fx
A Vercel-built product related to coding agents that provides cloud-side durability.
Core Facts
Timeline (last 90 days)
The Agents supported by this plugin include fx, Codex, Claude Code, OpenCode, and Pi.
The open-source coding agent tool fx has been officially integrated into T3 Code, and users can use it on web, desktop, and mobile.
The integration path is: first install fx and set up a model provider, then download T3 Code and add fx under "Providers > Add provider" in settings.
When integrating fx in T3 Code, the models and skills the user already uses in fx are compatible, requiring no reconfiguration.
T3 Code provides built-in provider support for fx, including two modes: Supervised and Auto.
T3 Code is an open-source control plane for coding agents that allows developers to add agents such as fx as providers for coding sessions.
The refactor is driven by libfx (the TypeScript library of fx).
The adapters covered by HarnessAgent image input include Claude Code, Cline, Codex, Cursor, Deep Agents, fx, GitHub Copilot, Grok Build, OpenCode, and Pi.
Vercel has launched durable-harness, a set of adapters and tools that let third-party coding agent frameworks such as Pi, OpenCode, Codex and Claude Code gain durability (resistance to crashes and function timeouts) in the cloud.
Token Pass can be used directly with coding agent tools such as fx, Command Code, and Pi, or you can build a custom personal agent through the AI SDK.

The cold start time of native binary files is typically in the millisecond range, whereas the cold start latency of Python- or Node.js-based tools is often in the range of hundreds of milliseconds to several seconds.

50%Unverifiedfx can be embedded into a user's own agent infrastructure, rather than being merely a standalone command-line tool.
50%Unverifiedfx supports connecting to both local models and cloud-based models simultaneously and adopts a model-agnostic architecture.
