J0y Information

J0y is the infrastructure for developers and AI agents building native data collection and visualization experiences—forms, PDFs, reports, surveys, e-sign flows, contracts, quizzes, and the growing catalogue of interface experiences that live in between. Nearly every modern product needs these experiences, and today teams build them the hard way: stitching together commercial tools, open-source libraries, hosted iframes, and custom code across web, iOS, and Android. We've learned from 8+ years in this space that these tools all share the same 80–90% core—and that rebuilding it over and over is one of the biggest hidden taxes on product teams. J0y replaces that work with: the .joy spec, a portable JSON standard that defines any interface from a single file; client-side SDKs that run natively inside your product across major platforms; and a managed platform for storage, generation, AI, and orchestration. One engine, many interfaces.
