What stands out
A quick read of the recorded project description.
Integrates Supabase authentication and PostgreSQL data access, and includes storage policies and browser-side image compression examples
Integrates Stripe Checkout, customer portal, and webhooks to synchronize pricing plans and subscription status
Uses TailwindCSS and shadcn/ui components, with Zod for data validation
Includes Jest, React Testing Library, and Playwright testing tools, plus ESLint, Prettier, Husky, and Commitlint development standards
Documentation and blog use Fumadocs' MDX compiler, and the README also provides tRPC integration guidance
Template Details
Hikari is published on GitHub by coremvp under the MIT license and is positioned as a starter template for SaaS subscription applications. It uses the Next.js App Router and pre-builds common SaaS modules such as user authentication, PostgreSQL data access, Stripe Checkout and customer portal, and subscription status synchronization, and includes pages for pricing, dashboard, documentation, and blog. The README explicitly notes that the project is still in public development (work in progress), so features and structure may continue to change.
The template's UI layer is based on TailwindCSS and shadcn/ui components, uses Zod for data validation, and integrates testing tools such as Jest, React Testing Library, and Playwright, as well as development standards tools including ESLint, Prettier, Husky, and Commitlint. The documentation and blog sections use Fumadocs' MDX compiler. The README also mentions Supabase storage policies and browser-side image compression, tRPC integration guidance, local Supabase and Docker development commands, Paraglide internationalization support, and the need to archive Stripe test products and switch to production environment variables before redeploying for launch.
Using this template requires preparing external services such as Supabase and Stripe yourself, and these services may incur costs; the licenses for third-party assets such as demo images, fonts, and icons must be verified separately.

- 1
The README notes that the project is still in public development, so features and structure may change; check the repository's latest status before use
- 2
You must prepare Supabase and Stripe accounts yourself and configure the corresponding environment variables; these external services may incur costs
- 3
Before launch, archive Stripe test-mode products, switch to production mode, update environment variables, and redeploy
- 4
The licenses for third-party assets such as demo images, fonts, and icons must be verified separately and cannot be determined solely from the code's MIT license
- 5
Local development involves Supabase, Docker, and custom commands provided by the repository; refer to the official Quick Start documentation for specific steps
License & source material
Usage conditions & limitations
Free to use · keep license noticeThis entry covers the free version under the MIT license in the public repository; the free scope applies to that version's code and does not mean external services or third-party assets are free.
Must comply with when using
- You may use, modify, commercialize, and distribute this version's code for free.
- When distributing copies or substantial portions of the code, retain the original author's copyright notice and the complete MIT license notice.
- 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 project is still in an ongoing public development state, so features and structure may change at any time, and it is not guaranteed to be stable or production-ready.
- Before launch, you must archive Stripe test-mode products, switch to production mode, and update environment variables; otherwise subscription billing will not work properly.
- Authentication and data management depend on the external Supabase service, which requires registering an account and configuring it yourself and may incur costs.
- Subscription billing depends on the external Stripe service, which requires opening an account and configuring API keys yourself and may incur costs.
- Local development requires Docker and a Supabase environment and depends on custom commands provided by the repository, so environment setup has some barriers.
- Demo images, fonts, icons, and other third-party assets must be verified under their respective licenses and cannot be determined solely from the code's MIT license.
- External services such as domains, hosting, databases, payments, 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.
