Web3Gas price. One click away.
Browser extension that shows the current Ethereum gas price in gwei — with slow, standard, fast, and rapid tiers at a glance.
About
Always know what you're about to pay
Submitting an Ethereum transaction without checking the gas price is a gamble. ETH Gas Price is a minimal Chrome extension that surfaces live gas prices in gwei directly from the browser toolbar — no tab switching, no block explorer needed.
Features
Four speed tiers — Displays slow, standard, fast, and rapid gas prices simultaneously so you can pick the right trade-off between cost and confirmation time.
Persistent preference — Your selected tier is saved to Chrome sync storage and restored across sessions and devices.
Minimal footprint — Pure HTML/CSS/JS extension, no heavy dependencies. Opens instantly from the toolbar.
Secure rendering — Display content is sanitized with DOMPurify before insertion into the DOM.
Stack
Built as a Chrome extension (Manifest V3) in vanilla JavaScript, CSS, and HTML. Gas data is fetched by a background service worker and passed to the popup. Preferences stored via the Chrome Storage Sync API.
