Overall verdict

  • Sing App React Java by Flatlogic is a solid, well-structured admin dashboard template that pairs a modern React frontend with a Java (Spring Boot) backend, making it a good choice for developers who want a ready-made full-stack starter kit rather than building an admin panel from scratch.

Why this product is good

  • Combines a React frontend with a Java/Spring Boot backend, giving a complete full-stack boilerplate out of the box
  • Includes pre-built UI components, charts, tables, and forms that speed up dashboard development
  • Clean and modern design that follows common admin panel UX patterns
  • Comes with authentication and basic CRUD operations already implemented
  • Good documentation and support from Flatlogic for setup and customization
  • Regularly maintained and updated to keep dependencies current
  • Affordable compared to hiring a developer to build a similar boilerplate from scratch

Recommended for

  • Developers who want a quick-start template for building admin panels or internal tools
  • Teams building SaaS products that need a Java backend paired with a React UI
  • Freelancers or agencies looking to speed up client project delivery with a pre-built dashboard
  • Startups wanting to prototype an admin interface without investing heavily in initial UI/UX design
  • Java developers who prefer Spring Boot but want a modern JavaScript frontend without building it themselves

Questions & Answers

As answered by people managing Klunivo and Sing App React Java.

Who are some of the biggest customers of your product?

Klunivo's answer

Klunivo is currently in its early commercial stage, so customer names are not yet publicly disclosed.

What makes your product unique?

Klunivo's answer

Klunivo combines the day-to-day operations of a sports club in one platform: members, parents and children, groups, schedules, memberships, payments, attendance, communication, documents, and events. It is designed around the real workflows of clubs running recurring group classes rather than being a generic CRM adapted to sports.

Why should a person choose your product over its competitors?

Klunivo's answer

Klunivo focuses on simplicity, practical automation, and the complete club workflow. Instead of managing schedules in one tool, payments in another, attendance in spreadsheets, and communication through messaging apps, clubs can manage everything from one system. It is especially well suited for organizations working with groups, memberships, children and parents.

How would you describe the primary audience of your product?

Klunivo's answer

Klunivo is built primarily for sports clubs and organizations running recurring group classes, typically with dozens or hundreds of members. This includes martial arts academies, BJJ and MMA clubs, dance schools, swimming schools, gymnastics and acrobatics clubs, football academies, Pilates and yoga studios, and other sports or activity-based organizations.

What's the story behind your product?

Klunivo's answer

Klunivo started after seeing the same operational problems repeatedly in sports clubs: unpaid memberships, manual payment tracking, schedules managed in spreadsheets, attendance recorded separately, documents scattered across different tools, and owners answering the same questions through WhatsApp and Messenger. The idea was simple: let coaches focus on coaching while the system handles more of the administrative work.

Which are the primary technologies used for building your product?

Klunivo's answer

Klunivo is built using a modern web stack including Next.js and React on the frontend, Node.js on the backend, PostgreSQL as the database, and Prisma for data access. The platform is deployed using Vercel and Railway and integrates with services such as Stripe and Resend.
