How we sorted: the lowest monthly price printed on each vendor's pricing page, cheapest first; products that only publish usage, yearly or quote pricing come last. Prices are copied from each vendor's public pricing page on the date shown; plan names and billing notes (per seat, billed yearly) are kept as the vendor writes them. "not published" or "Contact sales" means the vendor doesn't publish a price; we don't guess. Prices change; confirm with the vendor.
