I built Stoolzen to solve a simple problem: developers constantly switch between multiple tools just to format, validate or debug data. JSON formatters, JWT decoders, regex testers and similar utilities are scattered across dozens of sites, many of them slow, cluttered or full of ads. Stoolzen brings these essential tools into a single fast, clean and privacy-focused interface. The goal was not to reinvent these tools, but to make them significantly faster, more consistent, and easier to use in real development workflows. Would love feedback on what tools are missing or what would make this more useful in daily dev work.
