## What it is
SubQuery is an open-source, multi-chain data indexing framework for web3 that lets developers extract, transform, and query blockchain data via custom GraphQL APIs. It supports 165+ networks (Polkadot, Ethereum, Cosmos, Solana, NEAR, and more) and includes a decentralized hosting network plus an AI Apps framework for agentic blockchain data applications.

## Use cases
- index blockchain events and smart contract data into queryable APIs
- build a dApp that needs historical on-chain data from Polkadot or Ethereum
- migrate an existing subgraph from The Graph to SubQuery
- index data from multiple blockchains in a single project
- query NFT and DeFi token data across EVM-compatible networks
- build agentic AI apps that answer natural-language questions about blockchain data
- self-host a blockchain data indexer without running your own nodes

## When to choose
- you need fast, flexible indexing of on-chain data across one or many supported blockchains
- you want custom GraphQL APIs over blockchain data without operating full nodes
- you are migrating from The Graph and want a similar workflow with broader chain support
- you want decentralized, censorship-resistant hosting for your indexer

## When to avoid
- your data source is not a supported blockchain network
- you need a fully managed centralized indexing service with no SDK work
- your project requires indexing off-chain web data rather than on-chain data
