Tunnelblick review
A capable OpenVPN client for Mac users who already have VPN server access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Tunnelblick is a free, open-source macOS application for managing OpenVPN connections. It gives Mac users graphical control over OpenVPN client and server connections, supports multiple VPN configurations, and can connect to company, personal, or third-party VPN servers. It is aimed at people who already have access to a compatible VPN server and the required configuration and encryption files, rather than customers looking for a complete VPN subscription.
Its strongest area is configuration management. Tunnelblick imports .conf, .ovpn, and .tblk files, lets users maintain multiple VPN profiles, and provides DNS and WINS controls through connection settings. Users can select OpenVPN and OpenSSL or LibreSSL versions, while automatic connection on launch or computer startup supports recurring connection workflows. The kill switch can disable network access after a disconnection, adding a practical control for users who want to avoid unprotected traffic.
Tunnelblick also includes built-in update checking and signed downloads, and its open-source model keeps the application free. The trade-off is scope: it supplies the macOS client and related drivers, but not VPN server infrastructure, subscriptions, provider networks, streaming access, or torrenting features. Choose Tunnelblick if you manage your own OpenVPN access or need a configurable Mac client. Choose a complete VPN service instead if you want a supplied network, account-based access, or provider-managed servers.
