I recently switched from Pocket to a self-hosted instance of Wallabag (https://wallabag.org) and I've been very happy with it.
One thing I've noticed with these types of services is that they quickly start becoming intrusive and annoying. Ads are the obvious annoyance. But as an additional example, the Pocket extension injects code into certain sites (HackerNews being one) so that I can "more easily" "pocket" posted articles directly from the listing page itself. And in fairness it can be disabled, but it's enabled by default. And with things like this, I just find that simpler is better. I don't need all these extra features being pushed and modifying my browsing experience "by default".
