Building a Serverless Social App with ATProto & Cloudflare Workers

In this episode, host João Tomé is joined by Inanna Malick, Systems Engineer at Cloudflare, to talk about how she built a serverless version of a real-time social app that connects to the ATProto ecosystem — the protocol powering platforms like Bluesky.

Inanna walks us through her blog post and technical journey, showing how she used Cloudflare Workers, Durable Objects, and the free tier of our Developer Platform to deploy an open, identity-owned, cryptographically verified social experience — all without running a server.

They discuss what makes ATProto different, how Statusphere works (the “Hello World” of open social apps), and what might be coming next in the world of decentralized platforms. Plus: how WebSockets and Durable Objects can be combined to create live, real-time updates — all running serverlessly.

Later in the episode, we check in with Keith Adler, Machine Learning Engineer, to hear how Cloudflare is making it easier to explore your data with Python notebooks powered by Marimo.
