 ## [Unreleased]
 
+### Added - Web Backend Browser Auto-Launch
+
+**`--open` Flag for typedialog-web**
+- Added `--open` flag to auto-launch form in default web browser
+- Supported in both `typedialog-web` command and `nickel-roundtrip` subcommand
+- Graceful error handling: warnings if browser open fails, execution continues
+- Cross-platform support: macOS (`open`), Linux (`xdg-open`), Windows (`start`)
+
+**Usage Examples**
+```bash
+typedialog-web form.toml --open
+typedialog-web form.toml --port 8080 --open
+typedialog-web nickel-roundtrip input.ncl form.toml --output output.ncl --open
+```text
+
+**Benefits**
+- Improves UX: eliminates manual URL copy/paste steps
+- Aligns with industry standards (mdbook serve --open, http-server, etc.)
+- Faster development workflow: edit → view changes without manual browser navigation
+- Perfect for demos and user onboarding workflows
+
+**Documentation**
+- Updated `docs/web/README.md` with `--open` examples in "Basic Usage" section
+- Added "Browser Auto-Launch" subsection explaining use cases and behavior
+
 ### Added - Unified Command Interface (Dispatcher)
 
 **Dispatcher for Backend Access**

+### Browser Auto-Launch
+
+Use `--open` to automatically open the form in your default web browser:
+
+```bash
+# Opens http://localhost:8080 automatically
+typedialog-web --config form.toml --port 8080 --open
+```text
+
+This is particularly useful for:
+
+- **Development**: Edit form and see changes instantly without manual URL entry
+- **Demonstrations**: Show forms to stakeholders without extra steps
+- **Scripting**: Automated workflows that need visual interaction
+- **User Experience**: Users don't need to copy/paste URLs
+
+If browser opening fails (e.g., in headless environments), a warning is shown but the form continues to serve normally.
