+# Unbundle Mode
+
+Preserve source directory structure in output.
+
+## Overview
+
+Unbundle mode (also called "bundleless" or "transpile-only") outputs files that mirror your source structure, rather than bundling everything into single files. Each source file is compiled individually with a one-to-one mapping.
+
+## Basic Usage
+
+### CLI
+
+```bash
+tsdown --unbundle
+```
+
+### Config File
+
+```ts
+export default defineConfig({
+  entry: ['src/**/*.ts', '!**/*.test.ts'],
+  unbundle: true,
+})
+```
+
+## How It Works
+
+### Source Structure
+
+```
+src/
+├── index.ts
+├── utils/
+│   ├── helper.ts
+│   └── format.ts
+└── components/
+    └── button.ts
+```
+
+### With Unbundle
+
+**Config:**
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  unbundle: true,
+})
+```
+
+**Output:**
+```
+dist/
+├── index.mjs
+├── utils/
+│   ├── helper.mjs
+│   └── format.mjs
+└── components/
+    └── button.mjs
+```
+
+All imported files are output individually, preserving structure.
+
+### Without Unbundle (Default)
+
+**Output:**
+```
+dist/
+└── index.mjs  (all code bundled together)
+```
+
+## When to Use
+
+### Use Unbundle When:
+
+✅ Building monorepo packages with shared utilities
+✅ Users need to import individual modules
+✅ Want clear source-to-output mapping
+✅ Library with many independent utilities
+✅ Debugging requires tracing specific files
+✅ Incremental builds for faster development
+
+### Use Standard Bundling When:
+
+❌ Single entry point application
+❌ Want to optimize bundle size
+❌ Need aggressive tree shaking
+❌ Creating IIFE/UMD bundles
+❌ Deploying to browsers directly
+
+## Common Patterns
+
+### Utility Library
+
+```ts
+export default defineConfig({
+  entry: ['src/**/*.ts', '!**/*.test.ts'],
+  format: ['esm', 'cjs'],
+  unbundle: true,
+  dts: true,
+})
+```
+
+**Benefits:**
+- Users import only what they need
+- Tree shaking still works at user's build
+- Clear module boundaries
+
+**Usage:**
+```ts
+// Users can import specific utilities
+import { helper } from 'my-lib/utils/helper'
+import { Button } from 'my-lib/components/button'
+```
+
+### Monorepo Shared Package
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm'],
+  unbundle: true,
+  outDir: 'dist',
+})
+```
+
+### TypeScript Compilation Only
+
+```ts
+export default defineConfig({
+  entry: ['src/**/*.ts'],
+  format: ['esm'],
+  unbundle: true,
+  minify: false,
+  treeshake: false,
+  dts: true,
+})
+```
+
+Pure TypeScript to JavaScript transformation.
+
+### Development Mode
+
+```ts
+export default defineConfig((options) => ({
+  entry: ['src/**/*.ts'],
+  unbundle: options.watch,  // Unbundle in dev only
+  minify: !options.watch,
+}))
+```
+
+Fast rebuilds during development, optimized for production.
+
+## With Entry Patterns
+
+### Include/Exclude
+
+```ts
+export default defineConfig({
+  entry: [
+    'src/**/*.ts',
+    '!**/*.test.ts',
+    '!**/*.spec.ts',
+    '!**/fixtures/**',
+  ],
+  unbundle: true,
+})
+```
+
+### Multiple Entry Points
+
+```ts
+export default defineConfig({
+  entry: {
+    index: 'src/index.ts',
+    cli: 'src/cli.ts',
+  },
+  unbundle: true,
+})
+```
+
+Both entry files and all imports preserved.
+
+## Output Control
+
+### Custom Extension
+
+```ts
+export default defineConfig({
+  entry: ['src/**/*.ts'],
+  unbundle: true,
+  outExtensions: () => ({ js: '.js' }),
+})
+```
+
+### Preserve Directory
+
+```ts
+export default defineConfig({
+  entry: ['src/**/*.ts'],
+  unbundle: true,
+  outDir: 'lib',
+})
+```
+
+**Output:**
+```
+lib/
+├── index.js
+├── utils/
+│   └── helper.js
+└── components/
+    └── button.js
+```
+
+## Package.json Setup
+
+```json
+{
+  "name": "my-library",
+  "type": "module",
+  "main": "./dist/index.js",
+  "types": "./dist/index.d.ts",
+  "exports": {
+    ".": "./dist/index.js",
+    "./utils/*": "./dist/utils/*.js",
+    "./components/*": "./dist/components/*.js"
+  },
+  "files": ["dist"]
+}
+```
+
+Or use `exports: true` to auto-generate.
+
+## Comparison
+
+| Feature | Bundled | Unbundled |
+|---------|---------|-----------|
+| Output files | Few | Many |
+| File size | Smaller | Larger |
+| Build speed | Slower | Faster |
+| Tree shaking | Build time | User's build |
+| Source mapping | Complex | Simple |
+| Module imports | Entry only | Any module |
+| Dev rebuilds | Slower | Faster |
+
+## Performance
+
+### Build Speed
+
+Unbundle is typically faster:
+- No bundling overhead
+- Parallel file processing
+- Incremental builds possible
+
+### Bundle Size
+
+Unbundle produces larger output:
+- Each file has its own overhead
+- No cross-module optimizations
+- User's bundler handles final optimization
+
+## Tips
+
+1. **Use with glob patterns** for multiple files
+2. **Enable in development** for faster rebuilds
+3. **Let users bundle** for production optimization
+4. **Preserve structure** for utilities/components
+5. **Combine with DTS** for type definitions
+6. **Use with monorepos** for shared code
+
+## Troubleshooting
+
+### Too Many Files
+
+- Adjust entry patterns
+- Exclude unnecessary files
+- Use specific entry points
+
+### Missing Files
+
+- Check entry patterns
+- Verify files are imported
+- Look for excluded patterns
+
+### Import Paths Wrong
+
+- Check relative paths
+- Verify output structure
+- Update package.json exports
+
+## CLI Examples
+
+```bash
+# Enable unbundle
+tsdown --unbundle
+
+# With specific entry
+tsdown src/**/*.ts --unbundle
+
+# With other options
+tsdown --unbundle --format esm --dts
+```
