The ExtensionHub.app Standard

HOW EVERY EXTENSION IS BUILT

🧪

Experience

Every extension is designed, built, and personally tested by one founder before it ships, and the library continues to grow with new tools added regularly.

🎯

Expertise

Every calculation is documented in a full guide showing the exact formula and worked example — nothing runs as an unexplained black box.

🏛️

Authoritativeness

Formulas are sourced from primary authorities, not guesswork — SEC Reg NMS execution-quality methodology, FXCM's own published contract specs, IRS thresholds, and OFAC's public screening list.

🛡️

Trustworthiness

Most tools run entirely in your browser with no server-side processing of your data. Pricing, data handling, and limitations are stated plainly in every guide.

🔒 SSL Encrypted 📖 Sourced & Documented 🆓 Free Core, Forever 🏗️ Built In-House 📅 Updated Weekly 📈 Actively Growing

👋 About Me — Muhiuddin Alam

Hello, I'm Muhiuddin Alam — an independent developer and the builder behind ExtensionHub.app, a growing library of single-purpose Chrome extensions for trading, Amazon selling, international trade, small business operations, and everyday consumer finance.

I build and maintain ExtensionHub.app, where every extension is built in-house, organized into problem-focused extensions, and the catalog continues to grow with new tools added regularly.

You'll also find my writing on:

Based in New York, I design, build, and test every extension myself before it ships — each one is built around a single job: solve one specific problem well, with transparent, verifiable calculations rather than a black box.

🌐 About ExtensionHub.app

Single-Purpose Browser Extensions • Built In-House • Trading, Selling & Everyday Money Tools

ExtensionHub.app Logo

ExtensionHub.app is a single-developer library of Chrome extensions, organized into problem-focused extensions, with new ones added regularly. Every extension is built in-house—not sourced or aggregated from other developers.

I am Muhiuddin Alam, the developer behind ExtensionHub.app. My approach is simple: build narrow, single-purpose tools that solve one specific problem well, instead of bundling unrelated features into a bloated all-in-one app you'll only half use.

Each extension is built around a real, specific audience — retail and forex traders, Amazon wholesale sellers and brand owners, import/export businesses, freelancers and small business owners, everyday shoppers, real estate investors, and content creators. Every extension shares one subscription, so you're never paying separately per tool.

Here's how every extension on ExtensionHub.app is actually built:

  • 🎯 One job each — every extension solves exactly one problem, with no bundled feature creep.
  • 🧮 Transparent calculations — formulas are based on public, verifiable methodology (like the same NBBO execution-quality math brokers use, or FXCM's own published contract specs), not a black box.
  • 🔒 Local-first data — most extensions run entirely in your browser with no server-side processing of your data; the only network call most tools make is an optional license check for Pro features.
  • 💵 Free core, forever — every extension keeps its core features working for free after the 14-day trial ends. Only the deeper Pro features require a subscription.

From trading and risk tools to Amazon wholesale and brand protection, international trade compliance, small business operations, and everyday consumer finance — each extensions was built around a specific, real gap I found wasn't already well-served by existing tools.

With ExtensionHub.app, you install exactly the tool for the problem you actually have, understand exactly what data it collects (usually none beyond what stays in your own browser), and pay for one extension's Pro subscription instead of hunting down and paying for a dozen separate apps.
