Periscope

Periscope is a web content reader that removes popups, ads, and annoyances, providing a clean and distraction-free reading experience.

It has a simple interface that fetches web content while applying custom rulesets to improve reading experience.

Why make another one?

All of the existing ones are great (see comparison below), but the most powerful one is Ladder, because it has a domain-specific ruleset system. This means each website can have its own custom rules - for example, using specific request headers to properly fetch content from certain websites, rather than just using simple techniques like fetching raw HTML or spoofing the user agent as Googlebot.

While Ladder is self-hosted, Periscope provides these same powerful capabilities as a hosted service, making it more accessible to everyone.
