01Introducing KMP Web Emulator — Live Preview Across All Platforms
Figma Forge now includes a KMP Web Emulator built directly into the design-to-code pipeline. Take your Figma design, generate idiomatic Kotlin Multiplatform Compose code, and immediately see it rendered live in the browser — showing you exactly how your app looks on Android, iPhone, and Desktop, without leaving your browser tab.
From Figma URL to Live KMP Preview in Under 60 Seconds
Paste your Figma URL → AI generates Compose Multiplatform code → Web Emulator renders it live across all your target platforms. Ship with visual confidence — every time.
02What Is the KMP Web Emulator?
The KMP Web Emulator is a browser-based rendering engine built into Figma Forge that executes your generated Kotlin Multiplatform Compose UI code visually — in real time — without requiring any native tooling installed on your machine.
Under the hood, it uses WebAssembly to compile and render Compose Multiplatform components directly in the browser. This means the UI you see is not a screenshot, not a static mockup, and not an approximation — it is your actual generated KMP code running in a virtual environment that faithfully replicates the target platform's layout and rendering characteristics.
How it fits into the Figma Forge pipeline:
📱 Android Preview
Material 3 design system, proper status bar, Android navigation gestures — exactly what your users will see.
⚡ Instant Render
No Gradle build, no emulator boot. Your Compose UI appears in seconds directly in the browser.
✓ Quality Checked
Pixel accuracy validated against your Figma design before this preview was generated.
03The Problem KMP Developers Have Been Living With
If you build with Kotlin Multiplatform today, you know the pain. You write your Compose Multiplatform UI, and you have essentially no good way to quickly see what it looks like across platforms without spinning up a full development environment.

04How the KMP Web Emulator Actually Works
The technical implementation is what makes this genuinely new. Here is what happens from the moment you click "Start Forge" to the moment you see your UI running live.
Step 1 — Figma Design Analysis
Figma Forge pulls your complete design tree from the Figma API — components, auto-layout frames, design tokens, variants, and typography. The AI pipeline analyzes structural intent, not just pixel values. It identifies component boundaries, layout patterns (flex, grid, stacking), color tokens, and spacing scales.
Step 2 — KMP Code Generation
The pipeline generates idiomatic Kotlin Multiplatform Compose Multiplatform code — not HTML approximations, not static exports. The output uses proper @Composable functions, Modifier chains, Material 3 design tokens, and platform-specific adaptations (Android vs iOS vs Desktop).
Step 3 — WebAssembly Compilation and Rendering
The generated Compose Multiplatform code is compiled to WebAssembly using the Compose Multiplatform for Web (Compose WASM) runtime. This is the same runtime JetBrains uses for their Compose Web target — meaning what you see in the emulator is faithful to what runs natively on Android, iOS, and Desktop.
Step 4 — Platform Switching
Switch between Android, iPhone, and Desktop modes in one click. Each mode applies the correct viewport dimensions, platform-specific UI conventions (Material 3 for Android, Cupertino-style for iOS, desktop window chrome), and platform-appropriate navigation patterns. What you see is what your users will see.
05Figma to Code in 2026 — The Full Picture
The KMP Web Emulator is the newest feature in Figma Forge's complete design-to-code pipeline. To understand why it matters so much, it helps to understand the full problem it solves.
"Figma to code" means automatically converting Figma designs into front-end code usable directly in production. The idea has existed for years — but until now, every tool either produced unusable output, didn't support KMP at all, or gave you no way to verify what was generated before you committed it to your codebase.
What Figma Forge Does Differently
KMP-First Architecture
Built from day one for Kotlin Multiplatform — not bolted on later. The only tool in the market with this focus.
Live Preview Before Export
The web emulator means you see the result before you commit it. No blind trust in AI-generated code.
Clean Semantic Output
No absolute positioning, no div soup. Proper Compose Multiplatform idioms, Tailwind for React, semantic HTML5.
Quality Validation
Set a pixel accuracy threshold. The pipeline validates before export. Failed jobs show exactly why.
Multi-Framework Simultaneously
React + Next.js + KMP in one forge job. One Figma design produces three production codebases.
Full Transparency
Diff viewer and live logs show every AI decision. No black boxes — full pipeline visibility.

07Who Benefits Most from KMP Web Emulator
Cross-Platform Mobile Teams
If your team builds with KMP, this is the feature you have been waiting for. Stop maintaining separate Android and iOS UI codebases. With Figma Forge, one Figma design generates both your React web component and your Compose Multiplatform mobile screens — and you see them rendered live before a single line ships.
"KMP support plus live preview changed everything. We see Android, iOS, and Desktop in one browser tab. This is the tool our team needed 2 years ago."
— Sofia M., Mobile Lead, Fintech startup using KMPSaaS Startups Building MVPs
Founder teams with no dedicated frontend engineer use Figma Forge to ship their first product faster. The web emulator means even non-technical founders can review the mobile UI and approve it before engineering time is spent. What used to be a week of back-and-forth is now a 30-minute forge job.
Design System Teams
Enterprise design teams keep their component libraries in sync across web and mobile. Design token changes in Figma propagate automatically to both React and KMP outputs, and the emulator confirms the change looks correct on all platforms before the PR is merged.

09What's Next for Figma Forge in 2026
The KMP Web Emulator is the foundation for a series of capabilities we are building throughout 2026. The roadmap includes full application generation (not just components — complete routed apps), bidirectional sync (code changes flowing back to Figma), and automated CI/CD triggers that run forge jobs when your Figma file is updated.
The underlying principle stays the same: eliminate every manual step between your designer's Figma file and your engineer's production commit. The KMP Web Emulator eliminates the most painful step — verifying that the generated code actually looks right across platforms.

FAQFrequently Asked Questions
Does Figma Forge really generate KMP code from Figma?
Yes — and it's the only tool in the world that does. Figma Forge generates idiomatic Kotlin Multiplatform Compose Multiplatform components from any Figma design, targeting Android, iOS, and Desktop. The KMP Web Emulator then renders them live in your browser before export.
Do I need Android Studio or Xcode to use the KMP emulator?
No — that is the entire point. The web emulator runs entirely in your browser using WebAssembly. No IDE, no simulator, no SDK, no native tooling of any kind. Works on Windows, Mac, and Linux.
What does the 200 free points cover?
200 points per month cover approximately 5 to 10 complete component screens with KMP + React output and live preview. All features included — no credit card required. See full pricing.
Is the generated KMP code production-ready?
For most components — yes. The quality validation threshold ensures output meets your accuracy standard before export. The KMP web emulator gives you visual confirmation before you commit a single line. Simple UI (cards, navbars, forms, hero sections) requires zero editing.
