Just a casual dev

I built Free Tools Library because the free tools I kept finding wanted an account, a download, or my files. All 52 tools here run in your browser, so your files never leave your device. I also wanted tools that fit Nigeria — a PAYE tax calculator and an NGX stock and dividend calculator covering all 146 listed stocks — alongside the everyday tools I use myself. Thank you for trying it, and I would love your feedback on which tools to add next.
