chrome extension Coming soon
Cookiller
Delete a site's cookies in one click. That's it.
Developers and marketers clear cookies dozens of times a day — to test a signup flow, to see a page as a first-time visitor, to switch between client accounts. Chrome makes that four clicks and a settings page. Cookiller makes it one.

Why I built it
Every time I tested a newsletter signup or an onboarding flow I had to open settings, find the site, and clear it by hand. After the hundredth time I wrote the extension I wanted.
