Jbox is an AI product builder that turns a plain-language brief into a connected, full-stack Next.js web app, complete with screens, roles, data, authentication and hosting.
You describe what you want to build, or paste in a brief. Jbox then maps every screen, role, decision and handoff so you can check them together before the build starts. Once you are happy, you open the connected product, test it and publish.
It generates complete, multi-role product flows with screens, logic and edge cases. An example on the site is a clinic platform with admin, clinician and patient roles, appointment booking and a billing dashboard.
Key features include plain-language or pasted briefs as input, a review of screens, roles and decisions before development, connected user flows with backend logic and authentication, live hosting and export to production code.
The screens, roles and decision points are mapped and reviewed before the build starts, so you can check how the whole product fits together first. The finished product is hosted and live, and the code can be exported if you want to take it further yourself.
It is built on Next.js and integrates with Supabase, GitHub and Jbox Hosting.
Pricing: the self-serve Jbox Pro plan starts at $0 with 50 credits included, with no credit card and no subscription required. More credits cost $20 per 100. An Enterprise plan with custom pricing adds custom credit allocation, SSO, onboarding and dedicated support.
It is suited to product managers, founders, developers and CTOs, and to non-developer professionals who want to turn an idea into a working web product.
