Is there a Figma equivalent for AI-generated code?

Vessel is the closest equivalent built for the AI-native era. Where Figma is a workspace for design files, Vessel is a workspace for the AI-generated code itself — render, inspect, comment, send the fix back to the agent.

Different artifacts, different workspaces

Figma was built around the premise that the designer's artifact is a vector file and the engineer's artifact is hand-written code. The workflow assumes a translation step between them — handoff, redlining, rebuild. Figma optimized that translation step beautifully for fifteen years.

The premise has shifted. AI coding agents skip the translation: they produce the engineer's artifact directly. There's no design file to translate; there's a working prototype. Vessel is built around that new premise — the artifact is code, the review happens on the rendered code, the handoff goes back to the agent that wrote it.

What carries over

Three things from Figma's design language carry over directly into Vessel: (1) commenting on the canvas, not in a separate tool; (2) a left rail for navigating the project structure; (3) an inspect panel that resolves whatever the user clicked to its metadata. Vessel's metadata is the source code itself, not redline measurements.

What's different: Vessel runs the code (real DOM, real interactions), Figma renders a vector approximation. Vessel's inspect resolves pixel → source file → line; Figma's inspect resolves pixel → vector node → CSS guess. Vessel's comments anchor to the live element; Figma's anchor to the static frame.

If you're a Figma team adopting AI agents

You don't replace Figma with Vessel. Figma stays excellent for component libraries, brand systems, marketing pages where the team still designs by hand. Vessel slots in for the new workflow: when an agent ships a runnable prototype, the team reviews it in Vessel and sends the fix back to the agent.
