# Sources Overview

> Sources Overview → DuckBrain ingest (Reference)

**Status:** Reference

DuckBrain ingests through **two lanes**, both landing in the same bronze envelope:

* **Lane A — local crawlers (bulk + private).** The `*crawl` family archives each platform into local SQLite; DuckBrain attaches the archive read-only and maps it in. Crawlers install automatically from the `init` platform picker.
* **Lane B — SaaS connectors (incremental).** Pipedream/Composio behind one proxy-first interface, for sources with no local crawler (Gmail, Calendar). Backfills prefer provider-native exports (e.g. Google Takeout) over API crawls.
