every change
v0:Goes to a working branch, then a pull request.
MakeThemCode:Committed straight to your branch, or a pull request on the paths you flagged.
Developer rules
v0:GitHub's own branch protections.
MakeThemCode:Forbidden files, paths that require a review, monthly spending limits per member.
Preview
v0:A Vercel preview deployment per branch.
MakeThemCode:Your own dev server, running live in a cloud sandbox next to the chat.
Pricing
v0:Subscription plans with monthly credits.
MakeThemCode:Pay as you go, no subscription.
Which one you actually want
These tools do not compete as often as it looks. They answer different moments.
Point it at the repo you already ship.
Connect a GitHub repository, set the files nobody may touch, and send your first invitation.
