How it works

  1. 01

    Pick the vendors your company uses.

    Browse the catalog of 104 — Stripe, OpenAI, AWS, Atlassian, Notion, and the rest of the usual stack.

  2. 02

    We monitor every page for changes.

    Each vendor publishes differently — HTML lists, PDFs, embedded tables, separate AWS-region lists. We normalize them so a change is a change.

  3. 03

    You get an email with a clear before/after.

FAQ

Where does this data come from?
Each vendor's official subprocessor page. We link the source and timestamp every check.
Is this really free?
Yes. It stays free for DPOs and vendor-risk teams. A separate paid product for vendors funds this side.
How fast will I find out about a change?
Within a week. Every vendor's page is re-captured on a weekly cycle, and a change is flagged as soon as the list differs from the previous capture.
My vendor isn't in the catalog. Can you add it?
Email hello@subdrift.co. We prioritize by how many people ask.
Are you affiliated with any of these vendors?
No commercial relationship with anyone listed. We read their public pages, same as anyone.
