Building free web tools and calculators

About

I build free, no-signup web tools, currently working on Toolstack (everyday utilities and calculators) and a Sun/Moon/Rising astrology calculator. Always looking for feedback on what's useful and what's missing.

Toolstack - 20 free online tools, no signup required

A free collection of 20 everyday web tools, calculators, PDF tools, image tools, text tools, and converters. Everything runs instantly in your browser: compress a PDF, generate a password, check word count, calculate your BMI, and more. No signup, no account walls, no watermarks, built because most "free" tools online still make you jump through hoops before you get to the actual tool.
