I’ve wanted to offer file storage to family and friends on my homelab for a long time. But I was always hesitant. I didn’t want to have the ability to access their files. Even if I never would, the fact that I could bothered me and it bothered them too.

When I looked at self-hosted options, true E2EE turned out to be surprisingly rare. Most solutions rely on disk encryption, which only protects against physical theft, not server compromise or admin access.

So I built Agam Space, my attempt at a self-hosted alternative to Mega or Proton Drive. It uses proper zero-knowledge encryption. Files are encrypted in the browser, and the server only stores encrypted blobs. Admins literally cannot access the files.

It’s still in early beta, with very basic functionality and no professional security audit yet. Please don’t use it as your only backup.

The zero-knowledge architecture is crucial for this use case. One thing I've been contemplating while building PrivaVault (launching next week) is the tension between E2EE and search/organization features. Users need to find their documents quickly, but you can't build server-side search if you can't read the content.

We ended up implementing client-side encrypted search indices that sync across devices—adds complexity but preserves the zero-knowledge guarantee. Curious how Agam Space handles this? The demo looks clean, but I couldn't tell if search works on encrypted content or just filenames.
