Substreams Search

Search, inspect, and analyze Substreams packages from the substreams.dev registry — from discovery to sink deployment.

Tools

• inspect_package — Inspect a .spkg file to see its module graph (DAG), protobuf output types, dependencies, and a Mermaid diagram
• list_package_modules — Lightweight module listing with types and inputs/outputs
• get_sink_config — Analyze sink configuration, extract SQL schemas, and generate ready-to-run CLI commands
