Why choose SFS

Everything you need for file sharing, ready to use.

Your own environment, automatically

Within minutes of signing up, you get your own dedicated Nextcloud and URL (yourname.sfs.sola.inc). An isolated environment, never shared with other companies.

Hosted in Japan

All data is stored on our own servers in Japan, designed and operated by Sola — a company where 80% of staff are engineers.

Unlimited users

No extra charge no matter how many people use it. Pricing is based on storage alone — simple and predictable.

Secure external sharing

Set expiry dates, passwords, and download limits on share links. Exchange files with clients and partners safely.

Two-factor authentication

One-time-code two-factor authentication is built in, so you can strengthen account protection from day one.

Use it anywhere

Access from your browser, the Windows/Mac sync client, or the official Nextcloud iOS/Android apps.
