Focuses solely on basic command execution without built-in features like file management, database access, or error handling, which are common in more comprehensive webshells.

The Ninja variant requires base64 encoding and header manipulation, which can be error-prone without the provided handler script, as admitted in the README's 'a bit complex' note.

README is brief and lacks detailed setup instructions, troubleshooting guides, or security best practices, relying on users to figure out nuances like command encoding.

Code snippets show no error handling mechanisms, which could lead to silent failures or exposure if parameters are malformed or execution fails.
