Real, citable facts about Claude Apps -- Claude.ai's Artifacts-based apps surface.
Claude Apps are interactive, AI-powered mini-apps built through conversation with Claude and published from the Artifacts space in Claude.ai -- no coding required. Every fact this site catalogs was pulled directly from a live fetch of an Anthropic-owned page this session (not from training-data memory), and every row keeps its exact source_url so any claim here can be checked against the original.
Every row's source_url is a real page fetched this session -- claude.com/blog/build-artifacts, its companion tutorial, and Claude Code's Agent SDK overview for the differentiation angle.
Apps run on Anthropic's infrastructure; a published app's usage counts against each viewer's own Claude subscription, not the creator's.
Claude Apps are Claude.ai's no-code, chat-driven artifact surface. The Agent SDK is the programmable engine developers embed in their own applications -- a different product for a different audience.
