## What it is
Graph Node is the core indexing component of The Graph protocol, written in Rust. It extracts and organizes data from blockchains such as Ethereum into subgraphs stored in PostgreSQL and serves that data over a GraphQL API.

## Use cases
- index ethereum smart contract events into queryable entities
- serve blockchain data over graphql for a dapp frontend
- run a local graph node to test subgraphs during development
- query defi or nft protocol data without running my own data server
- build an open api on top of on-chain data
- self-host blockchain data indexing infrastructure

## When to choose
- you need structured, queryable access to blockchain data via GraphQL
- you are developing or testing subgraphs locally
- you want to self-host indexing instead of relying on hosted services
- you need to index smart contract events across many EVM networks

## When to avoid
- your data is not blockchain-related
- you only need a simple REST API over a traditional database
- you cannot operate PostgreSQL, IPFS, and an Ethereum node
- you want a fully managed solution without infrastructure overhead

## Facets
- artifact type: service
