# fx is now available in T3 Code

By Steven Van · 2026-10-28

T3 Code users can add fx as a provider on web, desktop and mobile, with Supervised and Auto modes and their existing fx models and skills.

You can now run fx, [Vercel](<https://creatorstoolbox.com/tools/vercel>)'s open-source coding agent harness, inside T3 Code on web, desktop and mobile. T3 Code is an open-source control plane for coding agents, and it lets users add agents like fx as providers for their coding sessions, as [Vercel's changelog](<https://vercel.com/changelog/fx-is-now-available-in-t3-code>) describes.

## What the fx provider supports

The built-in fx provider works in both Supervised and Auto modes. It also carries over the models and skills already configured in fx.

## Setting it up

- Install fx and set up a model provider.

- Download T3 Code.

- Add fx from Settings &gt; Providers &gt; Add provider.
