FileDue is a payment-gated file delivery tool for freelancers and small studios. Users upload final deliverables, set a price, and share a secure delivery link with a client. The client pays through Stripe before the files unlock for download.

It is built for designers, developers, writers, photographers, video editors, translators, and other freelancers who deliver digital work to clients. FileDue helps freelancers move payment into the delivery step instead of sending files first and chasing invoices later.

There is no subscription. The first 3 paid links are free, then FileDue charges 2% per paid link.

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    The repository appears to be no longer actively maintained, with no recent commits or updates.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  • Outdated dependencies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 FileDue

Overall verdict

  • I don't have reliable or verified information about a service called FileDue at filedue.com, so I can't confirm its legitimacy, features, or quality. Before using it, I'd recommend independently verifying the company's reputation, checking reviews on trusted third-party sites, confirming security certifications, and reading their terms of service and privacy policy carefully.

Why this product is good

  • Insufficient verified data available about this specific service to make a fair assessment
  • Unable to confirm company legitimacy, ownership, or track record
  • No access to independent reviews, security audits, or user feedback for this platform

Recommended for

  • Not applicable due to lack of verifiable information
  • Users should research independently using trusted review platforms, WHOIS lookups, and security scanners before proceeding
  • Consider well-established, widely-reviewed alternatives if file storage or sharing services are needed

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 FileDue and React Engine.

What makes your product unique?

FileDue's answer

FileDue combines file delivery and payment into one workflow. Instead of sending files first and chasing payment later, freelancers upload deliverables, set a price, and share one secure link. The client pays through Stripe, then the files unlock for download.

The core difference is timing: payment happens before final access.

Why should a person choose your product over its competitors?

FileDue's answer

Most file-sharing tools help freelancers send files. FileDue helps freelancers get paid before those files are released.

It is a good fit when the deliverable itself has value: design files, source code, photo galleries, video exports, documents, translations, or other finished client work. Clients do not need a FileDue account, payments are handled through Stripe, and files stay locked until checkout is complete.

How would you describe the primary audience of your product?

FileDue's answer

FileDue is built for freelancers, solo operators, and small studios that deliver digital work to clients.

The primary audience includes designers, developers, writers, photographers, video editors, translators, and other service providers who send final files and want payment to happen before download.

What's the story behind your product?

FileDue's answer

FileDue started from a common freelance problem: clients receiving final deliverables and then delaying or disappearing when it is time to pay.

The idea is simple: change the order. Instead of sending files first and hoping an invoice gets paid later, freelancers send a payment-locked delivery link. The client pays first, and the files unlock automatically.

Which are the primary technologies used for building your product?

FileDue's answer

FileDue is built as a modern web application using Next.js, React, TypeScript, and Stripe Connect for payments.

File storage uses Cloudflare R2 with EU and US region options. The product is hosted as a cloud-based SaaS application.

Who are some of the biggest customers of your product?

FileDue's answer

FileDue is an early-stage product and does not publicly list customer names yet.
