Nextbase

Next.js + Supabase SaaS starter with an Entity Builder and CRM bundle

Best for: Next.js + Supabase developers who want an Entity Builder for fast CRUD scaffolding, and don't mind paying more for CRM/feature-flag add-ons.
Skip if: You don't need CRUD scaffolding tooling specifically - a simpler kit may cover your auth/billing needs for less.

Nextbase is a Next.js and Supabase SaaS starter from Bhargav Ponnapalli, known for an Entity Builder feature that scaffolds CRUD resources with permissions and webhooks, plus optional CRM and feature-flag bundles at higher tiers. Sold as a one-time purchase starting at $99.

Pros

The Entity Builder (CRUD scaffolding with permissions/webhooks) is a genuinely distinctive feature versus typical auth+billing-only kits.
Independently noted in prior research for this site as having best-in-class documentation among Supabase-based kits.
$99 entry price is reasonable, with optional paid add-ons (CRM, feature flags) rather than everything bundled at a higher forced price.

Cons

The core Entity Builder feature and the CRM/feature-flag bundles are separate purchases - read the tier breakdown carefully before assuming everything is included at $99.
The site returned a rate-limit response (HTTP 429) during this review's reachability check - likely bot protection rather than the site being down, but worth a manual check.
No public repo to inspect code quality before buying.
