Wavvy GitHub v2.0

Join the Wi-Fi.The login pageis handled.

Wavvy is an intelligent Chrome extension that spots captive portals on campus, hotel, and airport Wi-Fi, auto-fills your credentials, and gets you online before you’ve opened a tab.

Pauses after three failed logins
Details stay in your browser

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

It asks one question

You join the network. Wavvy checks a tiny probe 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.

Wavvy monitors connectivity quietly and checks again when you wake your laptop. It never guesses: after three failed logins it pauses for five minutes, so a wrong password can’t lock you out. Your credentials stay 100% in your local browser sandbox.

Try it yourself.

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