Cross-Platform VPN Client

Context

The client set out to launch their own VPN product. NekaSoft joined at the start and took on the technical delivery of the client applications for Windows, macOS, Linux, Android, and iOS.

The client brought well-defined business requirements and finished design mockups. The choice of technical approach, architecture, and implementation tools was left to NekaSoft.

What we owned

We translated the business requirements into a technical solution and were responsible for delivery and release on all five platforms.

Solution

The applications were built with cross-platform technologies, with the main development in JavaScript and TypeScript.

• Electron apps for Windows, macOS, and Linux
• Cordova apps for iOS and Android
• Targeted native code, including Swift on Apple platforms
• Xray integration and custom routing
• Complex network logic
• Full release cycle: builds, signing, certificates, store submission

The apps were built on a shared cross-platform core: Electron for desktop and Cordova for mobile, with native code added where platform-specific integration required it. The hardest part was the Apple ecosystem, where the network implementation, platform restrictions, and app store review requirements had to be handled at once.

Result

The client got a production-ready VPN product with applications for Windows, macOS, Linux, Android, and iOS.

• The applications were published and reached real users
• They became the client side of a commercial VPN service
• The client was able to launch, develop, and sell their own VPN product on the major desktop and mobile platforms

Delivery

The main development ran for about two years.

After the main development cycle, the product continued to evolve with the growing involvement of the client's in-house technical team. The applications remain in production and in commercial use to this day.

Technology

Swift was used for native integrations where the cross-platform layer was not enough on Apple platforms.
