Monitoring Ethereum gas fees has become an essential skill for anyone interacting with the blockchain—whether you're minting NFTs, swapping tokens, or simply transferring funds. High network congestion can cause gas prices to spike unexpectedly, turning a routine transaction into a costly one. For budget-conscious users, timing your interactions during low-fee periods can lead to significant savings.
In the past, Gas Now was the go-to tool for real-time gas tracking. However, it discontinued service after October 15, 2021, leaving many users searching for reliable alternatives. This guide compiles the most accurate and user-friendly gas fee monitoring tools available today—covering both web-based platforms and browser extensions.
Whether you're a DeFi enthusiast, NFT collector, or casual blockchain user, understanding how and when to track gas fees is crucial. Below, we break down the top options into two categories: web tools and browser extensions, with clear recommendations based on accuracy, usability, and real-time performance.
Best Websites to Track Ethereum Gas Fees
For users who prefer checking gas rates directly from their browser without installing additional software, these websites offer reliable data and intuitive interfaces.
1. mycointool.com/gasnow
A solid alternative to the original Gas Now, this platform provides real-time gas price estimates across different transaction speeds—slow, average, and fast. One standout feature is its custom alert system, which allows users to set thresholds and receive notifications when gas drops below a specified level.
This makes it especially useful for those waiting for optimal times to execute transactions. The interface is clean and mobile-responsive, though it lacks some advanced analytics found in other platforms.
👉 Discover real-time gas alerts and optimize your transaction timing.
2. app.defisaver.com
Primarily a DeFi automation platform, DefiSaver also includes a built-in gas price tracker. While functional, the layout can feel cluttered, and image scaling issues (as noted by some users) reduce visual clarity. It’s more suited for existing DefiSaver users managing automated positions than standalone gas monitoring.
Still, if you’re already using the platform for yield optimization or loan management, keeping an eye on gas fees here adds convenience.
3. ethgas.watch
ethgas.watch delivers clean, minimalistic data with clear distinctions between safe low, standard, and peak gas rates. A key advantage is its email alert functionality—users can subscribe to updates that notify them of major fluctuations.
This is ideal for passive monitoring without needing constant manual checks. The site sources data directly from Ethereum nodes, contributing to its reliability.
√√√ ❥ 4. etherscan.io/gastracker
Widely regarded as one of the most accurate gas tracking tools, Etherscan’s Gastracker leverages data from its vast network of Ethereum nodes. It displays current gas prices for slow, standard, and fast transactions, along with historical trends and percentile-based estimates.
Its integration with the broader Etherscan ecosystem means users can cross-verify transaction details, contract activity, and network health—all in one place. With high uptime and trusted data sources, this is our top-recommended website for serious Ethereum users.
5. ethgasstation.info
Once a leading gas estimator, EthGasStation has seen declining accuracy in recent years. Some users report discrepancies between displayed and actual execution costs. While still operational, it no longer matches the precision of newer tools.
Proceed with caution—this may be better suited for general trend observation rather than exact fee planning.
6. gasinfo.io
A lesser-known but surprisingly accurate platform, gasinfo.io offers real-time gas pricing with breakdowns by transaction type and network congestion levels. It also supports multi-chain data, making it useful for users active beyond Ethereum.
The design is straightforward and responsive, though the lack of alert systems limits its utility for hands-off monitoring.
Best Browser Extensions for Real-Time Gas Tracking
For frequent blockchain interactors, having gas data always visible—right in your browser toolbar—is a game-changer. These extensions work similarly to MetaMask’s built-in features but often provide deeper insights.
√√√ ❥ 1. Blocknative ETH Gas Estimator
Available on the Chrome Web Store, Blocknative offers near-instantaneous gas price updates with minimal lag. Its estimates closely mirror actual on-chain conditions, making it our top pick among extensions.
The popup interface shows suggested fees for different confirmation speeds and refreshes automatically during periods of volatility. It integrates seamlessly with wallets like MetaMask and is particularly helpful during NFT mints or flash sales when every second counts.
👉 Stay ahead of network congestion with live gas updates in your browser.
2. DeFi Saver Gas Prices Extension
While functional at times, this extension suffers from inconsistent data syncing. Users have reported mismatches between extension readings and actual network fees, leading to overpayment or delayed confirmations.
It’s best used as a secondary reference rather than a primary decision-making tool.
3. Ethereum Gas Price Extension
This basic extension displays current gas prices but often fails to update promptly during sudden spikes. When it does refresh, the numbers are generally accurate—but the delay defeats the purpose of real-time tracking.
Not recommended for time-sensitive operations.
4. Firefox Add-on: Ethereum Gas Price Extension
For Firefox users, there’s a compatible version available on Mozilla’s add-ons site. While untested by many due to Chrome’s dominance, it follows similar principles—displaying average gas costs in gwei.
If Chrome extensions disappoint you long-term, switching browsers might be worth exploring—especially since MetaMask works equally well on Firefox.
Frequently Asked Questions (FAQ)
Q: Why do Ethereum gas fees fluctuate so much?
A: Gas prices are driven by supply and demand. When many users interact with the network (e.g., during NFT drops or DeFi launches), competition for block space increases, pushing fees higher.
Q: Can I save money by waiting to transact?
A: Absolutely. Using tools like Etherscan’s Gastracker or mycointool’s alerts helps identify low-congestion periods—often saving 50% or more on fees.
Q: Are browser extensions safer than websites?
A: Both are generally safe if downloaded from official stores (Chrome Web Store, Firefox Add-ons). Always verify developer authenticity before installation.
Q: Do these tools support other blockchains?
A: Some do—like gasinfo.io, which covers BSC and Polygon. However, most focus primarily on Ethereum.
Q: Is there a completely free gas tracking tool?
A: Yes—all listed tools are free to use. None require subscriptions or payments for core features.
Q: How often should I check gas prices?
A: For non-urgent transactions, checking once or twice daily suffices. During high-activity events (e.g., token launches), continuous monitoring via extensions is advisable.
Choosing the right gas monitoring tool depends on your usage pattern. For accuracy and trustworthiness, Etherscan’s Gastracker and Blocknative’s extension stand out as the best-in-class solutions.
Whether you're minimizing costs or maximizing execution speed, leveraging these tools ensures smarter on-chain decisions. As Ethereum continues evolving—with upgrades aimed at lowering fees—staying informed remains your greatest advantage.
