Your indexer - run your way

01

Run it yourself

SubQuery is open-source and designed to be easy to run, meaning you have the freedom to run it locally on your own computer (or a cloud provider of your choosing). There are two ways to run a project locally, using Docker or running the individual components using NodeJS services.

SubQuery's Decentralised Network

Welcome to the future of web3 infrastructure - performant, reliable, and decentralised
The SubQuery Network enables an open web3 data revolution by allowing you to completely decentralise your infrastructure stack. Indexers serve the any data you need in a trustless and verifiable way.

Partner Hosting Solutions

There are a number of external centralised hosting services that offer reliable hosting of production SubQuery data indexing projects. These services are managed by external partners and are designed to make it easy to deploy, manage, and scale your SubQuery projects.

How does the SubQuery indexer work?

SubQuery is designed to make building your own custom API for your web3 project as easy and painless as possible. It just takes three steps
01
Initialise
Run subql init to create a new project from hundreds of different example templates, or autogenerate code from your own EVM ABIs or Cosmos Protobufs.
02
Build
All you need to do is edit three files, your GraphQL schema definition, your project manifest, and finally the mappings for your ETL pipelines.
03
Query
Run yarn dev to spin up a Docker container with your project (or deploy to our Network) and start querying against your indexed data via GraphQL.
