Methodology

How these rankings are built.

No pay-for-placement. Rankings are driven by documentation quality, reputation data, operational clarity, and whether the vendor exposes a useful product-level path.

  1. 01 · Documentation

    DSIP listing quality, COA access, and test visibility.

  2. 02 · Reputation

    Trustpilot rating and review depth where available.

  3. 03 · Operations

    Shipping windows, order handling, and regional coverage.

  4. 04 · Confidence

    Exact product-page listings beat vague vendor-level routing.
