Bluesky is built on the AT Protocol, a decentralized social networking protocol. Link card data is fetched by a service called CardyB and then baked permanently into the post record, making Bluesky’s caching model fundamentally different from every other platform.
This guide covers how CardyB crawls your pages, which tags Bluesky reads, image compression requirements, the immutable caching model, and the most common issues that prevent cards from displaying correctly.
