"ato de yomu" (means "read it later" in Japanese) is a read-it-later app where you can save web pages to read later, track your reading history, and share your lists—or keep them private.

You can add pages to your list not only through the website but also via API requests. Plus, there’s support for the iOS Share Sheet and Alfred Workflow.

It is open-source: https://github.com/morishin/atodeyomu.morishin.me

I hope you find it useful!
