Built for Privacy. Engineered for Accuracy.
Tulzu is a high-performance ecosystem of 50+ free online tools designed to solve daily technical, financial, and creative problems without ever compromising your data.
Our Mission
Most online utilities today are cluttered with trackers, require sign-ups, or process your sensitive data on distant servers. Tulzu was built to be different. Our tools run 100% client-side, meaning your calculations, JSON payloads, and photos never leave your device.
