Flux

A modern, fluid currency converter that seamlessly localizes prices on any webpage with real-time global exchange rates.

Flux is a modern browser extension that seamlessly converts and localizes prices on any webpage using real-time global exchange rates. With a clean, minimal interface, Flux provides instant feedback and automatic price conversions directly on the sites you browse. Features: Real-Time Auto-Conversion: Automatically parses text and structured prices on the page, replacing them with your target currency. Modern UI: A fully responsive popup interface using the Space Grotesk font with a built-in Dark/Light mode toggle. Smart Caching Engine: API rates are cached locally in the browser to ensure instantaneous target currency swaps without redundant network calls. Performance Optimized: Uses debounced MutationObservers and pre-compiled regex logic to keep scrolling buttery smooth, even on infinite-scroll pages. Site-Specific Controls: Disable Flux on a per-site basis directly from the popup using the power icon, or toggle it globally. What's New in v2.3.1: 🐛 Bug Fix: Magnitude Word Support in Currency Conversion Previously, text like $4 million would only convert $4 — completely ignoring the "million" part. This resulted in wildly incorrect conversions (e.g., $4 → ₹336 instead of the correct ₹33,60,00,000). Now, Flux correctly recognizes and converts magnitude words across all 10 supported currencies. ✨ What's New Full magnitude word support — million, billion, trillion, thousand, hundred, and Indian magnitudes (lakh, crore) are now properly handled Abbreviation support — Shorthand like $5m, $3bn, £10k, ₹5cr are correctly converted Case-insensitive matching — $4 million, $4 Million, and $4 MILLION all work All 10 currencies patched — USD, EUR, GBP, INR, JPY, CAD, AUD, CHF, CNY, SGD Compact Format toggle — New "Coming Soon" setting in the popup for a future compact display mode (e.g., ₹33.6 crore instead of ₹33,60,00,000)
