  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing RoomCalcs and Nullstack.

Which are the primary technologies used for building your product?

RoomCalcs's answer

Next.js and React with TypeScript, styled with Tailwind CSS. The site is exported as static pages and hosted on Cloudflare Pages, so it is fast and works on any device. Three.js powers the 3D tile visualizer, and jsPDF creates the downloadable PDF lists. All calculations run in the browser, and every calculator is covered by automated tests that check it against hand-worked and published values.

Why should a person choose your product over its competitors?

RoomCalcs's answer

Most calculator sites cover one material at a time, ask for one unit only and hide how they got the answer. RoomCalcs has 44 building and renovation calculators in one place: tiles, grout, flooring, paint, wallpaper, drywall, concrete, bricks, roof tiles, gravel, pavers, decks, stairs, floor joist spans and more. They all work the same way, so you learn it once. Results come in whole packs to buy (boxes, bags, tins, rolls) with a spare allowance, not just a bare number. You can save everything to one project list. Local sizes are built in, such as UK, US, German, Dutch and Pakistani bricks, Euro wallpaper rolls and 50 kg cement bags. There is no account, no paywall and no email required.

What's the story behind your product?

RoomCalcs's answer

RoomCalcs started in 2026 from a simple frustration: working out materials for a room meant jumping between different calculators, each asking for a different unit and none showing its formula. The goal was one free site where any measurement works in any box and every answer can be checked. It launched in October 2026 with tile, paint and concrete calculators, and grew from what people actually search for: a floor joist span calculator, epoxy floor and heated floor calculators, and "per m²" tables for common materials. It is now available in four languages.

How would you describe the primary audience of your product?

RoomCalcs's answer

Homeowners and DIYers planning a renovation who want to know how much to buy before going to the shop. Also small builders, tilers, painters and landscapers who need a quick estimate for a quote, and students learning building calculations. Most visitors come from the US, the UK, Germany, the Netherlands, France and Pakistan.

Who are some of the biggest customers of your product?

RoomCalcs's answer

  • Homeowners and DIYers planning renovations
  • Small building and renovation contractors
  • Tilers, painters and flooring installers
  • Landscapers and garden DIYers
  • Students of construction and civil engineering

What makes your product unique?

RoomCalcs's answer

Every box takes any unit. You can type 3' 4 1/2", 1.02 m or 40 cm, mix them, and the results show metric and imperial side by side. Each calculator also shows its formula, a worked example and the sources it is based on, so you can check the maths yourself. Many pages have ready-made "per m²" and "per 100 sq ft" tables worked out by the calculator. There is a 3D tile visualizer and a photo room designer, and you can add prices and download a PDF or spreadsheet shopping list. It is all free, with no sign-up, in English, German, Dutch and French.
