 In the `docs/src/app/` MDX files, always use HTML `<table>` syntax for tables (not markdown pipe tables). This matches the existing convention across the docs site.
 
+## Dual Architecture (Node.js + Native)
+
+The codebase has two daemon implementations:
+
+- **Node.js/Playwright** (default) -- `src/daemon.ts`, `src/actions.ts`, `src/browser.ts`, and the rest of `src/`
+- **Rust/Native** (experimental, `--native` or `AGENT_BROWSER_NATIVE=1`) -- `cli/src/native/daemon.rs`, `cli/src/native/actions.rs`, `cli/src/native/browser.rs`, and the rest of `cli/src/native/`
+
+When modifying browser automation logic (commands, actions, protocol handling), changes **must** be made in **both** paths:
+
+| Node.js Path | Native Path |
+|---|---|
+| `src/actions.ts` | `cli/src/native/actions.rs` |
+| `src/browser.ts` | `cli/src/native/browser.rs` |
+| `src/daemon.ts` | `cli/src/native/daemon.rs` |
+| `src/protocol.ts` | `cli/src/native/cdp/client.rs` |
+| `src/snapshot.ts` | `cli/src/native/snapshot.rs` |
+| `src/state-utils.ts` | `cli/src/native/state.rs` |
+
+New commands must be implemented in both paths, or explicitly stubbed in the native path with a clear `"Not yet implemented: {action}"` error. The goal is eventual full migration to native, but until then both paths must stay in sync.
+
+## Testing
+
+### Unit Tests
+
+```bash
+cd cli && cargo test
+```
+
+Runs all unit tests (~320 tests). These are fast and don't require Chrome.
+
+### End-to-End Tests
+
+```bash
+cd cli && cargo test e2e -- --ignored --test-threads=1
+```
+
+Runs 18 e2e tests that launch real headless Chrome instances and exercise the full native daemon command pipeline. Requirements:
+
+- Chrome must be installed
+- Must run serially (`--test-threads=1`) to avoid Chrome instance contention
+- Tests are `#[ignore]`'d so they don't run during normal `cargo test`
+
+The e2e tests live in `cli/src/native/e2e_tests.rs` and cover: launch/close, navigation, snapshots, screenshots, form interaction, cookies, storage, tabs, element queries, viewport/emulation, domain filtering, diff, state management, error handling, and Phase 8 commands.
+
+### Linting and Formatting
+
+```bash
+cd cli && cargo fmt -- --check   # Check formatting
+cd cli && cargo clippy            # Lint
+```
+

 # Changelog
 
+## v0.16.0
+
+<p className="text-[#888] text-sm">March 2026</p>
+
+### New Features
+
+- **Native Rust daemon (experimental).** A pure Rust daemon that communicates with Chrome directly via the Chrome DevTools Protocol (CDP), eliminating Node.js and Playwright dependencies entirely. Enable with `--native`, `AGENT_BROWSER_NATIVE=1`, or `"native": true` in your config file. Supports 150+ commands with full parity to the default Node.js daemon.
+
+```bash
+# Via flag
+agent-browser --native open example.com
+
+# Via environment variable
+export AGENT_BROWSER_NATIVE=1
+agent-browser open example.com
+```
+
+Or add to `agent-browser.json`:
+
+```json
+{"native": true}
+```
+
+### Architecture
+

+  <thead>
+    <tr><th></th><th>Default (Node.js)</th><th>Native (<code>--native</code>)</th></tr>

