Where each one falls short

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

Apidog

  • Free plan is capped at 4 users, limiting larger teams from using it at no cost.
  • Faster scheduled imports and unlimited projects require the Professional tier or higher.
  • Smaller community and plugin ecosystem compared to long-established tools like Postman.
  • Advanced enterprise security controls require the top-tier Enterprise plan.

Trustly

  • It is majority-owned by Nordic Capital, a private equity firm, so its long-term roadmap is ultimately oriented toward an eventual sale or IPO rather than indefinite independent operation.
  • Consumer familiarity with paying by bank transfer still lags card payments in most markets, so merchants typically see it used as a secondary option rather than a full card replacement.
  • The 1.15 to 3.15% merchant fee range is not a single published rate, so a merchant cannot know its actual cost without a sales negotiation.
  • As with all open banking-dependent payment methods, reliability depends on the consistency of the underlying banks' own APIs, which Trustly does not control.
  • Its verified payout functionality is heavily used in gaming and gambling, a sector with additional regulatory scrutiny, which is worth factoring in when evaluating vendor risk exposure by association.
