What stands out
A quick read of the recorded project description.
Built-in SSR landing page with login, registration, account buttons, and redirect after login
Provides examples of multiple user types (e.g., Admin, User) and their respective home pages
Includes table examples with server-side search, pagination, filtering, and sorting, plus a client-side paginated table example
Form examples synchronize server-side and client-side validation schemas and use react-hook-form
Comes with AGENTS.md and .agent/rules, targeting AI-assisted coding workflows
Template Details
blc-starter-next-b2c is a B2C SaaS project starter template maintained by BlackcurrantLabs, built with Next.js, using Prisma for data access, BetterAuth and BetterAuthUI for authentication, and Tailwind with Shadcn for styling and components. The template is positioned as a fixed combination of the author team's commonly used tech stack, and the README explicitly states that it may not suit all scenarios.
The template's built-in goals include: an SSR landing page with login, registration, and account buttons; static pages such as privacy policy and terms of use; favicon and robots.txt; multiple user types such as Admin and User with their respective home pages; an extensible authenticated API; page areas that are visible when logged out, visible after login, and visible only after validation via custom attributes (maker/checker model); table examples with server-side search, pagination, filtering, and sorting; a client-side paginated table example; and form examples with synchronized server-side and client-side validation. It also provides a JWT-based mobile API flow and runs long tasks via Trigger.dev with real-time status display on the frontend.
The repository includes AGENTS.md and .agent/rules, and the README states it is compatible with opencode, claude code, and antigravity, targeting so-called vibe code usage. If B2B scenarios are needed (users inviting collaboration within an organization), the README suggests switching to the B2B Starter repository from the same organization.
Runtime requirements are Node.js 22 LTS and pnpm 10.x. You need to copy example.env and fill in environment variables for database, authentication, email, and task queue. The tech stack table also lists Resend for email, Tanstack Tables for tables, react-hook-form for forms, and Context API for frontend state management. Deployment options include Vercel, Railway, or self-hosted AWS.

License & source material
Usage conditions & limitations
Free to use · keep license noticeThis entry covers the free version under the Apache-2.0 license in the public repository; the free scope is the code of that version and does not mean external services or third-party assets are free.
Must comply with when using
- Free use, modification, commercial use, and distribution are permitted; when distributing, the Apache-2.0 license must be included.
- Modified files must be prominently marked as changed, and relevant copyright, patent, trademark, and attribution notices must be retained.
- If the original project includes a NOTICE file, applicable attribution notices in it must be retained when distributing derivative works.
- The license includes an applicable contributor patent grant; initiating patent litigation as described in the license terminates that patent grant, and no trademark usage rights are granted.
- The code is provided as-is; warranties and limitations of liability are governed by the original license and applicable law.
Additional costs & items to verify
- The repository is positioned as a project boilerplate, not a ready-to-launch finished website; you need to customize development according to project requirements.
- The author explicitly states that this fixed tech stack combination may not suit all use cases; evaluate whether it matches your needs before adopting it.
- This template is only for B2C scenarios; if you need B2B features such as organizations and invitation-based collaboration within organizations, you need to switch to another B2B Starter repository from the same organization.
- Before use, you must copy example.env to .env and fill in all required environment variables, otherwise the project will not run properly.
- Email functionality depends on the third-party service Resend; you need to register an account and provide credentials such as RESEND_API_KEY, which may involve external service fees.
- Long task functionality depends on the third-party service Trigger.dev; you need to register an account and provide TRIGGER_SECRET_KEY, which may involve external service fees.
- You need to prepare and configure a database connection such as PostgreSQL (DATABASE_URL and other variables); database hosting or self-hosting costs are borne by the user.
- The runtime environment requires Node.js 22 LTS and pnpm 10.x; mismatched versions may prevent proper building or running.
- Demo images, fonts, icons, and other third-party assets must be checked against their respective licenses; you cannot judge solely based on the code's Apache-2.0 license.
- External services such as domain, hosting, database, payment, or AI may incur additional charges.

How this score is calculated
Our heuristic uses license records (up to 30), a demo link (12), a preview (10), stars (15), recorded maintenance (15), description completeness (8), feature records (5) and classification data (5). It is not a code, security or performance test, or a Google score. A link does not establish tested functionality.

A demo link is listed. Check it with your own content and viewport sizes; its presence does not confirm that forms, authentication or payments work.
The catalog identifies Next.js as the primary stack. Check the actual dependency manifest and lockfile for versions and hosting requirements. These notes use recorded metadata, not a code audit or a deployment test.
