What is Application Server Software for Windows?

Application server software provides a platform for deploying, managing, and running applications, typically for web or enterprise environments. These servers handle the backend logic of applications, facilitating the connection between client devices and databases or other services. Application servers often provide middleware services such as security, transaction management, and messaging, enabling the smooth execution of applications. They are designed to support multiple users simultaneously and ensure high availability, scalability, and performance of applications. This software is commonly used in environments where complex, data-intensive applications are developed, such as in e-commerce platforms, enterprise resource planning (ERP), and customer relationship management (CRM) systems.

horizOn

ProjectMakers

horizOn takes the backend work off the hands of indie developers, small and mid range studios. Instead of dealing with servers, databases, and API endpoints, you drop an SDK into your game engine and get instant access to 9 ready-made features: user management, leaderboards, cloud saves, remote config, in-game news, gift codes, user feedback, crash reporting, and server logging. The backend runs on dedicated infrastructure across three regions (EU, US, Asia) with 99.98% uptime. The biggest difference compared to Firebase, Supabase, or PlayFab: pricing is fixed. You pay a flat monthly rate regardless of how many requests your game makes. There is a free starter tier, and if you prefer, you can self-host horizOn (simple version of our cloud solution) on your own server.
