In my search for the ultimate read-it-later-workflow I have since long ended up with Wallabag. It is open source, integrates beautifully with KOreader to read on my e-reader, and most importantly: it’s the only service that properly deals with the messy cookie walls that DPG Media, the owner of pretty much all Dutch newspapers, set up. The only downside? The apps are terribly ugly. The iOS app seems to be somehow fully native while at the same time managing to mess up each UI element. The web app offers a choice between two themes which were both designed in their own historic epochs of web design.

Enter ReadKit. I have been using the app on iOS for years. It has a beautiful but simple design that is very faithful to iOS. It supports almost every RSS service out there (including the soon to be deceased but still lovely Feed Wrangler) and it supports Wallabag. It’s just the ultimate frontend to Wallabag’s wonderful backend. Until now however its Mac equivalent had a totally different and outdated codebase and didn’t even support the same services.
Until now, because ReadKit has just launched version 3.0 as a universal app on the macOS App Store. I would say it is every bit as beautiful as its iOS counterpart, but it honestly even looks better. It’s the most Mac-like app on my Mac that was not made by Apple. It has sharesheet support, which lets me save web articles straight from Safari to Wallabag. It allows for plenty of customization, so you can tailor it to your own reading preferences. But honestly, it’s already pretty as it is.
Isn’t it pretty?
The only downside is that it doesn’t offer highlighting support, which is probably not on them as I guess it’s not supported by the Wallabag API, but otherwise it really is the perfect RSS and read-it-later app.
