  • Automatic role assignment
    Members pay, the bot grants their Discord role instantly. A buyer who isn't in your server yet is added with it. No manual verification.
  • Automatic role removal
    The role comes off when a subscription ends, is refunded or charged back. It stays while Stripe retries a failed renewal.
  • Hosted invite page
    A subscription page in your server's own look (name, icon and colours) builds itself from your roles and pricing. No code.
  • Price card in Discord
    Post a card in any channel and pin it: each plan gets a button with its price, and the card updates when you change one.
  • Checkout links
    Every plan has its own link that opens checkout directly, for your website, bio or anywhere else you post.
  • Invite Page Analytics
    Visitors, page views, clicks on your checkout links and conversion rate, by referral source, region and device, plus taggable campaign links to track individual shares.

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

  • 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

  • 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

Questions & Answers

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

What makes your product unique?

flatpass's answer

flatpass is built on the premise that the payment relationship belongs to you, not the platform.

Payments settle into your own Stripe account through Stripe Connect Standard. Not a platform balance you withdraw from on someone else's schedule — your account, your balance, instant settlement, no rolling reserves or minimum payout thresholds. Your customers, their payment history, and your ability to email them are yours from the first sale. Revoke the connection whenever you like and you keep every bit of it.

Everything else follows from that. The invite page is a real hosted checkout, not a bot DM — members see your tiers, pay with cards, Apple Pay, or Google Pay in their own currency, and get their role instantly. Renewals, failed payments, and cancellations are handled without you touching anything.

And because flatpass isn't processing your money, it doesn't need a cut of it. Free up to 15 paid members, then a flat monthly tier metered on community size — never a percentage of your sales, at any volume.

How would you describe the primary audience of your product?

flatpass's answer

Discord community owners who already have an audience and are monetizing access to it — trading and investing groups, creator and fan communities, coaching and cohort programs, professional and industry servers, gaming communities with supporter tiers, and study or skills groups.

The common thread is that members are already arriving through the owner's own channels: a following, a mailing list, a podcast, an existing free server. These owners don't need discovery — they need billing and role management that doesn't scale its price with their success.

flatpass is free up to 15 paid members, so it costs nothing to start — and past that, a flat tier replaces a percentage that would otherwise grow with every sale. It's built for owners who want to keep the Stripe account, customer data, and payment relationship in their own hands rather than on a platform. EU-based, with sellers in any country Stripe supports.

Why should a person choose your product over its competitors?

flatpass's answer

Your Stripe, not a platform balance. Several competitors mention Stripe, but the account is often theirs. With Stripe Connect Standard the account is yours — instant settlement, no rolling reserves, no withdrawal fees, and the customer relationship stays with you if you leave.

No API keys. flatpass authorizes through Stripe Connect Standard — an OAuth grant you approve in your own Stripe dashboard and revoke there in one click. Some Discord payment bots instead ask you to paste your Stripe secret key into their dashboard. That key is unscoped: it can charge, refund, read your entire customer list, and change payout details, and the only way to revoke it is to rotate it. Stripe's own guidance is not to share secret keys with third parties. flatpass never asks for one and has nothing of yours to leak.

A product that feels finished. A hosted invite page rather than a bot DM flow, local-currency checkout, monthly, quaterly, six-monthly or yearly billing, with multiple role tiers per server, and a public status page. Every feature is on every tier — nothing is held back for a higher plan.
