   SEO Stuff▲614

   Hi HN! My name is Yossi, and I'm a solo indie maker. SEO tools are super pricey and free tools often fall short, leaving most users to costly subscription-based tools. So, I built SEO Stuff, a keyword tool that uses a credit-based system for builders like me who use SEO more sporadically. Have a great day!
