🚀 ExtensionHub.app
Instantly navigate the complete library of browser extensions, productivity tools, and expert guides. Find curated tools for privacy, security, and efficiency, plus in-depth reviews—all in one streamlined directory.
What Is ExtensionHub.app?
ExtensionHub.app is a single-developer library of single-purpose Chrome extensions. Every extension is built in-house by Muhiuddin Alam — not sourced or aggregated from other developers.
The 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.
- 🔧 22 extensions today — with new ones added regularly toward 100+
- 🔒 Local-first data — most extensions run entirely in your browser
- 💵 Free core, forever — every extension keeps its core features free after the 14-day trial

Why You Can Trust ExtensionHub
🔒 Trust built in Local-first, private by default, and built with transparency.
Every extension is designed, built, and tested by Muhiuddin Alam personally before it ships. Calculations are based on transparent, publicly documented methodology — SEC execution-quality rules, OFAC's public screening list, IRS thresholds — never a black box. Most extensions run entirely in your browser; the only routine network call most tools make is an optional Pro license check via Gumroad.

Data Privacy, Performance & Permissions
- 🔒 Local‑only storage: All data (settings, history, logs, cases) is stored exclusively in your browser using
chrome.storage.local. - 🔌 Minimal network calls: Most extensions make no external network calls. The only routine call is an optional Pro license check via Gumroad.
- 🛡️ Minimal permissions: Each extension requests only the permissions it actually needs — never broad internet access unless required for its core function.
- 📋 No telemetry: No analytics, no tracking, no data collection. What happens in your browser stays in your browser.
Common Mistakes to Avoid
Fix: Each extension is a separate Chrome extension. Install only the ones you need — they work independently.
Fix: Each extension is built for a specific use case. Read the extension's guide to understand exactly what it does.
Fix: Pro is per extension. One subscription unlocks all features in that specific extension only.
A Note on Accuracy
Transparent calculations: Every formula is based on publicly documented sources — SEC execution-quality rules, OFAC's public screening list, IRS thresholds, and other government/regulatory data. No black-box algorithms.
Tested logic: Each extension's core logic is tested before release. Where real-world APIs are used (e.g., GitHub's REST API, Gumroad's license API), the extension handles rate limits and errors gracefully.
Honest limitations: Every extension guide includes a "Note on Accuracy" section documenting specific limitations — what the tool can and cannot do.
