A Chrome extension that spots the login portal on campus, hotel and airport Wi-Fi, fills in your details, and gets you online before you’ve opened a tab.

See how it worksSet it up

From joining Wi-Fi to online, with no clicks.

It asks one question

You join the network. The extension checks a tiny Google address that should answer “204”, which means you’re really online.

The portal answers instead

Instead of 204, the network sends a redirect to its login page. That’s how a portal gives itself away.

It logs in, out of sight

In a background tab, your saved details fill the form, the terms box gets ticked, and Connect gets pressed.

It checks again, then closes up

When the answer is 204, the tab closes and a quiet notification tells you you’re connected.

Join a pretend network with auto-login on, then off, and compare how long it takes to get online.
