JBOX

JBOX is a coding tool that turns a plain-language brief into a hosted full-stack Next.js app. JBOX generates full-stack Next.js apps from a plain-language brief, mapping every screen, role and decision first, then building with Supabase, GitHub and built-in hosting.

JBOX is an AI product builder that turns a written brief into a working full-stack web application. Instead of generating isolated screens, it first maps the whole product: every screen, user role and decision point. The result is a connected set of user flows with backend logic, authentication and hosting attached, so the output behaves like a real product and not a visual mock-up. The workflow has three stages. A user describes what they want in plain language or pastes in an existing brief. JBOX then lays out every path for review, which lets founders, product managers and teammates check roles, screens and edge cases together before any code is produced. Once the map looks right, the build runs and the product can be opened, tested and published. The homepage example is a clinic platform with admin, clinician and patient roles, appointment booking and a billing dashboard, which shows the multi-role scope it aims at. Under the hood the build uses Next.js, Supabase, GitHub and JBOX Hosting. That stack matters for buyers who want ownership: the generated project can be exported as production code, and the work lives in a standard repository rather than a closed runtime. The site lists live projects built with it across health, fashion commerce, astrology, employer-of-record services, campaigning and real estate lending. The audience is non-technical founders validating an MVP, small teams who want to agree on product behavior before engineering starts, and developers who prefer to skip boilerplate. Pricing is credit-based: a free allowance to start, then paid credit packs without a subscription, plus a custom Enterprise tier with SSO and onboarding. Among alternatives, JBOX sits closer to prompt-to-app builders than to code assistants or UI generators. Its distinguishing choice is the planning step that exposes missing paths early, trading some speed for a more complete first build. Teams wanting free-form editing inside an IDE, or stacks other than Next.js and Supabase, may find it narrower than general coding tools.
