Next-Router-State-Tree explorer

Soft-navigate between the routes below. The panel on the right intercepts every RSC fetch and decodes the Next-Router-State-Tree the browser attaches. Hard-load any URL — no fetch happens, so nothing is captured.

Dynamic route — segment [slug] = nicobar

Nicobar Pigeon

Caloenas nicobarica

IUCN status
Near Threatened
Mass
~600 g

The closest living relative of the dodo. Iridescent mane of hackles, white tail, nomadic across small islands of the Indo-Pacific.

The next outbound RSC fetch will encode [slug] as ["slug", "nicobar", "d"] in the state tree the browser sends. Click a different species and watch the right-hand panel: only that array's middle element changes between captures; the static parents stay put.
