# DarkNOC Org — open agent registry > Open registry of DarkNOC agent toolboxes, simulators, scenarios, and operator config shapes. > Built on the Reality Twin. Schema-first, machine-readable, openly fetchable. ## Open JSON feeds (recommended for agents) - [Toolbox registry](https://darknoc.org/api/registry.json): all agent toolboxes, with filters and TMF API bindings - [Simulator registry](https://darknoc.org/api/sims.json): the 10-sim constellation, the cascade, and scenario index ## On this site - [/](https://darknoc.org/): filterable toolbox grid (44+ agent concepts, 132 TMF APIs) - [/apis](https://darknoc.org/apis): catalogue of TMF API tools - [/sims](https://darknoc.org/sims): the 10-simulator constellation + cascade - [/scenarios](https://darknoc.org/scenarios): DOIL-scripted cross-sim scenarios - [/operators](https://darknoc.org/operators): multi-tenant operator config shape (synthetic example only) - [/live-ops](https://darknoc.org/live-ops): the cockpit, running ## Three surfaces - [darknoc.net](https://darknoc.net): showroom — story, screenshots, diagrams - [darknoc.org](https://darknoc.org): open registry (this site) - [darknoc.dev](https://darknoc.dev): toolkit — DOIL language, compiler, wizard, VSCode extension, notes ## Reality Twin (the framing) A Reality Twin closes the loop a digital twin only mirrors. Signals in → models in the middle → agents acting back out. Canonical post: [darknoc.dev/blog/reality-twin](https://darknoc.dev/blog/reality-twin) ## Voice DarkNOC is an open concept exploration. No commercial framing. No customers, no pricing, no plans.
