WebSocket Terminal

The WebSocket Client plugin turns IO Ninja into a highly configurable raw WebSocket client-side terminal.

WebSockets are widely used in modern web programming. They allow two-way communication between a browser and a server as opposed to the traditional HTTP request-response pattern. This helps build modern web apps in a much more natural, flexible, and efficient way.

Unfortunately, there are not many tools available for debugging raw WebSocket connections. What if you want to see how your server responds to a malformed WebSocket command? Or stress-test it by sending a barrage of requests over a WebSocket connection?

The WebSocket Client plugin fills the existing gap. With it, IO Ninja can be used for convenient GUI-based debugging of raw client-side WebSocket connections.

What Makes WebSocket Client Special?

Both secure and insecure WebSockets are supported
The whole range of configurable client-side SSL options is available for secure WebSockets
Select between WebSocket text or binary frames — automatically or manually
Send WebSocket pings manually
Re-connect if connection is lost
Specify local address to connect from
Control low-level TCP options (Nagle, TCP RST, keep-alives)

And of course, all the platform features that makes IO Ninja stand out:

Powerful & Beautiful Logging Engine

The Ninja Scroll logging engine is the heart of IO Ninja! It offers many unique and useful features you won't find in other WebSocket clients, such as interleaving binary data with informational messages for a clear timeline of events, switching between hex-view and plain-text view of binary data, a regex markup engine for highlighting data based on regular expressions, and many others!

Versatile Transmission Facilities

IO Ninja features convenient and powerful tools for preparing WebSocket packets before transmission. We offer a plain text editor with support for C ESC-sequences to encode special characters, a modern Unicode-enabled hex editor, and a file transmit feature.

A history of recently transmitted WebSocket packets is maintained, and you can also build your own libraries of commonly used packets — then send those packets with a mouse click!

Scriptability

With the Script Pane, you can generate WebSocket packets programmatically, wait for and react to WebSocket events, and automatically reply to incoming data, etc.

For more complex binary packets, you can describe the structure and methods for updating checksums or other auto-calculated fields as a Packet Template, then conveniently fill in the fields in a property grid.
