Built with free tools. Designed for real learners. Ready for public deployment.

Two deployment modes

Demo mode and real-auth mode

SQL Ultimate supports two practical paths. Use the Demo Portal for zero-backend, fully static deployment. Use the Supabase Auth flow when you want real email/password accounts on the free tier.

Why this matters

Cost-conscious upgrade path

You asked for a practical system without AI API cost. This ultimate suite keeps that discipline while still offering an optional step up into real user authentication using free-tier infrastructure.

Course architecture

Organised tracks for different learner and institution needs

The platform is no longer only a general SQL learning site. It now includes a structured course catalog that supports absolute beginners, analysts, data scientists, BI learners, facilitators, and institutional rollout teams.

What the ultimate suite adds

Multi-page delivery, student portal, and admin mode

SQL Ultimate unifies the strongest parts of the earlier versions and extends them into a more complete suite: curriculum, playground, practice, capstones, demo portal, optional Supabase auth, teacher dashboard, lesson notes, certificates, and launch assets — all while staying within a free-tool architecture.

Choose your path

Designed for more than one kind of learner

Whether the user is aiming for analytics, data science, BI, or instructional use, the platform now clarifies how to approach the learning journey.

Portal experience

Student login and progress-friendly flow

SQL Ultimate includes a browser-based demo portal, optional Supabase auth, and teacher-facing support tools so the platform can serve both learners and delivery teams.

Cost strategy

Still free-tool and no paid AI API

This project remains intentionally free-tool focused. SQL execution still happens in the browser. Session logic still uses localStorage. Static deployment remains compatible with GitHub Pages, Cloudflare Pages, and Netlify.
