KumikiA web framework of AI, by AI, for AI

Definitions interlock like Japanese joinery (kumiki) — no JSX, no Hooks, no hidden state — so AI can write, edit, and reassemble an app in parallel. Experimental.

Spec

7 layers

type / slot / effect / reducer / tile / fn / app. State, side effects, and UI are split by role, with no implicit rules.

Easy for AI to edit in parts

Each definition is independent and references are explicit. The CLI and MCP server provide per-definition list / view / add / replace / fix.

Measured ease of learning

Cross-vendor confirmed that multiple LLMs can write 1300-line-scale apps from the spec alone.

Answers everything with working examples

Comprehensive per-feature minimal examples and apps ordered by size. Questions and bugs are answered by adding an example and a test.
