We all know that the Forms widget is not available in Elementor Free version. As such, the question becomes valid whether Metform needs Elementor Pro to be installed.
So, the answer to this is, No.
Yes, you don't need to have the Elementor Pro version for Metform to work on your WordPress site. Because Metform is not an extension but a separate widget for Elementor and can be used with Elementor Free version without an issue and with all its features.
