Developing nocode functions represents a significant amount of work, which I accomplish in my free time. I don't charge for it, so that it finds a wider audience (including students, journalists, hobbyists...). In return, I hope to use it to deploy the new functions I will create in the course of my academic research, and I hope it will benefit my studies: the user feedback on the functions will help me refine them and make them more robust. Hopefully, a community of users will grow and will generate interesting ideas for new developments as well!
Second, depending on the interest of the users, I consider developing API versions for high volume, high availability versions of the functions, typically for professional use by enterprises, not individuals. These APIs would not be free as significant server costs would be involved.
