Browser security for developers

About PasteGuard

PasteGuard is built to stop exposed API keys, tokens, and private keys before they leave the browser. It checks risky pastes, form fields, and browser workflows at the moment a developer can still prevent the leak.

Our mission is to make secret protection practical in everyday work: clear warnings for individuals, shared safeguards for teams, and stronger controls for organizations that need auditability.
