Where each one falls short

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

i2c

  • Developer experience lags API-native competitors, and teams expecting Stripe-grade documentation and sandboxes find an enterprise integration project instead.
  • Implementations lean on i2c or partner professional services, so timelines and costs are set by a services queue rather than by your own engineering speed.
  • Pricing is per active card and per transaction with monthly minimums, none of it published, so comparing bids requires modelling your own portfolio carefully.
  • Configuration flexibility means product behaviour lives in platform settings rather than in your repository, which complicates version control, testing and audit trails.
  • As a private company with a broad global footprint, regional support depth is uneven, and a programme in a smaller market may get thinner service than a flagship account.

Janus Gateway

  • No commercial pricing published; open-source project without official commercial offerings
  • Community-supported only; no vendor commercial support or SLA available

Answered from the vendors’ own pages

i2c: Does i2c issue the cards itself?

No. It processes; issuance sits with a bank or licensed issuer, and in most markets you need that relationship separately.

Janus Gateway: How much does Janus Gateway cost?

Janus Gateway has no pricing model; it is a free open-source WebRTC server developed by Meetecho. The general-purpose server is available for download at no cost. There are no subscription tiers or commercial licensing fees.

Source
i2c: Can it handle revolving credit?

Yes. Credit, instalments and buy-now-pay-later sit on the same platform as debit and prepaid, which is unusual among modern processors.

Janus Gateway: Is Janus Gateway supported commercially?

Janus Gateway is community-supported open-source software with no official commercial support or SLA from the vendors. While Meetecho developed the project, users must rely on community documentation and forums for assistance.

Source
i2c: Is it self-serve?

No. Expect a configuration-led implementation with professional services rather than signing up and calling an API.
