Hardhat

PoWFaucet is a modular testnet faucet for EVM chains with anti-abuse methods including a mining puzzle, captcha, IP limits, and Gitcoin Passport, and it backs the Sepolia proof-of-work faucet. Teams running a testnet self-host it to hand out test ETH without giving it all to one address.

hardhat-deploy is a Hardhat plugin for replicable deployments with named accounts, proxies, and diamonds. Builders install it when deployments must be repeatable across networks and track upgradeable contracts.

eth-docker is a Dockerized stack for deploying and managing execution, consensus, and validator clients on mainnet. Node operators use it to run a full node setup from configuration files instead of hand-installed binaries.
