Build a Website From Figma With a Coding Agent

To build a website from Figma with a coding agent, give it authorized design material, a small page scope, and a testable output contract. The output is an owned codebase, not a Figma export or a published Figment page. Check the rendered page against the design at each intended width, then review semantics, links, and assets before you deploy.

This guide assumes you are implementing a design for a client or team that permits you to use it. If your task is to publish a Figma frame directly, use the Figma publishing guide. If you only need to know which HTML export routes exist, use the Figma-to-HTML guide. Here, the deliverable is code your team can maintain.

What should you collect before the agent starts?

Make a handoff folder with a short brief, approved screenshots, and assets. Name the page, its desktop and mobile frames, the intended URL, and the actions that each visible control must perform. Mark sample text that needs owner approval. If the design omits a hover state, an error message, or a mobile navigation state, mark it as a decision for the owner. Do not let the agent invent product claims or form behavior.

Confirm access first. Figma files have sharing permissions, and an owner can restrict copying and exporting for viewers. A link that opens a file does not automatically authorize you to copy its assets into a public repository. Ask for the required permission or owner-provided exports if access is restricted. Figma explains these controls in its sharing guide and copy/export restriction guide (accessed 2026-09-23).

Figma Dev Mode can help you inspect layer properties, spacing, variants, and downloadable assets. Its Code view supplies snippets for selected layers, not a complete application. It is available on paid plans with a Full or Dev seat, so the workflow must also work from approved screenshots and written values when that seat is unavailable. Figma lists PNG, JPG, SVG, and PDF as export formats in its Dev Mode guide (accessed 2026-09-23).

What is a useful design-to-code brief?

Use one page as the first acceptance target. The example below is hypothetical. It does not describe a customer project or a tested conversion.

Page: /studio/ (one landing page)
Approved source: owner-supplied desktop and mobile frames
Output: index.html, styles.css, assets/ in this repository
Desktop: content max width follows the supplied frame
Mobile: use the supplied mobile frame; do not scale down desktop
Content: copy supplied in content.md; do not invent testimonials
Behavior: logo goes home; contact link opens the existing contact URL
Constraints: no backend, checkout, analytics, or new dependencies
Done when: no horizontal scroll at 360, 390, 768, or 1440 px;
all links work; keyboard focus is visible; images have correct alt text

Give the agent the actual frame images, assets, and brief by a method your tool supports. Some tools can inspect a Figma file through a configured integration; others cannot. Do not write a prompt that assumes an all-in-one Figma MCP connection exists. If the agent cannot read the source, supply screenshots and exact measurements yourself. Keep design tokens such as colors, font family, spacing, and content width in the brief so a later reviewer can trace decisions.

How should the agent implement the page?

Ask for semantic HTML first: a header, navigation, main region, heading order, links, and buttons that match their actions. Then ask for a responsive layout using grid or flexbox, not absolute coordinates copied from the canvas. A layer at a specific x-position is a design observation; it is not a durable browser layout rule. Use exported images where needed, but keep text as text. A full-frame image with invisible links over it fails accessibility and maintenance tests.

Ask the agent to list missing information before it writes code. For this example, it might ask whether a card is clickable as a whole or only its title. Resolve that with the owner. Then have it implement the single page and report files changed, build command, and known gaps. Review the diff before adding a second page. This is a new implementation workflow; edits to an existing codebase have their own static-site editing guide.

How do you compare the output with Figma?

Create a comparison record. For each target width, put the approved frame and a browser screenshot side by side. Record the exact width and one of three outcomes: match, acceptable interpretation, or defect. Do not require pixel identity where browser text rendering differs. Do require correct content, hierarchy, spacing intent, image crop, and behavior. Test an intermediate width as well as the supplied frames; a page can match at 390 and 1440 pixels and still break between them.

For each defect, name the element and the observed problem: "navigation overlaps the title at 768 px" is actionable; "mobile looks off" is not. Re-run the same widths after each fix. The mobile repair guide gives a failure-log method for an existing desktop-first page. MDN's responsive design guide explains why fluid layouts and media queries need browser testing (accessed 2026-09-23).

What must pass before you accept the code?

• The owner authorized the design and each exported asset.
• The repository contains editable text and named assets, not one flattened page image.
• The desktop, mobile, and intermediate screenshots have recorded results.
• Every link and control has a defined destination or behavior.
• Headings, image alternatives, labels, and keyboard focus work.
• The local build and page preview pass; unresolved decisions are documented.

You can use AI with your website to prepare a focused change brief. It produces a prompt, not code access. Figment's AI editor access page currently accepts early-access requests for editing a separate imported static copy. It does not import arbitrary local files or update this repository. It also does not transfer forms, checkout, or backend services. Keep this design-to-code project in your own repository and hosting flow.
