Tools that solve real problems

It Started with Frustration

There is a particular kind of frustration that comes from needing a simple tool online and instead finding yourself wading through pages of ads, mandatory signups, and paywalls for features that should be free. I have been there more times than I can count. I needed to check whether a domain name was available, and every site I visited wanted me to create an account before showing me a result. I wanted to generate a quick QR code for a business card, and the tool demanded my email address before letting me download the image. These moments piled up over the years, and eventually I decided to stop complaining about it and start building alternatives.

That is the origin of yanni.uk. It is not a startup pitch or a venture-backed platform. It is one person's ongoing effort to create free online tools that actually respect the people who use them. Every tool on this site works without signup, runs without intrusive advertising, and does exactly what it says on the label. No bait and switch, no freemium tricks, no dark patterns nudging you toward a subscription you never wanted.

Making Technology Accessible to Everyone

The internet was built on the idea that information and tools should be accessible. Somewhere along the way, that principle got buried under monetisation strategies and growth hacking. I believe that the best web tools are the ones that get out of your way. If you need to generate a QR code, you should be able to visit a page, paste your link, hit a button, and download the result. The whole interaction should take less than thirty seconds. That is the standard I hold every tool on this site to. If it takes longer than it should, or asks for more than it needs, then I have failed at my job.

This philosophy extends to how the tools are built technically. Wherever possible, processing happens directly in your browser. Your data stays on your device. There are no server logs recording what domains you searched for or what text you put into a QR code. Privacy is not a feature I bolt on as an afterthought. It is a constraint I design around from the very beginning. When you use web tools with no signup required, you should genuinely be anonymous, and on this site, you are.

The Art of Solving Everyday Problems

I spend a lot of time thinking about the small problems that eat up people's time throughout the day. A developer needs to test a regex pattern but does not want to install a desktop application for something so trivial. A small business owner wants to create a professional-looking QR code for their shop window without hiring a designer. A student is researching domain names for a university project and just wants straightforward availability data without being funnelled into purchasing flows. These are not glamorous problems. No one writes breathless blog posts about them. But they are real, they are common, and they deserve good solutions.

My approach to building online utilities is to start with the problem and work backwards. I do not begin with a technology and go looking for something to apply it to. Instead, I ask a simple question: what is annoying me right now, and can I fix it with a clean interface and a few well-chosen APIs? The result is tools like DomainScout, which pulls together domain availability data so you do not have to bounce between five different registrar websites. Or QRForge, which gives you a fully customisable QR code generator that runs entirely in the browser. Or CodeBench Pro, an online code compiler supporting dozens of languages so you can quickly test a snippet without setting up a local development environment.

Building for People, Not Metrics

One of the things that sets this project apart from the average collection of productivity tools free on the web is that I am not optimising for engagement metrics. I do not want you to spend more time on this site than necessary. I want you to arrive, solve your problem, and leave. If a tool is well built, the best compliment it can receive is that the person who used it barely thought about it. They came, they got what they needed, and they moved on with their day. That is success.

This means I do not clutter interfaces with upsell banners or newsletter popups. There are no exit-intent modals begging you to stay. The tools are designed to load fast, work reliably, and present a clean interface that anyone can understand within seconds. Whether you are a seasoned developer or someone who has never written a line of code, the experience should feel intuitive. I test every tool across devices, from wide desktop monitors down to small phone screens, because a tool that only works on a laptop is not really a free online tool in any meaningful sense.

The Power of API Mashups

Many of the tools on this site are built using a technique I think of as API mashups. Public APIs are incredible resources. There are APIs for checking domain availability, for generating QR codes, for compiling source code, for fetching weather data, for analysing colour palettes, and for thousands of other tasks. Individually, each API solves a narrow problem. But when you combine them thoughtfully, layer a well-designed interface on top, and handle the edge cases that trip people up, you get something genuinely useful. You get free developer tools and everyday utilities that feel polished and complete.

This is the creative part of what I do, and honestly it is the part I enjoy most. Taking two or three APIs that were never designed to work together and weaving them into a single seamless experience feels like a kind of digital craftsmanship. The user should never have to know that behind the scenes, their request is hitting multiple services and the results are being merged and formatted in real time. All they should see is a fast, clean answer to their question. That abstraction of complexity into simplicity is what I aim for with every tool I build.

An Ongoing Project

Yanni.uk is not a finished product. It is an evolving collection, and I add new tools as I identify problems worth solving. The roadmap includes utilities for colour palette generation, receipt scanning, font pairing, Markdown editing, API health monitoring, and much more. Each tool goes through the same process: identify a genuine pain point, research the best APIs and approaches, build a clean interface, test it thoroughly, and ship it. I would rather have ten excellent tools than a hundred mediocre ones.

If you have found a tool here useful, that is all the reward I need. If you have an idea for a tool you wish existed, I am always open to hearing about it. The best online utilities come from listening to what people actually need rather than guessing from behind a screen. This site is built for you, the person who just wants to get something done without jumping through hoops. I intend to keep it that way.

Every tool, every feature, every design decision on this site comes back to the same principle: technology should make your life easier, not harder. If a domain checker requires three clicks to show you a result, it should not require four. If a code compiler online can run your snippet in under a second, it should not make you wait five. These are small things individually, but they add up to an experience that feels respectful of your time. That is the standard, and I am not interested in compromising it.
