Wink is a native Mac browser (AppKit and SwiftUI) on the Chromium engine. Agents are first-class: a built-in MCP server lets Claude Code, or any MCP client, browse with Wink, in fewer steps than Playwright. You see every step, and Wink asks before anything consequential.
Why Wink
Quick start
1. Install. Download Wink (signed and notarized), drag it to Applications and open it once. If Claude Code is on your Mac, Wink adds itself to Claude Code's MCP servers. Nothing opens until an agent uses a tool; then Wink opens by itself.
2. Ask. In any Claude Code session:
Open localhost:3000 in Wink, sign up with a test account, and tell me what errors show up in the console.
The first time, Wink asks whether to let Claude Code browse.
3. Go headless (optional). For parallel sessions or CI, give each agent a private, invisible, throwaway Wink:
claude mcp add --scope user wink-headless -- /Applications/Wink.app/Contents/MacOS/wink-mcp --headless
claude mcp add --scope user wink -- /Applications/Wink.app/Contents/MacOS/wink-mcp
Any client that speaks MCP over stdio works the same way:
{ "mcpServers": { "wink": { "command": "/Applications/Wink.app/Contents/MacOS/wink-mcp" } } }
To stop Wink adding itself, turn it off in Settings › Agents or run claude mcp remove wink; it won't add itself again.
Wink vs Playwright
Same agent, same prompts, both browsers headless and private. Claude Sonnet 5.5 ran eleven browser tasks three times in each. Wink 0.8.1 was against Playwright MCP 0.0.85, with Playwright's network, storage, PDF and DevTools options turned on.
| Tool calls | Time | Input tokens | Tasks done |
|---|
| Wink | 21% fewer | 28% less | 46% fewer | 33 / 33 |
| Playwright MCP | | | | 33 / 33 |
Wink was faster on each of the eleven tasks and never needed more steps. Two more comparisons:
- Real websites: on six public sites (Sauce Demo, The Internet, TodoMVC, Hacker News, GitHub, MDN), Wink needed 16% fewer steps and 30% fewer tokens with Sonnet, and 56% fewer steps and 53% fewer tokens with Haiku.
- Many at once: eight scripted sessions side by side finished about 3× faster, using 31% less memory.
When Playwright is still the tool: Wink runs on Macs, on Chromium. For test suites on Linux or Windows servers, in Firefox's and Safari's own engines, or headless by the hundred on a server farm, use Playwright. Wink's export_test writes the Playwright tests those servers run, so you can use both. Full method and every number: wink.minnebo.ai/vs-playwright.
What agents can do
Each of the 37 tools is built to save a model turn. find returns just the matching controls in milliseconds. Each action replies with what changed: dialogs that opened, controls that changed state, text that updated. batch runs up to 40 steps across page loads, by CSS selector, visible text or field label.
| Tools |
|---|
| Tabs | tabs_list get_active_tab tab_open tab_close tab_focus |
| Navigate | navigate go_back go_forward reload wait_for |
| Look | find snapshot read_page screenshot get_selection |
| Act | click type fill_form select_option press_key hover scroll drag upload_file handle_dialog batch |
| Develop | console_logs network_requests evaluate emulate mock_network storage |
| Keep | verify export_test trace record save_pdf |
Web developers get a workbench on localhost: requests in full with headers and bodies, mocks and offline mode, cookies and storage, phone sizes and dark mode, and JavaScript without prompts. export_test turns an agent's exploration into a Playwright test, and Wink's own CI runs those tests in Chromium, Firefox and WebKit. Details in docs/AGENTS.md.
You stay in charge
- You see it. A thin aurora rims the page an agent is using, Wink's eye moves to each target and winks on every click, and the activity pill lists every step.
- You can stop it. Pause or Stop in the pill, ⇧⌘. stops every agent, and clicking into an agent's page pauses it.
- It asks first. Before an agent sends, buys, deletes, uploads or connects, Wink asks you. After a burst of such actions on one site, it checks in.
- It sees only what you share. Agents use the tabs they open or the tabs you share with ⇧⌘E, and nothing else.
And it's a good browser
- Native and fast. No web-based browser chrome. Ready in about 265 ms, instant tab switching, and idle tabs sleep (five tabs: 858 MB → 421 MB).
- Winky, an assistant on the page. Press ⌘J and a prompt bar floats over the page, running on Claude or your local Claude Code. ⌥⌘J opens her sidebar for longer conversations.
- Easy to switch. File › Import from Another Browser… brings logins, history and bookmarks over from Chrome, Arc, Brave, Edge or Vivaldi, on your Mac only, leaving tracker cookies behind.
- Video that plays. H.264, AAC and HEVC are built in. DRM streaming (Netflix, Spotify) needs Widevine, which isn't in yet.
- Updates itself. Signed Sparkle updates. A daily update check carries anonymous usage counts you can switch off (details).
