How we research

WebFetch/WebSearch plain fetch of official pages, no browser. Values not on an official page are 'unknown'; third-party figures are labeled in notes only.

• Source first. Every platform page lists the exact URLs we read and the date we read them.
• Monthly USD where possible. When a vendor shows only annual-equivalent prices, or shows prices in another currency, we say so in the Billing column or the data notes.
• No invented numbers. If a price or limit wasn't published, or didn't load on the official page, it shows as Unknown.
• Third-party figures, such as review-site prices, appear only in the data notes and are labeled as third-party.
• Regular re-checks. We re-read pricing pages regularly and update the "checked" date.
