I wouldn’t advise to do that. Back in 2022 I made the investment of throwing a MacMini in a corner of my appartment for the ONLY purpose of hosting DevonThink Server 24/7. Because I’m in the same situation as OP.
Do I get along with that? The web application up to this day offers a really, really bad user experience if you intend to use it for anything beyond finding your documents (which you’d like to do very likely if you’re a Windows User :)). I have to help my self out on a regular basis by accessing the Mac directly/via VNC and/or using the devon iOS App. Does it overly complicate things and blow up any satisfaction in neatly organizing your documents? Absolutely. Does it feel like I’m wasting valuable time and efforts to maintain a sketchy setup having all the negative impacts of physically hosting a server (hardware, regular electricity costs, $200 additional license costs, waste of physical space, risk of failure, damage and increased risk of fire, …)? Absolutely…
Is it worth it? No! After taking on all negative impacts and costs, the bad webapp is really the dealbreaker. It’s just pure disappointment. Some might disaggree, but I’m just not getting enough benefit out of it for the immense overhead. (And up to v3.9.4 Devon didn’t lift a finger to improve the web interface. I personally think that’s the least they could do for those who make this investment).
