A Sepolia faucet is a website or API that sends free test ETH to your wallet on Ethereum's Sepolia testnet, so you can pay gas while deploying and testing contracts. As of October 2026, the largest single drip on this list is the Chainlink faucet at 0.5 Sepolia ETH, per the Chainlink faucet page, while the Alchemy faucet sends 0.1 ETH every 24 hours to wallets that meet its mainnet requirements, per the Alchemy Sepolia faucet.
​

Sepolia is the testnet ethereum.org recommends as the default for application development, per the ethereum.org networks page. Every faucet below was opened on October 13, 2026, and every amount, cooldown and requirement comes from the faucet's own page on that date. Faucet terms change often, so treat the numbers as a snapshot and check the live page before you rely on one.
​

Each faucet here dispenses Sepolia ETH directly, publishes its drip size or cooldown on its own page, and is either listed by ethereum.org or the Sepolia client repository or run by a major infrastructure provider. Faucets that redirected away from a faucet page or showed no terms when opened were left out.
​

The ethereum.org networks page lists ten Sepolia faucets, and the eth-clients/sepolia repository keeps its own list. This article ranks the six that published usable terms when fetched. The Infura faucet link resolved to the Infura homepage rather than a faucet form on October 13, 2026, so it is not ranked. The ranking favors faucets a new developer can actually use: no mainnet balance, no paid account, and a cooldown short enough for a working day.
​

The Chainlink faucet publishes the largest single drip of the faucets checked, followed by Alchemy. Google Cloud sends a smaller amount with fewer hoops for most users, and QuickNode lets brand new wallets claim. The table compares drip size, cooldown and eligibility as each faucet states them.

Most Sepolia faucets gate claims to stop bots from draining them. The common checks are a minimum ETH balance on mainnet, a history of mainnet transactions, a signed-in account, a captcha or a cooldown per address. The right faucet depends on which of those checks your wallet can pass today.
​

The Chainlink faucet lists two Sepolia ETH drips of 0.5 ETH and a separate 25 LINK drip for testing Chainlink services. You connect a wallet before claiming. The page listed no cooldown when it was fetched, so expect a per-address limit and check the page if a claim fails.
​

The Alchemy faucet sends 0.1 ETH once every 24 hours and does not need an Alchemy account. The catch sits in its eligibility rules: the wallet needs at least 0.001 ETH on Ethereum mainnet, enough real mainnet transactions, and a low enough existing testnet balance. A fresh wallet with no mainnet history will not qualify.
​

The Google Cloud faucet sends 0.05 Sepolia ETH to an address or ENS name. Its FAQ says drips are rate limited per Google Account and per address, and that some requests are asked to prove a 0.001 ETH mainnet balance when the abuse system flags them. Google says not every request gets that check.
​

The QuickNode faucet is the friendliest option for a brand new wallet. Its FAQ says the base drip needs no QuickNode account, no post on X and no minimum mainnet balance, with one claim every 12 hours per network. Posting on X doubles the drip, and paid QuickNode customers can reach up to four times the base amount.
​

The Sepolia PoW Faucet run by pk910 trades CPU time for test ETH. You enter an address, let the browser mine, then stop and claim what you collected. It needs no account or mainnet balance, which makes it a fallback when every gated faucet refuses your wallet. The Sepolia client repository lists it as PoW powered.
​

The CDP Faucets docs list 0.0001 ETH per claim on Ethereum Sepolia and Base Sepolia, with up to 1,000 claims per 24 hours. Claims run through the CDP Portal or the CDP SDK and need a CDP account, per the CDP quickstart. The small drip suits scripted test setups more than a one-off deploy.
​

Pick by what your wallet can prove. A wallet with mainnet ETH and history can use any faucet here. A brand new wallet should start with QuickNode or the proof-of-work faucet. A team that funds many test accounts from code should look at the CDP Faucet API.

Sepolia uses chain ID 11155111 per the eth-clients/sepolia repository; RPC endpoints and explorers are covered in Sepolia testnet network settings.
​

Hoodi is the Ethereum testnet for validators and stakers, while Sepolia is for applications. Holesky is deprecated. Developers testing contracts should stay on Sepolia. Validator and staking work belongs on Hoodi, which has its own faucets and its own chain ID.
​

The ethereum.org networks page says Holesky has been deprecated since September 2025 and points staking operators to Hoodi. The Hoodi repository lists chain ID 560048 and a launch on March 17, 2025. The Google Cloud Hoodi faucet sends 1 Hoodi ETH per drip as of October 2026, and ethereum.org also lists a Hoodi PoW faucet run by pk910. QuickNode's faucet offers a Hoodi network option too, per its network selector.
​

Faucets are rationed, change their rules without notice and can run dry. A request that worked last month can fail today because of a new balance check. Sepolia itself also has a published support window, so long-lived test environments should plan for it.

No. Google's faucet FAQ states that testnet tokens have no real-world value and cannot be used on Ethereum mainnet, per the Google Cloud faucet.
​

To filter out bots. Alchemy asks for 0.001 ETH on mainnet plus mainnet activity, per its faucet FAQ, and Google may run the same balance check, per Google Cloud.
​

Yes. QuickNode's base drip needs no mainnet balance, per its faucet FAQ, and the Sepolia PoW Faucet pays for mining work instead.
​

It depends on network congestion, per the Google Cloud FAQ. Track the transaction on Sepolia Etherscan.
​

Sepolia. Ethereum.org describes Hoodi as the network for validator and staking tests, per its networks page.
