Bluesky vs Facebook

Bluesky is the decentralized social network built on the AT Protocol, where posts, follows, and identity live on portable Personal Data Servers instead of one company's database. Its public AppView at public.api.bsky.app exposes keyless, read-only XRPC methods such as app.bsky.actor.getProfile and app.bsky.feed.getAuthorFeed, so any client can pull public profiles and feeds without registering an app. Posting, following, or reading a signed-in user's private data instead requires an authenticated session against a Personal Data Server via an app password or OAuth, not a single global API key.

Meta's Graph API is the single HTTP interface behind Facebook Login, Page management, and Social Plugins, exposing versioned endpoints under graph.facebook.com that read and write data about people, Pages, and Groups once a user grants OAuth permissions. Most scopes that touch another person's data or a business Page require Meta's app review process before they work outside development mode, and the same Graph API infrastructure also underlies Instagram's Business API stack.
