As far as alternatives go there is cozy cloud, which tbh I never tried, but it seems a lot more limited. Source: over 2 years ago

I use Cozy Drive. It's open source. You can pick a folder in your pc, and it syncs it to the cloud. You can still open in offline. They have 5gb free version, which I use, because I need it only for documents and photos. Android app is good too, and you can automatically sync your photos. Source: over 2 years ago

However, it really depends on one needs and usage. For example, tags might be a more flexible way to organize the passwords than folders, I agree with that. Searching in Bitwarden is reasonably good, which makes folders or tags a lot less relevant. The limited number of item types is not limited for my use, as I rarely use Bitwarden for anything else than managing passwords. Autofill never bothered me, personally.... Source: almost 3 years ago

If you want more of a web-based file sharing solution, you can try out more professionally made open source file sharing services like Syncthing, YouTransfer, or Cozy. The advantage of web-based solutions is that you can use them with your smartphone as well, which is very convenient. Source: about 3 years ago

From what I've seen of ProdPad it looks like an amazing piece of software, and one which I think would make my life as an aspiring product manager much easier - but it's very expensive. Source: almost 3 years ago
