A tiny, humble, and resource-efficient RSS reader.
Ketzel Pretzel is written by an eternal student at Stanford, completely from scratch in vanilla JavaScript with zero third-party dependencies. It is profiled and optimized to be responsive, never jank your browser, and handle thousands of feeds with minimal memory footprint. The extension size is just 12 KB.
Ketzel Pretzel is completely client-side with hardened security and privacy and no tracking, with a tight CSP, HTTPS autoupgrade, no-referer and no-opener policy for external resources. And you can use your cookies to access protected feeds, such as reddit, without giving away your credentials to a third party.
Both light and dark modes are supported.
The extension costs $29 as a one-time payment, with free updates included.
