t-io is a Java network programming framework built on Java AIO that simplifies building high-performance TCP/UDP and WebSocket servers. It provides built-in heartbeat handling, user/token/group binding, and per-channel traffic monitoring, and is widely used for IoT, IM, and customer service applications.

Use cases

• build an instant messaging server in Java
• implement custom TCP protocols for IoT devices
• create a WebSocket server for real-time chat
• manage long-lived connections with heartbeat detection
• build a customer service messaging backend
• unify TCP and UDP business logic behind one API

When to choose

• you need high-performance long-connection networking on the JVM
• you want built-in user, token, and group binding for IM-style apps
• you need both TCP and UDP support with a unified API
• you want per-connection traffic and heartbeat monitoring out of the box

When to avoid

• you need a general-purpose HTTP/REST web framework
• you prefer Netty's larger ecosystem and community
• your project is not on the JVM
• you need non-blocking I/O on platforms without Java AIO support
