Matoi is a lightweight tool that lets you talk to websocket servers directly from your command line. Think of it as a chat interface for testing, you type messages into your terminal, they get sent to a websocket server, and any responses come back and print to your screen. It's designed specifically for developers who are building or debugging websocket servers and need a quick way to send test messages without writing code. The way it works is straightforward. You run the tool with a server address (a websocket URL), and it opens a connection to that server. Then you can type messages directly into your terminal, each line you enter gets sent to the server as plain text. Any messages the server sends back appear immediately in your terminal. It's essentially a two-way text exchange, making it easy to see exactly what your server is responding with. Developers building real-time applications, chat systems, live notifications, collaborative tools, or any service that uses websockets, would use this during development and testing. Instead of spinning up a full client application or writing test code, you can just run matoi, connect to your development server, and manually test if messages are being sent and received correctly. It's a fast, no-fuss way to verify your websocket logic is working as expected. The tool is written in Go, a systems programming language known for being lightweight and fast. To get started, you download the source code and compile it yourself using Go version 1.17 or newer, then you're ready to use it. Because it's so minimal and focused on one job, it starts instantly and requires almost no setup, making it handy to have in your toolkit when you're actively developing websocket features.
