The main difference is probably that autotab outputs a Python script, which is easier to integrate with existing Python codebases.

Going forward I think the flexibility of Python code & the Python ecosystem will make it easier to build a bunch more things we want to do. For example, a lot of browser-based work is not totally deterministic but rather requires more intelligence during the automation, e.g. summarizing information on a web page or dynamically filling in a text box with the right answer.
