Blog

Development stories, build logs, and practical tips for everyone.

The SudoTool blog is where we share the stories behind our tools, practical guides for everyday digital tasks, and insights from building and running a small web project. Posts are written for both developers and non-technical readers.

We write about what we're building, what we've learned, and what we think might be genuinely useful to you. Topics range from beginner-friendly explanations of technical concepts to behind-the-scenes development stories. Whether you're a seasoned developer or someone who just wants to understand the tools you use online, you'll find something relevant here.

New posts are published regularly — bookmark this page or check back whenever you're looking for something to read.

Why I Built a Pomodoro Timer When Hundreds Already Exist
Most Pomodoro timers are either too simple or too complex. I built one with immersive backgrounds, ambient sounds, and Flowtime mode — a focus space you want open all day.

Why I Built a Password Generator When Hundreds Already Exist

Why I Built a Free QR Code Generator When "Free" Ones Already Exist
Every "free" QR code generator charges for colors, logos, and SVG downloads. I built one where every feature is actually free and nothing leaves your browser.

Why I Built a World Clock and Meeting Planner When Phone Apps Already Exist
Your phone can tell you what time it is in London. It can't tell you when London, Seoul, and New York are all awake at the same time. So I built a tool that does.

Why I Built a Browser-Based Image Compressor When Free Ones Already Exist
Free compressor sites have usage limits, skip WebP, and store your files on their servers. So I built one that runs entirely in the browser — no upload, no server, no limits.

Weather apps show you the day. They don't tell you whether Monday at 6 AM is actually a good time to run. Here's why I built a tool that does exactly that.

What We Write About

Our blog covers a range of topics centered around the tools we build and the things we learn along the way:

  • Dev Logs — Behind-the-scenes posts about how we build and maintain SudoTool. From infrastructure decisions to design choices, we share the process openly.
  • Guides — Practical, beginner-friendly explanations of technical concepts related to our tools. If you've ever wondered what Base64 encoding actually is, or why JSON looks the way it does, these posts are for you.
  • Tips — Short, actionable posts about tools, workflows, and everyday digital tasks. We focus on things that save you time and reduce frustration.
  • Behind the Build — Longer-form posts about the decisions that shape SudoTool: why we chose certain technologies, what we got wrong, and what we'd do differently.

All posts are written to be accessible to everyone, not just developers. If you have a topic you'd like us to cover, let us know.

Who This Blog Is For

SudoTool's blog is written for a wide audience. You don't need to be a software developer to get value from it. Many of our guides are specifically written for people who use digital tools every day but don't have a technical background — things like how to understand an encoded URL, what a hash function does, or how to read a JSON file.

For developers, we also go deeper: walking through the technical details of how each tool works, what edge cases to watch out for, and how you can use these utilities in your own workflows. Whether you're copy-pasting something into a formatter or building a pipeline that calls an encoder, we try to give you context that's actually useful.

How We Approach Writing

Every post on this blog goes through the same editorial check: is it clear, is it accurate, and does it add something genuinely useful? We don't publish posts just to fill space. We write when we have something worth saying.

We avoid unnecessary jargon, but we don't dumb things down either. If a concept is inherently technical, we explain it with real examples rather than glossing over the details. Our goal is for every reader — regardless of their background — to finish a post feeling like they actually learned something.

We also take accuracy seriously. If we make a mistake in a post, we update it and note the correction. The web has enough outdated technical content; we'd rather publish less and get it right.

Stay Updated

There's no newsletter or feed subscription right now — just check back when you want to read something new. We'll be publishing posts consistently as the site grows.
