CollateKit
Free, private, browser-based text & dev tools — no sign-up
What is CollateKit?
CollateKit is a free, growing suite of browser-based text and developer tools — think JSON formatting, regex testing, Base64 encoding, UUID generation, and more. Everything runs 100% client-side, so nothing you type or paste is ever uploaded, tracked, or stored. No sign-up, no ads blocking the workflow, just fast tools that work instantly. Built for developers, writers, and students who want reliable utilities without friction or privacy trade-offs.
