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 SellWhere.app and Sing App React Java.

Which are the primary technologies used for building your product?

SellWhere.app's answer

  • Astro — static site framework for fast, SEO-friendly pages
  • React — interactive calculator components (Astro Islands architecture, so only calculators load JavaScript)
  • Tailwind CSS v4 — utility-first styling
  • Cloudflare Pages — global edge deployment for fast load times worldwide

What makes your product unique?

SellWhere.app's answer

SellWhere is the only free tool that lets you enter a sale price once and instantly compare your net payout across 6 major resale platforms — eBay, Poshmark, Mercari, Vinted, Depop, and Etsy. Most fee calculators only handle one platform at a time.

Our eBay calculator goes deeper than any competitor, modeling 20+ item categories, 6 store subscription tiers, and 3 seller levels. Every calculator shows when fees were last verified, with direct links to official fee pages so you can trust the numbers.

How would you describe the primary audience of your product?

SellWhere.app's answer

SellWhere serves two main groups:

  • Casual sellers clearing out closets or decluttering, who want to know which platform gives them the best payout before listing
  • Professional resellers who list across multiple platforms (eBay, Poshmark, Mercari, etc.) and need accurate, up-to-date fee comparisons to maximize their margins on every item

What's the story behind your product?

SellWhere.app's answer

SellWhere was born from a real frustration: resale platform fees are confusing, constantly changing, and scattered across different help pages. We wanted one place to see exactly what you'd take home on every major platform, with no guesswork.

Resale fees are also in a period of rapid change — Mercari dropped its seller fee to 0% in 2024, Depop eliminated buyer fees in mid-2024, and Vinted launched in the US in January 2026. Keeping up is hard. SellWhere was built to be the single source of truth for resellers navigating these shifts.
