A lightweight protocol translation service acting as a translation interface between Cardano nodes and applications written in languages besides Haskell.
Ogmios is not for applications and DApps interacting with the Cardano blockchain at the highest level. It is the best for “low-level work” where one needs to access every bit of the protocol, or for those building wallets, explorers, and smart contract application backends. Anything available on-chain is available through Ogmios.
Ogmios takes up relatively little data, although its resource usage is strongly linked to the application using it. Ogmios is open sourced and there is a TypeScript client library and REPL for Ogmios, and the developer hopes to build it into a more capable SDK for Cardano in the future.
