I faced the same issue, but I wanted to use my Kindle to read RSS feeds without relying on my PC, phone or Amazon, so I built a FOSS web-based RSS reader compatible with the Kindle browser. It may make your life a lot simpler.
Hello Adham! Great solution, but I'm having an issue using my Paperwhite 7 Generation in the Kindle web browser. When I try to click on any of the already saved feed, a pop up appears showing the following: loadFeed error: 'undefined' is not an object.
Maybe you have already encountered an issue like this.
Thanks in advance!
It's hard for me to debug this because I don't have a Paperwhite 7. I assume it's a JS compatibility issue but not where the exact root cause.
Since the reader is Open Source, can you run it on your machine and view it on your local network to debug and tell me what's the issue so that I can fix it?
On Kindle 7’s outdated WebKit, both feed loading and article opening failed because the code relied on Set and DOM properties(too modern) that were missing, causing “undefined is not an object/function” errors.
I could fix it by adding defensive null/type checks across DOM and helper functions, and implementing a full Set polyfill (has, add, delete, clear, forEach) to ensure compatibility without changing the existing logic.
Now that I'm checking, the Hacker News articles don't correctly load. Only shows the URL.
It would be great if you opened an issue on GitHub (or a PR) so we can fix this. I definitely want this to work on all Kindles including older models. Thank you.
I haven't open sourced the Backend yet, but the reader frontend repo is fully working without the Backend. The Backend is used for emailing yourself and doing file conversion on the Backend instead of the Kindle to save battery.
So without the Backend you're only missing the email feature. All you need is a proxy to bypass CORS.
To be honest I was thinking of keeping the Backend closed source to add subscriptions ($1 per month) to cover the hosting (4$), which means I only need 4 users to break even haha.
Will think about open sourcing the Backend and get back to you.
Why Jailbreak the Kindle when you can just open its browser and visit a website that shows the arrival times?
The Kindle browser is surprisingly decent, I made Claude Code generate an RSS feed reader compatible with the Kindle browser, with the ability to read full articles (for those feeds that require you to visit the website), and download articles. It also supports Reddit and Google News RSS feed. This is my new favorite way of browsing the internet.
Bricked it few times in the process of figuring out more stuff about it, but luckily mine has a UART pads and I was able to restore it every time. A bit more involved as it's 1.8V if I remember right, but if you're careful it should be easy, provided you have the time.
it will be much less power-efficient, when jailbreak you could schedule the kindle to wake up once per 15/30/60 minutes to fetch the new data, set it as screensaver and then go back to sleep.
At no point in human history has C been the best language for beginners. C was, like Javascript, hacked together in a weekend by someone who wished they could be using a better language. It was burdened with flaws from the outset and considered archaic in its design almost immediately. The best thing that can be said about the design of C is that it's at least a structured programming language, which is damning with faint praise.
