Is there an alternative to Google Forms?

Question

Web development

Is there a form where you can create a questionnaire and information from which will be aggregated in a spreadsheet editor? The same Google spreadsheets.
I will describe the example that I need.
Registration of participants for competitions. The leader registers in the system and then registers commands for himself. That is, the manager does not need to write his data a hundred times. Enter once and that's it.
