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.

The Kurtosis ethereum-package spins up reproducible multi-client Ethereum devnets, including mev-boost and supporting tooling. Builders run it when they need a local network that mirrors a real client mix.

DAppNode is an operating system with an app store for running Ethereum execution and consensus clients and other node software on your own hardware. Someone setting up a home node installs it and picks client packages instead of configuring each service by hand.
