Referral relationships
Some internal entry links redirect to a provider using an existing referral code. We may receive compensation from qualifying activity. Eligibility, tracking and benefits depend on the provider; we do not guarantee attribution, a discount or reward stacking.
How links are presented
Promoted Open buttons use configured internal shortlinks. Ordinary official-information links are references. When a suitable referral route has not been established, we withhold the promoted Open button while retaining factual coverage.
Listing order
The full directory is alphabetical. Featured tools are a starting selection rather than paid placements or an overall ranking. See our verification method.
