Wallabag. I switched from Pocket to Wallabag years ago because I didn't like sponsored content and ads in Pocket. I originally started paying for it as a subscription directly from wallabag.it, but then I started self-hosting it. Wallabag has an option to import all of your articles from Pocket too. It's a fantastic service.
After some researches I ended up with Wallabag as well, hosted on wallabag.it.
I've got a lot of things saved, sometimes quite long articles (I read a lot, but I save a lot more)
The ePub export was a requirement for me since I moved to Kobo (originally for the Pocket compatibility) after old Pocket app on my 1st gen iPad Mini stopped working.
I made some test to self host it but the epub export and the images caching was to much for my Synology NAS. I had some good results with a more powerful machine but I didn't want to keep it running 24/7.
And finally the export works well on wallabag.it so I though the hosted version worth its price!
I also switched to their hosted/paid offering and currently have no plans to self-host. I also aftee that the import tool from Pocket just worked and did a great job.
