The short version

  • Only Thunder Client has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; Weavr products are packaged rather than open, so a flow Weavr does not support is not something you can build around, and you discover the limits after integrating.
  • They diverge on capability: Thunder Client covers REST Client, Weavr covers Plug-and-play products.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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

Weavr

  • Products are packaged rather than open, so a flow Weavr does not support is not something you can build around, and you discover the limits after integrating.
  • Programme economics depend on interchange, and SaaS vendors routinely overestimate how much card volume their customers will actually route through the embedded product.
  • It is a small company with limited headcount supporting a regulated dependency, which is a real concentration risk for a feature your customers rely on.
  • Monthly minimums on card programmes mean a slow-adopting customer base leaves you paying for volume you never reach.
  • European interchange caps hold programme revenue well below what US embedded finance case studies suggest, so imported business cases do not transfer.
