# Data Indexers (/docs/unichain/tools/data-indexers)

Query indexed onchain data for subgraphs, APIs, and analytics on Unichain.

## Allium
[Allium](https://www.allium.so/) is a real-time analytics platform that provides both historical and real-time data to institutions and crypto enterprises. Allium delivers data to customers any way they need it - interactive dashboards, a simple query interface, flexible APIs, or custom integrations like data shares & streams.

Allium developed the Uniswap v4 Analytics Dashboard and Unichain Analytics Dashboard with Uniswap Labs.

## GhostGraph
[GhostGraph](https://GhostGraph.xyz/) makes it easy to build blazingly fast indexers (subgraphs) for smart contracts.

GhostGraph is the first indexing solution that lets you write index transformations in **Solidity**. Unichain dApps can query data with GraphQL using hosted endpoints.

To get started, you can [sign up for an account](https://app.ghostlogs.xyz/ghostgraph/sign-up) and follow [this quickstart](https://docs.ghostlogs.xyz/category/-getting-started-1) guide on how to create, deploy, and query a GhostGraph.

## SQD
[SQD Network](https://docs.sqd.dev/subsquid-network/overview/) is a decentralized query engine optimized for batch extraction of large volumes of data.
It currently serves historical onchain data ingested from 100+ EVM chains, including Unichain Sepolia.

The indexing service provides EVM event logs, transaction receipts, traces, and per-transaction state diffs.

To get started, visit the [EVM API](https://docs.sqd.dev/subsquid-network/reference/evm-api/) or see the [Squid TypeScript SDK](https://docs.sqd.dev/sdk/quickstart/).

## SubQuery
[SubQuery](https://subquery.network/) is an open source, multi-chain blockchain data indexer that provides developers with fast, flexible APIs for Web3 projects. SubQuery supports 275+ ecosystems, including Unichain, and lets developers aggregate data across many blockchains in one project. Other advantages include high indexing performance with multiple RPC endpoint configurations, multi-worker capabilities, and a configurable caching architecture.

To get started building your custom API for your next Unichain project, visit the [Unichain quick start](https://academy.subquery.network/indexer/quickstart/quickstart_chains/unichain.html) documentation page.

## The Graph
[The Graph](https://thegraph.com/) makes it easy to organize and access onchain data.

The Graph is the original decentralized data marketplace that invented and standardized Subgraphs, which are open APIs you can query to rapidly serve data into your Unichain application's frontend. With The Graph, you can build serverless applications that run entirely on public infrastructure.

To get started, visit the [documentation](https://thegraph.com/docs/en/) or see [this quickstart](https://thegraph.com/docs/en/cookbook/quick-start/) on how to create, deploy, and query a subgraph that organizes Unichain data.
