Previously I used free pr (it's not free because you invest your time) successfully, but wouldn't do it today. If you are with this project in the long run, I would do SEO (use tools like ahrefs): Find content that is relevant to your domain, look at sites who linked to that content and reach out to them offering them to link to your product or relevant blog post. FB, Insta, Reddit, HN, PH etc. are all places you can post your product once or twice. If you are testing the demand for your product, that might be enough (as long as your target market sees it). But if you are here for more than just testing, SEO is key imho. Good luck!
