I settled on Raindrop.io which is free but I paid to support it ($30 a year I think). I had to change my workflow slightly and the Obsidian integration is not as great as Omnivore’s, but it wasn’t a pain. The browser integration is really good and I prefer it to Omnivore’s. It supports RSS and has a decent mobile app.
Overall I think it’s a decent replacement and I’m happy.
I tried Wallabag but the Obsidian integration was poor and Wallabag felt unloved recycle by extension made me question it’s future (which is unfair given my limited time with it). There was a trial which was not enough time for me to evaluate it comfortably.
I use pfSense and tried to migrate away in the past. The changes I would have had to make to setup opnsense were so significant that I gave up for to lack of time. I don’t have time luxury of downtime so I need to migrate quickly.
But if I were starting again I’d absolutely avoid the pfSense project and their childish shitty behaviour.
I do plan to buy more hardware to replace my current pfSense box and take my time to implement opnsense gradually.
