Figma Dev Mode vs html2design: When to Use Which

The One-Line Summary

Figma Dev Mode is for reading designs. It generates CSS snippets, spacing values, and export-ready assets from Figma files that designers have already created. It assumes Figma is the source of truth.

html2design is for importing designs. It converts live HTML and CSS into native Figma layers when the source of truth is in your codebase — not in a design file. It assumes the browser is the source of truth.

If you're a developer consuming a design spec: Dev Mode. If you're bringing an existing UI into Figma for documentation or redesign: html2design.

What Figma Dev Mode Actually Does

Figma Dev Mode (available on paid plans) adds a developer-focused reading layer on top of existing Figma designs. When activated, it provides:

• CSS value extraction — Click any layer and see the computed CSS: font-size, line-height, color, border-radius, box-shadow
• Spacing and sizing annotations — Distances between elements, padding, margins
• Asset export — Download icons and images in SVG, PNG, or WebP directly from the panel
• Code Connect — Link Figma components to your actual code components so developers see the real implementation, not just CSS snippets
• Redlines and annotations — Persistent design notes tied to specific frames

Dev Mode works on designs that already exist in Figma. It is entirely about reading and interpreting those designs — you cannot use it to create Figma layers or import anything.

What html2design Actually Does

html2design is a Figma plugin that reads HTML and CSS source code and generates native Figma layers: frames, text nodes, shapes, fills, borders, and SVG vectors. You paste raw HTML into the plugin panel, click Convert, and the output appears on the Figma canvas — editable, renameable, and ready for design work.

Because it works from pasted code rather than a browser URL or extension, it handles sources that Dev Mode (and most other tools) cannot:

• Localhost and dev servers — localhost:3000, localhost:6006 (Storybook), internal staging
• Auth-gated dashboards — Copy HTML from DevTools while logged in; paste into html2design
• Any framework output — React, Vue, Angular, Svelte, Tailwind, Bootstrap — anything that renders to HTML
• Legacy codebases — Import old production UI for redesign without rebuilding from scratch

Side-by-Side Comparison

When to Use Figma Dev Mode

Dev Mode is the right tool when:

• Your design team works in Figma and you need to hand designs off to developers
• Developers need to extract exact CSS values, spacing, and typography from a spec without asking the designer
• You want to link Figma components to their production code counterparts with Code Connect
• You're building a workflow where design is the single source of truth and code follows design

When to Use html2design

html2design is the right tool when:

• You need to import an existing codebase into Figma — the UI exists in code but not in a design file
• You're doing a legacy migration and need editable Figma designs from your old UI before rebuilding
• You need to document a component library that was built without design files
• You're reverse-engineering a shipped product to align design and engineering on what's actually in production
• Your UI lives on localhost, staging, or behind authentication — Dev Mode and screenshot tools can't reach it
• You want to redesign pages and need a starting point from the current live site

The Complementary Workflow

Many teams use both tools at different stages of the product lifecycle. Here's a common pattern:

1. Kickoff: Use html2design to import your current production UI into Figma. You now have editable designs for every live component.
2. Design iteration: Designers work in Figma — adjusting, improving, creating new variants.
3. Handoff: Developers use Dev Mode to inspect the updated designs and extract CSS values, spacing, and assets.
4. Ship: Code is updated to match the new designs.
5. Re-sync: After the next sprint, use html2design again to import any ad-hoc code changes that didn't go through the design file, closing the drift loop.

This pattern is especially useful for teams inheriting a legacy codebase with no design files, or for teams where code moves faster than design and the two get out of sync.

What Figma Dev Mode Cannot Do (and html2design Can)

The most common confusion is assuming Dev Mode can import HTML or generate Figma layers from code. It cannot. Dev Mode is a viewer and extractor — it only operates on content that already exists in a Figma file.

If you have a situation where:

• A developer built a component but no Figma file was ever created
• Designers need a Figma copy of a live product page for a redesign workshop
• You want to snapshot a component's current state in Figma for documentation

Dev Mode is not the answer. html2design is.

Frequently Asked Questions

Is Figma Dev Mode a replacement for html2design?

No — they don't overlap. Dev Mode is for reading specs from existing Figma designs. html2design is for creating Figma designs from existing HTML/CSS. You might use both, but for different problems.

Can html2design replace Figma Dev Mode for handoff?

Not fully. html2design doesn't produce annotation specs or CSS snippet export from Figma. For handoff from Figma to code, Dev Mode (or a similar spec tool) remains the right choice.

Does html2design work if I don't have a Figma Dev Mode subscription?

Yes. html2design is a standalone Figma plugin with its own subscription ($12/mo or $96/yr). It does not require Figma Dev Mode or a paid Figma plan — it works in any Figma file including those on free plans.
