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 Omnivaleur and Sing App React Java.

What's the story behind your product?

Omnivaleur's answer

Omnivaleur started from a reseller's own frustration: typing the same listing again for every marketplace, and forgetting to remove an item that had already sold. It was built to fix that first for Marktplaats and 2dehands, then extended to Vinted, eBay and Shopify.

What makes your product unique?

Omnivaleur's answer

Omnivaleur supports Marktplaats and 2dehands, the biggest secondhand marketplaces in the Netherlands and Belgium, next to Vinted, eBay and Shopify. No other crosslisting tool does. It also translates every listing per platform and tracks real profit per item.

How would you describe the primary audience of your product?

Omnivaleur's answer

Resellers of secondhand goods in Europe, especially in the Netherlands and Belgium. Typical sellers deal in vintage and secondhand clothing, jewellery and antiques, and list on two or more marketplaces at the same time.

Which are the primary technologies used for building your product?

Omnivaleur's answer

Python with FastAPI on the backend, Supabase (PostgreSQL) for data, a Chrome extension that publishes to the marketplaces from the seller's own browser, Cloudflare R2 for photos, Stripe for payments and Resend for email.

Why should a person choose your product over its competitors?

Omnivaleur's answer

Most crosslisting tools are built for the US market and skip Marktplaats and 2dehands. Omnivaleur was built for European resellers. It imports your existing listings, removes sold items from all other channels automatically, renews expiring listings and works at a calm pace that looks like a human seller. It costs EUR 19.99 per month for up to five channels, with a 7 day free trial.
