I Built 22 Chrome Extensions to Solve Problems Everyone Complains About

…and Yes, I’m Going to Tell You They’re Great

Full disclosure: I made these things. Objectivity left the building. Buckle up.

Let me be upfront with you before we go any further.

This article is about ExtensionHub.app — a collection of 22 Chrome extensions I personally built, and I am going to spend the next several minutes telling you they are wonderful, useful, life-changing, and probably the best thing to happen to your browser since tabbed browsing was invented.

Is this objective journalism? Absolutely not.

Is this a sponsored post? No, I am literally the only person involved.

Is this just a founder talking about their own products with completely unearned confidence? Yes. Exactly that. You’ve spotted it. Well done.

Now that we’ve cleared the air — let me tell you about the very real, very annoying problems that made me build these, and why I think they might actually be worth five minutes of your time.

The Problem Nobody Is Actually Solving

Here’s the thing about the modern internet: everyone builds everything for everyone.

You want a browser extension that does one small thing? Great. Here’s a bloated all-in-one app that does 47 things, half of which you’ll never use, all of which require permissions it has no business requesting.

You want a tool for your specific problem? Good luck finding it in a sea of “everything-but-the-kitchen-sink” solutions that:

• Track your browsing history
• Sell your data
• Require 15 permissions
• Look like they were designed in 2005
• Cost $30/month for features you don’t need

I’ve watched this conversation happen dozens of times on Reddit, Twitter, LinkedIn, Hacker News — you name it. Someone posts “is there an extension that does X?” and the responses flood in with remarkable consistency:

“Just use [bloated all-in-one tool].”

Sure. Or I could use something that actually does exactly what I need and nothing else.

“Why not just do it manually?”

Beautiful. Love the enthusiasm. Will look into spending 20 extra minutes every day doing something a computer should do for me.

“Just use the built-in browser feature.”

I’m going to pretend you didn’t say that. The built-in browser feature doesn’t exist, doesn’t work, or is buried so deep in settings that nobody can find it.

Here’s the thing that frustrated me most: every problem I was solving already had a solution somewhere. The math was public. The methodology was documented. The API was right there in Chrome. But nobody had packaged it well.

Someone had built the thing for themselves. Someone else had built a half-broken version. Someone else had built something that did 50 other things and one of them vaguely resembled what I needed.

So I stopped waiting.

What ExtensionHub Actually Is

At its core, ExtensionHub is simple: 22 single-purpose browser extensions, each solving exactly one real problem well.

No bloat. No unnecessary permissions. No tracking. Just a tool that does the thing it says it does, and then gets out of your way.

The extensions are organized into categories:

📊 Finance & Trading (4 extensions)

Scope-creep tracking, vendor contract scanning, merchant processing fee auditing, 1099 threshold tracking. Finally, a way to prove that “just one small thing” was never part of the original scope.

Shrinkflation tracking, fake-discount verdict scoring, coupon-stacking calculators, warranty tracking. Instead of a confusing price chart, it gives you a plain verdict: “this sale price is actually 8% higher than the 90-day average.”

DevTools for AI Coders → Try it now

Capture full page context for AI prompts. Stop copy-pasting snippets — send the entire context to your AI coding assistant with one click.

Find Japanese fonts on any page. If you’re learning Japanese or working with Japanese content, this is a lifesaver.

Recipe Ingredient Cross-Checker → Coming soon.

Build your shopping cart from recipes. No more “I think I have flour” guessing games.

The Features I’m Particularly Proud Of (Remember: Not Biased At All)

🎯 One Problem, One Tool

Every extension does exactly one thing. The Retail Trader Toolkit doesn’t try to be your Amazon seller dashboard. The Amazon Brand Protection Suite doesn’t try to manage your freelance contracts. Each tool is narrow, focused, and built for one specific job.

This might sound obvious. It’s not. Most extensions try to do everything and end up doing none of it well. My approach is different: build the exact tool for the exact problem, and make it work perfectly.

🔒 Local-First Privacy

Most extensions run entirely in your browser. The only routine network call most tools make is an optional Pro license check via Gumroad. No data leaves your browser. No tracking. No selling your browsing history.