+    <tr><td><strong>Protocol</strong></td><td>Playwright protocol</td><td>Direct CDP / WebDriver</td></tr>
+    <tr><td><strong>Install size</strong></td><td>Larger (Node.js + npm deps)</td><td>Smaller (single binary)</td></tr>
+    <tr><td><strong>Browser support</strong></td><td>Chromium, Firefox, WebKit</td><td>Chromium, Safari (via WebDriver)</td></tr>
+    <tr><td><strong>Stability</strong></td><td>Stable</td><td>Experimental</td></tr>
+  </tbody>
+</table>
+
+### What's Supported
+
+All core commands work in native mode: navigation, interaction (click, fill, type, press, hover, scroll, drag), observation (snapshot, screenshot, eval), state management (cookies, storage, state save/load), tabs, emulation (viewport, device, timezone, locale, geolocation), streaming, diffing, recording, and profiling.
+
+The native daemon also includes a WebDriver backend for Safari and iOS support.
+
+### Known Limitations
+
+- Firefox and WebKit are not yet supported (Chromium and Safari only)
+- Playwright trace format is not available (uses Chrome's built-in tracing)
+- HAR export is not available
+- Network route interception uses CDP Fetch domain instead of Playwright's route API
+- The native and Node.js daemons share the same session socket. Use `agent-browser close` before switching between modes.
+
+See the [Native Mode](/native-mode) page for full details.

+agent-browser includes an experimental native Rust daemon that communicates with Chrome directly via the Chrome DevTools Protocol (CDP), eliminating the Node.js and Playwright dependencies entirely.
+
+## Enabling Native Mode
+
+Native mode is opt-in. Enable it with the `--native` flag or the `AGENT_BROWSER_NATIVE` environment variable.
+
+### CLI Flag
+
+```bash
+agent-browser --native open example.com
+agent-browser --native snapshot
+agent-browser --native close
+```
+
+### Environment Variable
+
+Set `AGENT_BROWSER_NATIVE=1` to avoid passing the flag on every command:
+
+```bash
+export AGENT_BROWSER_NATIVE=1
+agent-browser open example.com
+agent-browser snapshot
+agent-browser close
+```
+
+### Config File
+
+Add `"native": true` to your `agent-browser.json`:
+
+```json
+{"native": true}
+```
+

+    <tr><td><strong>Browser support</strong></td><td>Chromium, Firefox, WebKit</td><td>Chromium, Safari (via WebDriver)</td></tr>
+    <tr><td><strong>Stability</strong></td><td>Stable</td><td>Experimental</td></tr>
+  </tbody>
+</table>
+
+## What Works
+
+All core commands are supported in native mode:
+
+- Navigation: `open`, `back`, `forward`, `reload`
+- Interaction: `click`, `fill`, `type`, `press`, `hover`, `select`, `check`, `uncheck`, `scroll`, `focus`, `clear`, `upload`, `drag`
+- Observation: `snapshot`, `screenshot`, `eval`, `get text/html/value/attr/count/box/styles`, `is visible/enabled/checked`
+- State: `cookies get/set/clear`, `storage local/session`, `state save/load/list`
+- Tabs: `tab new/list/close`, tab switching
+- Emulation: `set viewport`, `set device`, `set geo`, user agent, timezone, locale
+- Streaming: WebSocket screencast and remote input
+- Diffing: `diff snapshot`, `diff url`
+- Recording: `record start/stop`
+- Profiling: `profiler start/stop`, `trace start/stop`
+
+## Known Limitations
+
+- **Firefox and WebKit** are not yet supported (Chromium and Safari only)
+- **Playwright trace format** is not available (native tracing uses Chrome's built-in tracing)
+- **HAR export** is not available
+- **Network route interception** uses CDP Fetch domain instead of Playwright's route API
+
+## Switching Between Modes
+
+The native daemon and Node.js daemon share the same session socket. You cannot run both simultaneously for the same session. Close the current daemon before switching:
+
+```bash
+agent-browser close
+export AGENT_BROWSER_NATIVE=1
+agent-browser open example.com
+```

+## Experimental: Native Mode
+
+agent-browser has an experimental native Rust daemon that communicates with Chrome directly via CDP, bypassing Node.js and Playwright entirely. It is opt-in and not recommended for production use yet.
+
+```bash
+# Enable via flag
+agent-browser --native open example.com
+
+# Enable via environment variable (avoids passing --native every time)
+export AGENT_BROWSER_NATIVE=1
+agent-browser open example.com
+```
+
+The native daemon supports Chromium and Safari (via WebDriver). Firefox and WebKit are not yet supported. All core commands (navigate, snapshot, click, fill, screenshot, cookies, storage, tabs, eval, etc.) work identically in native mode. Use `agent-browser close` before switching between native and default mode within the same session.
