[WTB] - SaaS with MRR

Hello! I am looking to buy a small SaaS. My budget is 5k, but would lean towards less. I would like to either have MRR or a decently sized user base.

I am a seasoned dev and would like to do a code review before purchasing.

Interested in dev tools, but open to all kinds. Feel free to DM me
