Tools Coaster

Overview
Tools Coaster is a free toolkit with 500+ browser-based tools for developers, writers and creators: text tools, developer utilities, calculators, converters, SEO, color, security and network tools, with no sign-up.
The challenge
Everyday tools like JSON formatters, unit converters and calculators are scattered across ad-heavy sites that are slow, ask for sign-ups or upload private data.
