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.

Stoplight

  • The free plan allows one project and one user
  • Private projects, multi branch support and custom domains start at the Startup plan, $113 a month billed annually
  • SSO and shared style guides are Pro Team only, at $362 a month billed annually
  • Seats beyond each plan's allowance are $11 to $27 each per month depending on tier and billing period

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.

Stoplight: How much does Stoplight cost?

Stoplight starts with a free plan (1 project, 1 user), then Basic at $56/month per user (or $44/year), Startup at $147/month per user (or $113/year), Pro Team at $453/month per user (or $362/year), and Enterprise at custom pricing.

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.

Stoplight: How many included users are in each Stoplight plan?

Basic includes 3 users, Startup includes 8 users, and Pro Team includes 15 users. Additional users beyond the included count cost $14/month for Basic and Startup, or $27/month for Pro Team.

Source
i2c: Is it self-serve?

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

Stoplight: Does Stoplight offer a free trial?

Yes, all paid Stoplight plans include a 14-day free trial. The free plan has no trial period as it is always available.

Source
Stoplight: Does Stoplight's free plan have limitations?

Yes, the free plan includes only 1 project and 1 user. Users viewing public documentation anonymously are not counted toward the 1-user limit.
