Advice for side project idea

Hey everyone! Happy to be first time posting :)

I'm a third year CS student and so I am looking to build a project to build my experience/portfolio. I thought of building a cloud-based IDE, somewhat similar to Coderpad but for personal practice instead of interviewing, and i have some vague thoughts of features surrounding that. I'm a little worried that it maybe overdone though. Anyone know if this is overdone or not? If it is I guess I can still put it as a project where I learnt skills, I just wouldn't get real users I guess. Thank you for any advice!
