This gist lists known "chain indexers" and related tools and technologies, eg. software components that are able to "follow the chain" and possibly index current or historical data.

• Oura (less of an indexer and more a building block) (Rust) https://github.com/txpipe/oura
• Scrolls (Rust) https://github.com/txpipe/scrolls
• Ogmios (also not really an indexer and more a node-interface) (Haskell, REST) https://ogmios.dev/
• Carp (builds on Oura, TS, Postgres) https://github.com/dcSpark/carp
• Marconi (Haskell) https://github.com/input-output-hk/marconi
• DB-Sync (Haskell, Postgres) https://github.com/input-output-hk/cardano-db-sync
• Kupo (Haskell, sqlite) https://cardanosolutions.github.io/kupo/#section/Overview
• marlowe-chain-sync (Haskell) https://github.com/input-output-hk/marlowe-cardano/tree/main/marlowe-chain-sync A specialised indexer for use with Marlowe runtime

• https://github.com/woofpool/cardano-private-testnet-setup (Shell) Scripts to run a private network
• https://github.com/input-output-hk/mithril/mithril-test-lab (Rust) wrapper to run cardano-node and interact with it through cardano-cli. In Rust because that's the implementation language of Mithril and easier to maintain for the team (there used to be a version in Haskell)
• https://github.com/input-output-hk/hydra/hydra-cluster (Haskell) wrapper to run cardano-node (and hydra-node). Interaction is done in Haskell using the cardano-api, provides few configurability but has a faucet that can be used to distribute funds
• https://github.com/input-output-hk/cardano-node/tree/master/cardano-testnet. (Haskell) Newer framework to spin-up nodes from Haskell code, to use in CI or ETE testing
• https://github.com/input-output-hk/cardano-node/tree/master/scripts/byron-to-alonzo (Shell) Scripts to spin up a cluster of machines and possibly evolve them through all the Eras
