  • No release lifecycle: nothing tracks what is installed or supports rollback the way Helm does
  • Patch syntax is fiddly for anything beyond simple field replacement

You.com

  • Pricing tiers beyond the pay-as-you-go table are not published and require contacting sales for volume discounts.
  • Finance Research API is priced significantly higher than the other endpoints, at $110 per 1,000 calls.
  • No self-serve dashboard details are published for managing enterprise zero-retention settings.
