ord

Ord is the reference implementation for Bitcoin Ordinals, the protocol that lets you inscribe data directly onto individual satoshis. The package includes a CLI wallet, a block explorer, and indexing tools. Fully free, open source, and community-funded.

Running ord requires a fully synced Bitcoin Core node with transaction indexing enabled: 1TB+ disk and days of initial sync. The CLI manages inscriptions and wallet operations. It processes every block as they come in, so you are committing to ongoing maintenance, not a set-it-and-forget-it setup.

Bitcoin developers and anyone building on the Ordinals protocol need this. There is no real alternative because this is the reference implementation. If you are not specifically building on Bitcoin Ordinals, this is not relevant to you. Niche but exactly right for that niche.

The catch: the block explorer renders untrusted HTML and JavaScript from inscriptions. The team warns about this explicitly. Host it with access controls, not publicly open.
