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 v2.2: Redesigned Light Mode with a vibrant fintech aesthetic. Fixed race conditions for smoother currency switching. Improved regex matching for USD symbols. Added official support for Firefox and Edge.
