About this category
Developer Tools
Developer utilities are where privacy matters most, because the payload is often an API response containing tokens, customer records or internal URLs. Every tool here executes in your browser's own JavaScript runtime. There is no request body to log, no proxy to trust and no retention window to read about — close the tab and the data is gone.
