Who wrote this?
We sell no gateway, proxy or model, and we are paid by nobody to rank. Several of the best-known comparisons are written by gateway vendors, so each number here is tagged with who wrote it.
The three tags
- OFFICIAL The vendor's own pricing page or docs, read by us on the date shown.
- VENDOR-WRITTEN An article by a different vendor that sells a competing or related product. We cite it, never alone when a vendor page exists, and we say so.
- OUR CHECK Our own fetch or arithmetic, for example "the price text appeared on the page" or a calculator result.
Rules
- Each price has a source URL and the date we read it. An entry older than 60 days is greyed.
- If sources disagree, we show both and do not pick (see Changes).
- We read a site's robots.txt before fetching a page. 0 vendor pages were blocked; for them we rely on a vendor-written article and say so.
- Paid notices (not open yet) never change a number. See Advertise.
