Social media by and for the people

Safety First

Basic safety features: mute, report, content warnings, and delete.

Scuttlebutt's "2 hops" algorithm restricts your view in most places to people you follow and the people they follow. This creates a safety net against spam and abuse that works similarly to social circles in the real world.

Instead of a single universal space, Nos helps create more scoped community focused social media.

Building a healthy commons together

Open Source, Open Society. Look under the hood at how Nos is built and roll up your sleeves to add to the app yourself.

Open Source

Nos and Nostr are open source. Transparency is real when you can read and modify the source code.