When I started building these, I looked at what other extensions were asking for and was honestly alarmed. Full history access. All websites. Data collection. For a tool that just needed to read your tabs.

So I built things differently. If an extension doesn’t need a permission, it doesn’t ask for it.

💡 Transparent Methodology

Every extension’s calculations are based on public, documented sources. SEC execution-quality rules. FXCM’s own contract specs. IRS thresholds. OFAC’s public screening list.

Nothing is a black box. You can see exactly how the math works. If you don’t like the methodology, you’re free to disagree with it. But you’ll never have to wonder “where did this number come from?”

⏱️ Free Core, Forever

Every extension keeps its core features free after the 14-day trial. Pro subscriptions unlock deeper features per extension.

I believe the basics should be free. If the tool solves your problem with the free features, great. If you need more power, the Pro subscription is there. No tricks. No hidden fees.

The Honest Part

Here’s where I step slightly outside my self-promotional fog and talk to you straight.

I’m a solo developer. Everything on ExtensionHub is built, designed, and tested by me. This means:

• Updates might be slower than a team of 20 developers
• Some extensions are newer and less polished than others
• There are 22 extensions today, and I’m working toward 100+

If something breaks, I fix it. If you have a feature request, I read it. If the UI is ugly, I’m working on it.

But here’s what it also means: every extension is built with care. Not because I’m trying to meet a quarterly target, but because I use these tools myself. The Retail Trader Toolkit? I use it. The Consumer Money Shopping Toolkit? I use it. I built these because I needed them, and then I made them good enough for other people.

Are there tradeoffs? Yes.

• Memory Hub estimates memory usage — it doesn’t measure it exactly. Chrome doesn’t let extensions do that.
• The sanctions screener is a screening aid, not a legal compliance guarantee.
• Some extensions are newer and have fewer features than others.

And yes, you might already have a solution that works for you. Chrome has built-in memory saving. Your brokerage has its own calculators. Amazon has its own brand registry.

If you’re happy with what you have, you might not need these.

If you want more control, more transparency, and more information, that’s what ExtensionHub is for.

Why I Built This Instead of Just… Writing a Blog Post About It

Because I’m a builder. And I’m allergic to problems that have known solutions that nobody has packaged well.

I had 50 tabs open one afternoon. My machine was slow. I looked at the various tab manager extensions available and found them mostly outdated, mostly ugly, or mostly asking for permissions they had no business requesting.

I had a tax problem. I looked at the available tools and found nothing that worked the way I needed.

I had an Amazon seller problem. I looked at the available tools and found bloated, expensive, enterprise solutions for a small seller problem.

So I built things. Not all at once. One problem at a time.

The first extension was for me. The second was for a friend. The third was for a frustration I’d been carrying for years. After a while, I realized I had a collection of tools that other people might actually want.

So I cleaned them up, made them work consistently, and put them in one place.

No grand origin story. No venture funding. Just a series of problems I had, solutions that existed in pieces, and the specific kind of stubbornness that makes people build things at 1 am on a Saturday.

Try Them. Or Don’t. But Probably Try Them.

ExtensionHub is free to start. Every extension has a 14-day free trial with full Pro features. After that, the core features stay free forever.

Permissions are minimal. Most extensions need only: tabs (to see your tab URLs and titles), storage (to save your settings), and sometimes windows (to focus the right window). No host permissions. No content scripts. No data leaves your browser.

If it doesn’t help you, uninstall it. No hard feelings. My feelings are, objectively, extremely fine.

But if you’re someone who’s been nodding along to this article because yes, the internet is full of problems that should have been solved by now, and yes, you keep having to cobble together half-solutions from different places — give ExtensionHub ten minutes.

Browse the directory. Find the extension that matches your problem. Install it. See if it works.

Then go tell someone about the specific problem it solved. You’ll have a better answer for them.

ExtensionHub is available now at extensionhub.app

Works on Chrome, Brave, Edge, and any Chromium-based browser.

P.S.

I told you at the start I wasn’t going to be objective. I kept that promise. You’re welcome.
