Bitcoin Core
free · open sourceBitcoin Core is the reference full-node software for Bitcoin. It downloads and independently verifies the entire blockchain on your own hardware, so you never have to ask an exchange or block explorer what the ledger says — you check it yourself. It needs several hundred gigabytes of disk and patience for the initial sync, but every other rung builds on it.

Mempool.space
Mempool.space is an open-source Bitcoin block explorer and fee estimator. The hosted site is the easy way to check a transaction; self-hosting it against your own node means you can verify any payment without trusting a third-party website or API. For a business accepting Bitcoin, a self-hosted instance turns "did the payment confirm?" into a question you answer yourself.
StartOS
StartOS, from Start9, is an open-source operating system for running your own server: a Bitcoin node, Lightning, password managers, and other personal infrastructure, installed and updated from a simple app-store interface. Compared to renting cloud services, your data and your node live on hardware in your house. You provide the machine and accept light maintenance duties in exchange.
Umbrel
Umbrel is a friendly operating system for a home server that runs a Bitcoin node, a Lightning node, and dozens of other self-hosted apps from an app-store interface. It turns "I should run a node" into an afternoon project on a Raspberry Pi or spare machine. The polish costs some transparency: parts of the project are source-available rather than fully open.
