SQD (formerly Subsquid) review
A TypeScript-focused toolkit for indexing and streaming blockchain data into your own systems.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
For teams that need to move blockchain data into applications or analytics systems, SQD (formerly Subsquid) provides an indexing and data-pipeline toolkit rather than a contract-development environment. Its Portal API streams historical and real-time data, while the Squid and Pipes TypeScript SDKs help developers decode and transform records, then persist them to destinations such as PostgreSQL, ClickHouse, BigQuery, Parquet, or cloud storage. The category fit is strongest for custom cross-chain pipelines: the platform covers EVM, Solana, Bitcoin, Tron, Hyperliquid, and Substrate networks, and supports querying, indexing, and deployment.
SQD offers both managed and self-hosted routes. Indexers can be deployed through SQD Cloud, while the Squid SDK can be self-hosted. Generated GraphQL APIs from indexer schemas and handling for chain reorganizations and block rollbacks address practical pipeline needs. The range of destinations, including Kafka and Snowflake, gives teams options for connecting indexed data to existing storage and processing workflows. This breadth makes SQD more relevant to developers shaping their own data flows than to teams seeking a ready-made application or a platform centered on smart contracts.
The published monthly plans include Public at $0, with Portal access, no API key, and limited access across chains; Testing at $0, with an API key required; Starter at $99, for commercial production use with email support; and Growth at $499, with priority support and a 30-day free trial. Enterprise uses custom pricing, an annual contract, and dedicated infrastructure. The vendor says Portal billing is not live and paid plans are available through early access, with 14 days' notice before billing begins. Choose SQD if TypeScript-based indexing, deployment flexibility, and downstream data targets matter; look elsewhere if your primary need is contract development or a ready-to-use blockchain application.
