Portal ready when you need it.

Works in the background, so you can stay in the moment.

Purpose-built for public spaces, CafeSignal focuses on open Wi-Fi, portal handling, and quiet status you can trust.

Auto-connect

Looks for suitable open public networks when your Mac is offline, then tries the best candidate without repeated clicks.

Portal detection

Checks whether normal internet works and opens the captive portal when the network still needs your action.

Private by design

Skips password, enterprise, paid, and account-only networks. CafeSignal does not collect personal browsing data.

Smart, simple, silent.

CafeSignal avoids aggressive reconnect loops. It checks your current connection first, scans at a low frequency, and only acts when there is a clear public-network opportunity.

It connects, checks the internet, and opens a portal only when needed.

Built with clear boundaries.

No password cracking, account bypassing, payment bypassing, or hidden portal submissions.
Password, enterprise, paid, voucher, and account-only networks are skipped or left for the user.
The app only needs enough local network state to decide whether public Wi-Fi help is useful.
