  • DataStax's Astra DB documentation directs Standard plan customers to IBM's watsonx.data pricing for exact consumption-based rates following the DataStax/IBM deal, rather than publishing them on DataStax's own site

IAR Embedded Workbench

  • No pricing information published on product page; prospective customers directed to free trial or sales contact only
  • Pricing model not specified; customers must request quote or try free trial to understand licensing costs
  • Embedded development tools typically require expensive licenses, but specific IAR costs unavailable online
