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.

❓ Frequently Asked Questions

Common questions about ExtensionHub extensions, and more. View All →

How many extensions does ExtensionHub have?

ExtensionHub currently features 17 problem-focused extensions: Retail Trader Toolkit, Broker Compliance Suite, Amazon Wholesale Reseller Toolkit, Amazon Brand Protection Suite, International Trade Toolkit, Small Business & Freelancer Toolkit, Consumer Money & Shopping Toolkit, Real Estate Investor Toolkit, and Creator & Online Seller Toolkit, with new tools added regularly as we build toward 100+.

What's the difference between the two Amazon extensions?

The Amazon Wholesale Reseller Toolkit is built for sellers buying wholesale to resell — suspension appeals, invoice tracking, distributor terms. The Amazon Brand Protection Suite is built for the brand or manufacturer's side — catching unauthorized resellers, tracking authorization letters, and finding new distribution partners. Same platform, opposite side of the relationship.

Which extension has the most tools?

The Retail Trader Toolkit is the largest with 22 tools, covering stock and forex trading, execution auditing, and risk tools. Consumer Money & Shopping Toolkit comes second with 13, followed by Amazon Brand Protection Suite with 12.

Are all extensions on ExtensionHub free to use?

Every extension installs with a 14-day free trial that unlocks every feature. After the trial, core functionality keeps working for free indefinitely — a Monthly Pro subscription unlocks the deeper features across every tool. Pricing varies by extensions, from $5+/mo for consumer and solo-operator tools up to $99+/mo for business-facing compliance suites. Browsing the full directory is always free.

Do these extensions connect automatically to my broker, bank, or Amazon account?

No — by design. Every extension works from data you provide directly (manual entry, CSV import, or public data sources) rather than connecting to a live, authenticated session on your broker, bank, or Seller Central account. This avoids both a real security risk and a Terms of Service gray area that comes with automating access to accounts that hold your money or your business.

What's the difference between the Retail Trader Toolkit and the Broker Compliance Suite?

The Retail Trader Toolkit is for individual traders — loss limits, execution grading, FXCM calculators. The Broker Compliance Suite is a business tool for the brokerage itself — marketing compliance scanning, affiliate content monitoring, and multi-jurisdiction regulatory tracking. One serves the trader, the other serves the firm.

Are there extensions for Amazon sellers and FBA users?

Yes — 18 tools across two extensions. The Wholesale Reseller Toolkit (6 tools) covers suspension appeals, invoice authenticity, and distributor terms. The Brand Protection Suite (12 tools) covers unauthorized-reseller monitoring, MAP compliance tracking, and counterfeit evidence organizing — for the brand side of the relationship.

Can I use these extensions for trading and finance?

Yes — the Retail Trader Toolkit is our largest extensions at 22 tools, covering stocks and FXCM forex trading: Daily Loss-Limit Lockout, Personal Execution Quality Scorecard (NBBO), Wash Sale Rule Tracker, FXCM-Specific Margin & Instrument Calculator, and more, spanning day trading, swing trading, and scalping.

Are these third-party extensions, or built by ExtensionHub?

Every extension on ExtensionHub is built in-house, not sourced or aggregated from other developers. Each one follows the same design philosophy: solve exactly one problem well, rather than bundling unrelated features into an all-in-one app.

What data do these extensions actually collect?

Most tools run their calculations entirely locally in your browser — trade grades, margin calculations, pricing checks — with no server-side processing of your data. The only network call most extensions make is an optional license-key check against Gumroad for Pro features. Each extension's guide states plainly what it collects and where it's stored.

How is ExtensionHub different from browsing the Chrome Web Store directly?

The Chrome Web Store has thousands of general-purpose extensions competing on features. ExtensionHub is a single-developer catalog of narrow, single-job tools organized into problem-focused extensions, with one subscription unlocking every tool in that extensions — instead of hunting for, installing, and paying for a dozen separate all-in-one apps.

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.
