Built the same way

Every Ninja app runs entirely inside your browser or Thunderbird. Your feeds, your books, your comics, your reading history. All of it stays on your machine. No accounts phoning home, no analytics watching what you read, no cloud service that can disappear tomorrow and take your library with it.

🔒

100% Local Storage

All your data lives in your browser's built-in storage. Feeds, books, reading progress, settings. Nothing is uploaded anywhere. If you clear your browser data, you control that too. It is your machine, your rules.

👁️

Zero Tracking

No analytics inside the extensions. No tracking pixels. No fingerprinting. We do not know what feeds you subscribe to, what books you read, or how often you open the app. That is how it should be.

🚫

No Algorithm

Nobody decides what you see except you. No engagement-optimised feed. No "recommended for you" nonsense. Subscribe to what you want, read it in the order it was published. Simple.

🌙

Dark & Light Themes

Full theme control across the entire browser chrome. One toggle changes everything. Matches your system preference or set it manually.

💾

Your Data Is Yours

Full import and export on every app. Bring your feeds from another reader with OPML. Export everything whenever you want. No lock-in, ever.

🖱️

Right-Click Menus

Context menus on everything. Mark feeds as read, star articles, jump to folders. Quick actions without hunting through menus or panels.

⌨️

Keyboard Navigation

Navigate chapters, articles, and folders without touching the mouse. Arrow keys, escape to close, shortcuts for everything. Power-user friendly from day one.

🚀

Actively Maintained

Regular updates and new features. Not abandoned. Built by an indie developer in the UK who uses these apps every single day.

🧹

No Bloat

No AI gimmicks. No social features. No recommendation engine. Each app does its job cleanly without trying to be something it is not.

Simple, friendly pricing

Why RSS Ninja?

Most reading apps want your data, your attention, and your money on repeat. RSS Ninja is different. Feeds, books, and comics in one private system that runs entirely in your browser. No cloud. No tracking. No algorithms deciding what you read. Just your content, your way. Built by an indie developer in the UK who believes you should own your reading experience. 🇬🇧
