🌐 About ExtensionHub
Single-purpose Chrome extensions, built in-house, organized by the problem they solve.
📋 What Is ExtensionHub?
ExtensionHub is a single-developer library of Chrome extensions, built entirely in-house — not sourced or aggregated from other developers. Tools are organized into 9 problem-focused categories, making it easy to find the right one for the specific issue you actually have — whether that's auditing a trade fill, appealing an Amazon suspension, tracking an import deadline, or checking if a "sale" price is real.
The philosophy behind every tool is the same: solve one problem well instead of bundling unrelated features into a bloated all-in-one app you'll only half use.
🎯 Our Mission
To build narrow, transparent Chrome extensions that solve one real problem each — saving you time and giving you calculations you can actually verify.
We're committed to:
- Researching — Finding real, specific problems that existing tools don't solve well
- Building — Designing and developing every extension in-house
- Documenting — Publishing a full guide for every tool showing the exact formula and a worked example
- Testing — Personally verifying each extension before it ships
- Maintaining — Updating tools as regulations, formulas, and platforms change
📂 The 9 Categories
🛡️ How Every Extension Is Built
Every extension on ExtensionHub follows the same process before it ships:
- ✅ Problem Research — Confirming a real, specific gap exists before writing any code
- ✅ Transparent Formulas — Using public, documented methodology — SEC execution-quality rules, FXCM's own contract specs, IRS thresholds — never a black box
- ✅ Personal Testing — Verified by the developer before release
- ✅ Full Documentation — A guide explaining exactly how the tool works, with a worked example
- ✅ Ongoing Maintenance — Updated as rules, platforms, and regulations change
