Free tools for SaaS founders

A small, honest toolkit for people building SaaS on a real budget. No signups, no email walls, no fluff — just tools that answer a specific question fast: is my page leaking signups, what does my industry actually convert at, what's a redesign worth, and does my headline make sense? Built by a 0-to-1 SaaS design partner, so they lean toward the things that quietly move conversion. Pick one and go.
