What the columns mean

Next.js version: 16 is current. 14 is two major versions behind. App Router matured significantly between 14 and 16.

Auth: Auth.js v5 is the current standard with native App Router support. NextAuth v4 is legacy. Supabase Auth locks you into the Supabase ecosystem.

AI: Does the boilerplate include a working AI chat interface with streaming? In 2026, this is increasingly expected.

DB: Prisma + PostgreSQL gives maximum flexibility (deploy anywhere). Supabase locks you in. MongoDB is unusual for SaaS.

TS Strict: TypeScript strict mode catches entire categories of bugs at compile time.

Bottom line

ShipFast has the most social proof (Marc Lou built it). MakerKit has the most features (teams, organizations). LaunchKit has the newest stack and AI built in at the lowest price.

Pick based on your priorities: social proof, features, or modern stack.
