SubQuery review
An open-source toolkit for defining and running multichain indexers with GraphQL query endpoints.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SubQuery gives decentralized-application developers tools to define blockchain data sources, index them, and expose results through GraphQL. Teams describe projects with a manifest, GraphQL schema and mapping functions, then run them locally, on personal infrastructure or through the SubQuery Network and partner hosts. Its open-source tooling and free plan make it relevant to teams evaluating an indexer before committing to a deployment model. It is aimed at developers who need indexed data from one or more chains, rather than teams looking for a broad set of application-building services.
The central strength is the indexing workflow. TypeScript types can be generated from GraphQL schemas and contract ABIs, while importing EVM ABIs can generate data sources and handler functions. A project can index multiple chains into one shared database and query endpoint, and the documented supported-networks coverage is 304 across different network families. For applications that need to query EVM data nodes directly, JSON-RPC endpoints include additional block-filtering methods. These features suit teams with a clear data model and the engineering capacity to define and maintain project mappings.
Deployment choice is a practical differentiator: projects can run on a developer's machine, personal infrastructure, or the SubQuery Network, and consumers can access indexed deployments through decentralized Flex plans. The published pricing approach for Flex is pay-as-you-go, with Node Operators setting prices per project deployment; this is not a fixed subscription schedule. That flexibility may fit teams that want to compare operator offerings, but makes cost planning less straightforward than a standard tiered price list. Community support and documentation are the stated support channels. Choose SubQuery when custom multichain indexing and deployment control matter; teams seeking managed, fixed-price simplicity or broader developer-platform capabilities should consider alternatives.
SubQuery pros and cons
- Where it wins
- Combines multiple chains in a shared database and query endpoint
- Generates TypeScript types and EVM handlers from schemas and ABIs
- Supports local, self-hosted and SubQuery Network deployments
- Where it doesn't
- Project setup requires manifests, schemas and mapping functions
- Flex deployment pricing is set by Node Operators per project
- Its focus is indexing and querying, not a general blockchain development suite
