Blogger vs Bluesky

Blogger API v3 is Google's REST/JSON interface for its blogging platform, letting apps retrieve and manage blogs, posts, comments, and pages. Public data can be read with a plain API key, but writing content or touching private data requires a full OAuth 2.0 authorization flow. The docs still list the deprecated v1.0 and v2.0 protocol guides alongside the current v3.0 reference, reflecting a mature, low-churn API that hasn't needed a v4.

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.
