AT Protocol Powers Over 30 Open Social Web Apps
A year after its public launch, Bluesky has amassed over 36.5 million users on its AT Protocol network. The first ATmosphere conference in Seattle united developers building dozens of interoperable, consumer-facing apps—from photo and video sharing to livestreaming, blogging, and more—all designed to foster an open, decentralized social web. Early projects like Flashes and Streamplace showcase this ecosystem’s potential.
A New Era for Open Social Networking
Just one year ago, Bluesky broke out of private beta and positioned itself as a challenger to traditional social networks. Today, it boasts over 36.5 million users leveraging the AT Protocol (ATProto) to share updates, host media, and connect across a decentralized ecosystem.
In late March 2025, developers from dozens of AT Protocol–based applications gathered in Seattle for ATmosphere. Whether attending in person or tuning in online, they explored the road ahead for ATProto, tackled remaining technical hurdles, and collaborated on building a truly open social web.
The AT Protocol Ecosystem Unfolds
ATProto powers a growing network of consumer-facing apps that interoperate seamlessly. From photo-sharing to live video, each project taps into an open stack rather than siloed infrastructure—putting control back into users’ hands and sparking innovation across the social landscape.
Spotlight on Emerging Apps
AN OVERVIEW OF CONSUMER-FACING CATEGORIES
- Photo & Video Sharing – Innovators like Flashes, Spark, and Pinksky are building Instagram and TikTok alternatives on ATProto.
- Livestreaming – Streamplace delivered high-quality, cryptographically signed live streams from the ATmosphere conference.
- Feed Builders – Tools like Graze and Surf let users craft custom feeds across Bluesky, Mastodon, RSS and more.

Charting the Road Ahead
With dozens more apps under development—ranging from events management to analytics, blogging to gaming—the AT Protocol ecosystem is evolving faster than ever. What if social networks were built on open standards, not walled gardens? The ATProto community is proving it can be done.
