This is a TCP/UDP network protocol debugging tool that makes network debugging as easy as chatting with friends, turning tedious network debugging into something fun.

【Core Features】

• TCP/UDP Server
Create local servers that listen on specified ports and accept client connections. Configure auto-reply (reply to any message or pattern-matched messages).

• TCP/UDP Client
Connect to local or remote servers for real-time message sending and receiving. Supports connection status monitoring and automatic reconnection.

• Message Formats
Supports three formats: plain text, hexadecimal, and Base64. Configurable text encoding (UTF-8, etc.).

• DNS Query
Query common DNS servers like Google DNS, Cloudflare DNS, and 114 DNS to resolve domain records.

• Replay Testing
Supports message replay: save your sent messages and automatically resend them every second.
