Small add here, but if you do decide to recruit some help, I might consider starting with your users. By "developer tool", I presume you mean a tool for developers. That means that you have a talented user base. Might not be a bad idea to post a message to your forum, or post a notification to your app, or email your users. I wouldn't phrase it as "I'm overwhelmed", but saying something like "This is a powerful tool supported by a single CS student, and I'd love to bring in some help to advance development and/or respond to user needs. Does anyone want to contribute to the project?" Keep in mind that if this is your first time managing others, it will require some up-front investment of time. Managing people is difficult, but not impossible to become very good at. My advice for you at the outset is to be really clear and consistent about your goals, and to be open and honest with your community about the experiment you're undergoing. They'll give you a lot of credit for doing this as a student, and I think you'll find they have more patience than you think. If stress becomes a problem, consider speaking with a professional about that (e.g., through your University), or practicing meditation and mindfulness. Good luck!
