WiFiDog review
An open-source Linux gateway daemon for teams building a self-hosted hotspot.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WiFiDog is an open-source captive-portal gateway project for wireless community groups and individuals operating public hotspots. The gateway component is a client daemon designed to run on embedded hotspot hardware, including Linux-based self-hosted deployments. It redirects users to an authentication server and lifts access restrictions according to the server’s response. That makes it relevant to technical teams assembling their own hotspot system, rather than operators seeking a turnkey hosted guest Wi-Fi service.
The gateway communicates with the authentication server using WiFiDog Protocol Version 1. A configurable gateway ID identifies the gateway to the server and can be used for monitoring and statistics purposes. This keeps the described feature set focused on the gateway-server exchange: WiFiDog’s gateway handles redirection and applies an authentication decision, while the project describes the authentication server as a separate component. Teams should account for both pieces when planning a deployment.
WiFiDog is a fit for technical teams that want an open-source, self-hosted gateway daemon and can work with a separate authentication server. Its stated role is narrow: the repository is the gateway component, not a hosted management service. Organizations looking for a managed guest Wi-Fi offering should consider a different kind of product; WiFiDog suits builders who want to operate the hotspot infrastructure themselves.
WiFiDog pros and cons
- Where it wins
- Runs as a client daemon on embedded hotspot hardware
- Redirects users to an authentication server and applies its response
- Configurable gateway ID can support server identification and monitoring
- Where it doesn't
- This repository contains the gateway component, not the authentication server
- Requires a separate authentication server component
- Its described role is gateway access handling, not hosted guest Wi-Fi management
