Find answers to common questions about each of our 9 problem-focused categories — from Retail Trading to Creator Tools.
Our largest category with 22 extensions covering stock and forex trading — daily loss-limit enforcement, execution-quality grading against the NBBO, FXCM-specific margin and swap calculators, wash sale tracking, and tools for day trading, swing trading, and scalping specifically.
Set a daily dollar or percentage loss limit once, in a calm moment, and the extension physically blocks your trading platforms the instant your logged losses hit it. Hard-lock mode has no override until your next scheduled session reset — it's a discipline tool, not a suggestion you can click past.
Yes — the Personal Execution Quality Scorecard (NBBO) applies the same methodology brokers use in their own aggregate execution-quality disclosures, but to your individual fills. Enter your fill and the market's NBBO at that moment, and it grades that specific trade A through F.
Yes. The FXCM-Specific Margin & Instrument Calculator uses FXCM's actual published contract specs rather than a generic formula, and the Swap/Rollover tool surfaces FXCM's real swap rates plus a triple-swap Wednesday alert — both built around FXCM's real published data, not industry averages.
This 4-extension category is a business tool for forex/CFD brokerage compliance and partnerships teams — not for individual traders. It covers marketing creative review, affiliate/IB content monitoring, multi-jurisdiction regulatory tracking, and dual-entity routing checks.
It checks a landing page, ad, or social post against a specific jurisdiction's rules before it goes live — correct prescribed risk-warning wording, your firm's own current loss percentage rather than a stale figure, and required formatting, flagging language that implies guaranteed profits.
In most jurisdictions, yes — and the IB/Affiliate Creative Compliance Monitor exists specifically for that exposure. It scans partner-run content for missing risk warnings, banned bonus offers, or leverage claims not permitted in that audience's jurisdiction.
This suite serves brokerage businesses protecting real regulatory and revenue exposure, priced at $99+/mo as a business compliance tool rather than a personal-use utility — still a fraction of what a dedicated compliance agency typically charges.
6 extensions built for the back-office side of wholesale FBA selling: suspension appeal document assembly, invoice-to-ASIN authenticity tracking, distributor account terms, brand authorization status, and 2026 FBA labeling compliance.
When Amazon flags a listing as inauthentic, it pulls the matching distributor invoice and your written explanation into the exact format Amazon's Plan of Action reviewers expect — turning a frantic email search into a same-day submission.
Yes — the Distributor Account Terms Tracker keeps net-30/60 terms, minimum order quantities, and rebate thresholds for every distributor account in one place instead of scattered spreadsheets.
No — every tool works from invoices and data you provide directly. Nothing in this toolkit connects to your live Seller Central session, keeping your account credentials entirely in your control.
12 extensions for brand owners and manufacturers: unauthorized-reseller monitoring, MAP compliance scorecards, counterfeit evidence organizing, gray-market source tracing, and tools for finding new qualified wholesale partners.
The Authorized Reseller Cross-Reference Watcher checks current sellers on your ASINs against the authorized list you maintain, flagging anyone selling your product who isn't on it — a lightweight version of what enterprise brand-protection agencies charge $2,000+/month for.
Yes — the Counterfeit/Gray-Market Evidence Organizer bundles timestamped screenshots, seller info, and test-buy photos into a case file formatted for Amazon Brand Registry or Project Zero submission. It doesn't file the report for you — you still submit it through Amazon's own channels.
By you. Every tool in this suite cross-references against the authorized-reseller list you maintain yourself — accuracy depends entirely on keeping that list current, since there's no external authority determining authorization status.
7 extensions for import/export businesses: sanctions screening, Letter of Credit discrepancy checking, an Incoterms explainer, multi-supplier landed-cost comparison, certificate requirement checks, and ISF deadline tracking.
No — it's a screening aid using the free public Consolidated Screening List. A match is a starting point for real due diligence, not a legal compliance guarantee, given OFAC's strict-liability standard on sanctions violations.
Yes — the Multi-Supplier Landed-Cost Normalizer accounts for different Incoterms across competing quotes, since a lower unit price under EXW can end up more expensive than a higher DDP price once freight and duty are included.
US ocean imports require a 10+2 Importer Security Filing before the vessel departs the foreign port — a frequently missed deadline for smaller, less frequent importers specifically. This tracker keeps that date visible against your actual shipment schedule.
6 extensions: scope-creep tracking for freelance disputes, vendor contract cancellation-window scanning, merchant processing fee auditing, 1099 threshold tracking, chargeback evidence bundling, and local SEO citation consistency checking.
It watches for phrases like "just one small thing" in your project threads, timestamps them, and builds a dated log — so when a client claims a feature was always in scope, you have a specific, dated record instead of relying on memory.
Yes — paste your monthly statement's total volume, fees, and transaction count into the Merchant Processing Fee Reality-Checker and it calculates your true effective rate, flagging it against typical rates for your business type.
No — every tool works from numbers and documents you enter directly. None of these extensions require connecting to your bank, payment processor, or accounting platform.
Our second-largest category with 13 extensions: shrinkflation tracking, a fake-discount verdict score, coupon-stacking calculators, warranty tracking, a secondhand theft-registry checker, insurance renewal alerts, and DeFi tools.
Instead of leaving you to interpret a price chart, it gives a plain verdict — "this sale price is actually 8% higher than the 90-day average" or "genuine discount, lowest price in 6 months" — based on real historical pricing data.
Yes — the Secondhand Item Theft-Registry Checker cross-references a serial number against registries like BikeIndex and flags it if reported stolen, a basic check most buyers don't know exists.
It reads your position using your public wallet address only, which is safe to share — it never requires a private key or wallet-connection permission.
4 extensions deliberately built around gaps that generic cap-rate calculators don't cover: off-market seller-motivation signals, short-term rental regulation checks, real rent-vs-comps comparisons, and 1031 exchange deadline tracking.
It scans public records — permits, code violations, tax delinquency, probate filings — for distress signals on properties before they're ever listed, rather than analyzing already-listed properties everyone else is running cap-rate math on.
It's built around currently published local ordinances, but STR regulation is one of the fastest-changing areas of local law — always verify directly with the city before finalizing a purchase decision.
No — the 1031 Exchange Deadline Tracker keeps your 45-day identification and 180-day closing deadlines visible against your actual dates. Your Qualified Intermediary remains the party actually executing the exchange mechanics.
Our smallest, most focused category with 3 extensions: sponsorship rate benchmarking for creators, an FTC disclosure compliance checker, and a supplier reliability score aggregator for dropshippers.
It compares a brand's offer against typical CPM and engagement-rate benchmarks for your follower count and niche, giving you a concrete, defensible number to counter with instead of just a feeling that an offer seems low.
No — it's a pattern-matching check against commonly required disclosure practices and placement, not a substitute for legal counsel on your specific situation.
That category is already heavily served by established players like AutoDS, Zendrop, and Sell The Trend. This toolkit deliberately targets the adjacent, less-covered problem of supplier reliability instead of competing head-on in a saturated space.

HOW EVERY EXTENSION IS BUILT
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.
Every calculation is documented in a full guide showing the exact formula and worked example — nothing runs as an unexplained black box.
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.
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.
Get weekly picks, new releases, and updates straight to your inbox. No spam, ever.
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.

Discover single-purpose browser extensions across problem-focused extensions — trading, Amazon selling, international trade, small business, consumer finance, real estate, and more. New tools are added regularly, and every extension is built and tested by me personally before it ships.
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:
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.
