Bluesky vs TikTok

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.

TikTok for Developers bundles several OAuth-based kits under one app registration — Login Kit for authentication, Display API for a user's own public videos, and Content Posting API for publishing on their behalf — all issued through open.tiktokapis.com. More sensitive scopes require TikTok's app review before going live, and a separate Research API exists for qualified academics to query public data.
