No Coin

No coin is a tiny browser extension aiming to block coin miners such as Coinhive.

Trusted by thousands of users, No Coin provides you a safe and reliable way to block miners from using your CPU and power without your consent. It features an easy way to allow miners for a limited time in case you need to pass a captcha or shortlink requiring mining.

No Coin is also open source and licensed under MIT. Feel free to view the source, fork it, raise issues and submit your improvements via pull requests. You can find on Github:
