  • Limited to Shell Commands
    Focused solely on shell commands, it doesn't cover other scripting languages or programming environments.

  • Performance Issues
    For extremely large inputs or very complex regular expressions, the tool may experience performance lags or slowdowns.
  • Limited Advanced Features
    RegExr may lack some advanced features found in more specialized or professional regex tools, such as integration with development environments or extensive scripting capabilities.
