  • They diverge on capability: 10x Banking covers SuperCore ledger, Thunder Client covers REST Client.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

10x Banking

  • Engagements are multi-year core replacement programmes with costs dominated by migration and integration, so the licence is a minority of what you actually spend.
  • The customer list is small and concentrated in large institutions, which makes reference checking and benchmarking difficult before committing.
  • It is a smaller vendor than Temenos or Finastra carrying a systemically important workload, and bank procurement teams treat that concentration as a genuine risk.
  • Product configuration replaces code but shifts complexity into configuration governance, which banks must staff and control just as carefully as software releases.
  • Value only appears after migration, so a programme cancelled or paused mid-transition leaves the bank running two cores and paying for both.

Thunder Client

  • Paid plans are billed annually only: Starter is $3 per user per month and capped at a maximum of 10 seats, Business is $7 per user per month with 500 monthly collection runs per user, and Enterprise is $16 per user per month for unlimited runs
