Build modern TypeScript applications with one cohesive toolchain. Nitrogen brings together Lex for project workflows, GothamJS for React 19 interfaces, ArkhamJS for predictable state, MetropolisJS for typed API integration, and Reaktor for application services—each with complete documentation and a focused developer experience.
We built Nitrogen because modern TypeScript projects often require stitching together disconnected tools with different conventions. The Nitrogen Developer Stack gives teams one coherent path from creating a project to building its interface, managing state, connecting APIs, and delivering backend services. We would love feedback from developers on the individual libraries and the stack as a whole.
