  • Blockfrost, an instant and scalable Cardano API for free

  • Carp, a modular indexer for Cardano with an SQL Postgres backend

  • Kupo, a  fast, lightweight and configurable chain-index for the Cardano blockchain

  • Marconi, the Cardano blockchain indexer for dApp developers

  • Ogmios, a lightweight bridge interface for cardano-node

  • Oura, the tail of Cardano

  • Scrolls, a read-optimized cache of Cardano on-chain entities.
