Next.js + Supabase SaaS starter with an AI template variant

Best for: Next.js + Supabase developers who want an AI-flavored SaaS template with a live demo to evaluate before buying.
Skip if: You want a Postgres provider other than Supabase, or a lower entry price than $199.

useSAASkit is a paid Next.js starter built on Supabase, with a specific AI-focused template variant available as a live demo. Ships the usual SaaS baseline (auth, billing) on top of Supabase's Postgres backend. One-time purchase starting at $199.

Pros

A live demo exists for the AI template variant, so you can evaluate the actual product rather than screenshots alone.
Supabase-based stack gives you Postgres, auth, and storage from one provider.
Positioned specifically for AI-flavored SaaS, a growing niche this site tracks separately from general SaaS kits.

Cons

No public repo to inspect before buying - the demo shows the UI, not the code quality.
This listing is built from a single source page - independent reviews and freshness were not separately verified.
$199 entry price is mid-to-high for this category without a visible free/lower tier.
