flatpass turns Discord roles into paid subscriptions. Members subscribe on your invite page, the bot assigns their role instantly, and the money lands in your own Stripe account โ€” not a platform balance you withdraw from later.

Flat pricing, never a percentage. Free up to 15 paid members. After that, a flat monthly tier metered on community size: $29 for up to 80 paid members, $79 for 200, $149 for 750, and uncapped for $399. Every feature is on every tier. The only thing that meters is active paid members โ€” flatpass takes 0% of your sales at any volume.

Your Stripe account stays yours. flatpass connects through Stripe Connect, using your own full Stripe dashboard โ€” you authorize from your own account and can revoke access anytime. Your customer data, payment history, and payment relationships stay with you. If you leave, you keep all of it.

Live in about ten minutes:

  1. Add the bot and set up Stripe โ€” sign in with your existing Stripe account or create one in about two minutes
  2. Pick a Discord role and set monthly or annual pricing โ€” your invite page builds itself
  3. Share your link โ€” members pay, the bot assigns the role, renewals and cancellations are handled automatically

Details

  • Cards, Apple Pay, and Google Pay enabled automatically through Stripe
  • Monthly and annual pricing, with multiple tiers per server
  • Built-in invite page analytics: visitors, page views, conversion rate, referral sources, and taggable campaign links
  • Members see local currency at checkout where Stripe supports it
  • Roles removed automatically when a subscription lapses
  • EU-based (Germany), works with Stripe accounts in any supported country
  • No setup fee, cancel anytime from your dashboard

Who it's for: communities that already have an audience. If you need a marketplace to find your first members, a platform with discovery may serve you better. If members are already coming to you, a percentage of every sale is rent on a storefront you aren't using.

React Engine features and specs

  • Isomorphic rendering
    React Engine enables both server-side and client-side rendering of React components, providing a seamless isomorphic/universal JavaScript experience. This allows for faster initial page loads and better SEO while maintaining rich client-side interactivity.
  • Express.js integration
    React Engine is designed as a view engine for Express.js, making it easy to integrate React into existing Express-based applications with minimal configuration. It follows familiar Express conventions for setting up view engines.
  • Built-in React Router support
    The library comes with built-in support for React Router, enabling developers to easily set up server-side and client-side routing without complex manual configuration.
  • PayPal backing
    React Engine was developed and maintained by PayPal, which provided credibility and ensured it was battle-tested in a large-scale production environment before being open-sourced.
  • Simplified setup
    The library abstracts away much of the complexity involved in setting up server-side rendering with React, reducing boilerplate code and allowing developers to get a universal React application running quickly.

Possible disadvantages of React Engine

  • Abandoned project
    The repository appears to be no longer actively maintained, with no recent commits or updates. This makes it risky to use in production as bugs and security vulnerabilities may go unpatched.
  • Outdated dependencies
    React Engine was built for older versions of React and React Router. It may not be compatible with modern versions of React (16+, 17, 18) or React Router (v5, v6), limiting its usefulness in current projects.
  • Limited ecosystem support
    The library is tightly coupled to Express.js, meaning it cannot be easily used with other Node.js frameworks like Koa, Hapi, or Fastify, reducing its flexibility.
  • Better modern alternatives
    Modern tools like Next.js, Remix, and Vite with SSR plugins provide far more comprehensive and well-maintained solutions for server-side rendering with React, making React Engine largely obsolete.
  • Limited documentation and community
    The project has relatively sparse documentation and a small community, making it difficult for new developers to troubleshoot issues or find examples and best practices for advanced use cases.

Analysis of React Engine

Overall verdict

  • Unable to verify a project specifically named 'React Engine' on GitHub with confidence, as this does not correspond to a widely recognized or well-documented open-source project that I have reliable information about. There may be multiple small or niche repositories using this name, and quality would vary significantly between them.

Why this product is good

  • React Engine is not a commonly recognized name in the mainstream React ecosystem
  • No verifiable consensus data on stars, maintenance status, documentation quality, or community adoption is available
  • Could refer to a personal project, a boilerplate, a rendering engine, or a niche tool - without more context, its quality cannot be assessed
  • Names like this are sometimes used for student projects, abandoned repos, or experimental tools that lack production readiness

Recommended for

  • Not recommended without further verification
  • Developers should search GitHub directly, check star count, last commit date, open issues, and documentation before adopting
  • Best suited for evaluation on a case-by-case basis rather than a blanket recommendation
  • If you have a specific repository URL, sharing it would allow for a more accurate assessment

Questions & Answers

As answered by people managing flatpass and React Engine.

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 โ€” 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 โ€” 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 โ€” never a percentage of your sales, at any volume.

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 โ€” 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 โ€” 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, annual billing, multiple role tiers per server, and a public status page. Every feature is on every tier โ€” nothing is held back for a higher plan.

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 โ€” 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 โ€” 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 โ€” 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.
