SparkLabs
Explosively Great Apps
SparkLabs is an independent software company founded in 2008 that develops commercial desktop and mobile applications focused on network security and user privacy. Its main product is Viscosity, an OpenVPN client for macOS and Windows that helps users connect to VPNs, with support for both new VPN users and more advanced network and IT use cases. The company also offers Ovpngen, a free OpenVPN configuration generator.
Viscosity is available for macOS and Windows, with regular maintenance releases that update OpenVPN and OpenSSL and address platform-specific issues. Ovpngen supports ARM64 architectures and Linux distributions, and includes SAN generation and other configuration features. SparkLabs is funded through software sales rather than outside investment or advertising, and its apps are sold as commercial products; the pages do not specify a free plan, trial, or seat-based or usage-based packaging.
