I built stack127 while working on my own projects. I kept needing practical tools and clear references for the same questions: SaaS metrics, Amazon KDP royalties, domain records, storage, and platform fees. stack127 brings those tools and resources together so other indie hackers, solo developers, and digital creators can use them too. Most of the tools are open source through stack127labs on GitHub.
