ToolSparkr Reviews — Discover what people think of this product.

ToolSparkr is a free collection of 35+ browser-based developer tools I built as a solo indie dev. JSON formatter, Base64 encoder, password generator, QR code creator, color converter, UUID generator, hash generators, DNS/WHOIS lookup — all in one place. No signup. No data uploaded. PageSpeed 100/100. Open source on GitHub. Built because every "free tool" site was either slow, full of ads, or required registration.
