Where each one falls short

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

Aiia

It is now part of Mastercard rather than an independent company, so a business specifically wanting to avoid card network dependency in its banking infrastructure no longer gets that separation by choosing Aiia.
Pricing is not published and requires engaging Mastercard's open finance sales process, which can be a heavier sales motion than dealing with a smaller independent open banking provider.
Its strongest bank coverage remains concentrated in the Nordics and Northern Europe, so companies needing dense coverage in Southern or Eastern Europe should verify current bank connectivity before committing.
Brand confusion is real: developer documentation, login portals and older case studies still reference "Aiia" while newer Mastercard material refers to "Mastercard Open Banking," and a company researching either name in isolation may miss half the relevant material.
As with any open banking platform, reliability still depends on the consistency of the underlying banks' own APIs, which is a systemic industry issue rather than something Aiia specifically controls.

Appwrite

Smaller ecosystem compared to Firebase; fewer third-party integrations and extensions
Analytics, crash reporting, and A/B testing not included (Firebase includes these)
Requires infrastructure management for self-hosted deployments; not fully managed like Firebase Cloud
Mobile app support not as mature as Firebase's native iOS/Android SDKs
