Substreams
Parallel streaming, from genesis to head.
Describe the data you want and let an AI coding agent scaffold the Rust module against Substreams codegen — you review and ship. Substreams fans the job out across parallel workers, backfills years of history in minutes, then keeps streaming at the head of the chain.

$ brew install streamingfast/tap/substreams
Parallelism
Up to 300 workers on one job. Backfills that take days elsewhere finish in minutes.
Composable
Modules import other modules. Fork any package on substreams.dev instead of starting cold.
Sink anywhere
Postgres, ClickHouse, files, PubSub, webhooks — or let us host the Sink or Store for you with Hosted Sinks/Stores.
Agentic-ready
Describe what you need in plain language and a Skills package scaffolds the Substreams module for you — no Rust experience required.
