Most freelancers undercharge because they guess their rates instead of calculating them.

SoloHourly is a freelance rate calculator that helps you figure out what you actually need to charge based on your monthly expenses, income goals, and available working hours.

Instead of giving a generic estimate, it shows the gap between what you're charging and what you should be charging โ€” helping you avoid underpricing and unsustainable work.

No signup required. Simple inputs. Built for freelancers, not agencies.

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    The repository appears to be no longer actively maintained, with no recent commits or updates.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  • Outdated dependencies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

Overall verdict

  • SoloHourly appears to be a niche time-tracking and invoicing tool aimed at freelancers and solo professionals, but limited public information, reviews, and track record make it hard to fully verify its reliability, security, and long-term support compared to more established competitors.

Why this product is good

  • Focuses specifically on solo freelancers, offering a simpler, less cluttered interface than enterprise-focused time tracking tools
  • Likely includes core features like time tracking, invoicing, and basic client management tailored to independent workers
  • May offer competitive pricing for individuals compared to team-oriented software
  • Simplicity can reduce onboarding time for non-technical users

Recommended for

  • Freelancers who need straightforward time tracking without team collaboration features
  • Solo consultants or contractors looking for a lightweight invoicing solution
  • Users prioritizing simplicity over advanced integrations
  • Individuals testing basic time management tools before committing to more established platforms

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

SoloHourly's answer

SoloHourly is built using modern web technologies focused on performance and simplicity, ensuring fast calculations and a smooth user experience across devices.

What makes your product unique?

SoloHourly's answer

SoloHourly focuses on one core problem: freelancers undercharging.

Why should a person choose your product over its competitors?

Most tools give rough estimates or complex financial models. SoloHourly is built to be simple, fast, and practical.

It requires minimal input, gives clear output, and directly answers the most important question: โ€œAm I undercharging?โ€

No signup, no clutter, no unnecessary features โ€” just a focused tool for setting realistic freelance rates.

How would you describe the primary audience of your product?

SoloHourly is designed for freelancers, independent professionals, and beginners who struggle to price their work correctly.

It is especially useful for people transitioning from jobs to freelancing, where pricing is unclear and often underestimated.

What's the story behind your product?

SoloHourly's answer

SoloHourly was built after observing that many freelancers undercharge not because of lack of skill, but because they think in terms of hourly wages instead of business income.

The tool was created to shift that mindset by helping freelancers calculate rates based on real financial needs rather than guesswork.

Who are some of the biggest customers of your product?

SoloHourly's answer

SoloHourly is currently used by individual freelancers and independent professionals rather than large organizations.

The focus is on helping solo operators make better pricing decisions early in their journey.
