The short version
- Only Ably has a free tier, so it costs nothing to try first.
- Each has a real cost: Ably standard and Pro plans layer usage-based charges for messages, connection minutes, and data transfer on top of the base subscription, adding cost complexity.; Enfuce coverage is European, so a programme that also needs US or Asian issuing requires a separate processor and a separate integration.
- They diverge on capability: Ably covers Pub/sub messaging, Enfuce covers Licensed issuing.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Ably
- Standard and Pro plans layer usage-based charges for messages, connection minutes, and data transfer on top of the base subscription, adding cost complexity.
- The jump from Standard ($29/month) to Pro ($399/month) is steep for teams needing more than 10k connections but not full Pro capacity.
- 24/7 mission-critical support and 99.999% uptime SLAs are reserved for the custom-priced Enterprise tier.
Enfuce
- Coverage is European, so a programme that also needs US or Asian issuing requires a separate processor and a separate integration.
- Where Enfuce acts as the licensed issuer it takes on regulatory risk and prices accordingly, so the convenience of skipping a sponsor bank is not free.
- European interchange caps limit programme revenue far below US levels, so business cases imported from a US card model do not survive the move.
- It is a smaller supplier than Marqeta or i2c, which means less negotiating room on scheme fees and a thinner partner ecosystem around it.
- Pricing is entirely quoted with monthly minimums, so low-volume programmes carry a fixed cost that does not scale down with a slow launch.
