Atmosphere Account
The last social account
you’ll ever need.
One account for all your apps. Yours to keep, wherever you go.
What is the Atmosphere?
The Atmosphere is a new open network of apps and services that all work together. Instead of every app being its own walled garden, Atmosphere apps share a common foundation — so you only need one account to use them all. You might have heard of Bluesky — that’s the first Atmosphere app, but there are many more. Anyone can build one, and new ones appear every day.
Your Atmosphere Account is your passport to this entire ecosystem. One account unlocks every app — no more creating new logins, no more losing your stuff when you switch. Sign in once, and you’re home everywhere.
The Atmosphere isn’t owned or controlled by any single big-tech company. This isn’t just another “Sign in with Google”, it’s an open social web.
Of course, you can have multiple accounts if you want — great for keeping different personas separate. Whatever you choose, every account you own works across the entire Atmosphere.
Everything in one place.
All your stuff — from every Atmosphere app you use — lives in your one Atmosphere account. Sign in anywhere, pick up right where you left off.
A few examples — there’s no fixed list. New apps bring new kinds of data, all in one place.
Built different.
Universal identity
One login across Atmosphere apps, and the same @handle everywhere — so when someone mentions you, it’s the same you, recognized across the network.
You own your account
Your data isn’t trapped in any one app. Unlike traditional social accounts, where your profile and content belong to the platform, an Atmosphere account puts you in charge — you genuinely own your identity and your data.
Anyone can build
Developers can build new apps on the Atmosphere and tap into an existing network from day one.
Great for personal websites
Your @handle can be your own domain. Your identity, your brand — no handle squatting.
Choose your account host.
Your Atmosphere account lives with an account host — a service that stores your data in your personal data storage and keeps it available across every app. That host might be an app you already use, or a service that only holds accounts. You pick who hosts your account, and you can switch any time.
Apps such as Bluesky are also account hosts. When you sign up, they create an account for you and host your data. Some apps are only apps: you sign in with an account hosted somewhere else.
Independent account hosts are not apps themselves; they only hold your account and data. A growing number of them offer Atmosphere accounts: some are community-run, some focus on privacy or geographic location.
Technical users can host their own account. Full control over your data, on your own infrastructure. The Atmosphere is open — anyone can host an account.
Your handle travels with you
Your host can show up right in your handle.
By default, your handle ends with your account host, like @you.bsky.social or @you.sprk.so. If you have your own domain, you can use that instead, like @you.com.
No matter which account host you choose, your account works everywhere and you can move to a different host at any time — no data lost.
Post once, show everywhere.
Your content flows freely across every app in the Atmosphere.
These are just examples. The Atmosphere is open — any app can create and surface any kind of content. The possibilities grow with every new app that joins.
Your account, your choice.
No single company decides what you see, who you follow, or where you go. Everything is yours to control.
Moderation
Subscribe to community-built moderation — labels, filters, and block lists made by the people who understand the problem best. Don’t like an app’s rules? Layer on your own, or switch apps entirely.
Algorithms
Feeds are open — anyone can build one. Switch between them like playlists: friends-only, indie art, slow news, or something deeply niche. No single algorithm quietly decides culture for everyone.
Portability
Move between apps and hosts while keeping your connections, posts, and followers — no more starting over. Creators can leave an app without losing their audience; your followers are yours, not rented from a platform.
Account ownership, moderation, and algorithmic choice — the system is locked open by design.
