Cardano Ogmios
Ogmios (opens in a new tab) is a lightweight bridge interface for Cardano-node. It offers a WebSocket API that enables local clients to speak Ouroboros' mini-protocols via JSON/RPC.
Demeter (opens in a new tab) provides a running instance of Ogmios available for your project.
Accessing your Ogmios instance
Inside the Ogmios extension, you can get all the required values for connecting to your instance.
The Ogmios instance provided will work with a Node running in the network where your project has been created ( preview / preprod / mainnet)

REPL
A Read-Eval-Print Loop, or REPL, is a computer environment where user inputs are read and evaluated, and then the results are returned to the user. REPLs provide an interactive environment to explore tools available in specific environments or programming languages. Demeter (opens in a new tab) provides a running environment accessible from the Web user interface so you can execute Ogmios (opens in a new tab) commands.
