next-js-boilerplate
A clone-and-edit Next.js App Router starter in TypeScript with Tailwind CSS 4, Clerk authentication, and Drizzle ORM on PostgreSQL (PGlite locally, Neon suggested for production). It also wires in next-intl i18n, Vitest, Playwright, Storybook, Sentry, LogTape and Arcjet. It includes no AI features beyond agent instruction files and CodeRabbit review.

- Auth depends on a hosted Clerk account and API keys
- No billing; Stripe, teams, RBAC and shadcn UI are in the paid Pro kit
- No built-in AI features such as chat or model calls
- Many sponsor-linked services (Sentry, Arcjet, Crowdin, Better Stack) to configure or strip out
- TypeScript
- Needs Node.js 24+, npm, Clerk, PostgreSQL (PGlite locally, Neon optional), Sentry, Crowdin, Arcjet
- GitHub template

velobase-harness
A Next.js 15 and tRPC application with Prisma on Postgres and BullMQ on Redis that already has accounts, subscriptions, a credit ledger, Stripe and NowPayments, entitlement checks, affiliate accounting, server-side attribution, anti-abuse controls (rate limits, Turnstile, disposable-email checks), lifecycle email, an admin area and a multi-provider AI chat module. One command starts Postgres and Redis in Docker. For builders turning an AI prototype into a paid product.

- Seed shows 607 stars; young project
- TypeScript, ai-sdk, openai, anthropic, google
- Needs postgres, redis, docker, stripe, model-api-keys
- GitHub template
- Docker
- env example file
