When NOT to use openbrowser

  • - When you require a highly customized or specialized automation process that goes beyond typical web interactions (e.g., complex enterprise software automation).
  • - If your application does not benefit from real-time, autonomous task completion through natural language commands.
  • - For scenarios where JavaScript/TypeScript proficiency is lacking, as the framework might be more challenging to adapt or require a steeper learning curve for non-TypeScript developers.
