Capture cookies from any tab and apply them to another — ideal for switching between environments like production and localhost. Credentials Changer is a developer tool for managing browser cookies across environments. Instead of opening DevTools and manually copying cookie values one by one, just save a named credential profile with the cookies you care about and apply them to any tab in one click. Use cases: Switch between production and localhost without logging in again Test different user sessions quickly Share session state between tabs Privacy: All credentials are stored locally via Chrome's storage API. No external requests are made.
