Where each one falls short

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

Skaleet

  • The installed base is in the tens rather than the hundreds, so the pool of consultants and systems integrators who know the platform is small and expensive.
  • Speed references are mostly greenfield launches inside large groups, which is an easier problem than migrating an existing book off a legacy core.
  • It is European-centric, with payment rails and regulatory work concentrated on SEPA and EU requirements rather than global coverage.
  • As a smaller vendor carrying a bank core, it attracts hard concentration and viability questions in procurement that larger competitors do not face.
  • Pricing is unpublished and scaled by accounts and transactions, so a bank whose volumes grow faster than forecast faces cost escalation it did not model.

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
