The short version

  • Only Appwrite has a free tier, so it costs nothing to try first.
  • Each has a real cost: Appwrite smaller ecosystem compared to Firebase; fewer third-party integrations and extensions; Tink visa owns Tink, and pay-by-bank exists to move payments off card rails, so the roadmap and pricing of the product you are using to reduce interchange are set by the company that earns the interchange.
  • They diverge on capability: Appwrite covers REST API, Tink covers Account data access.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

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

Tink

  • Visa owns Tink, and pay-by-bank exists to move payments off card rails, so the roadmap and pricing of the product you are using to reduce interchange are set by the company that earns the interchange.
  • Coverage is Europe only, so a product serving both European and United States users runs a second aggregator with a different data model and a separate contract.
  • PSD2 connection quality varies sharply by bank, and headline connection counts hide wide differences in success rate, consent lifetime and re-authentication frequency that determine what users actually experience.
  • Consent under PSD2 expires and requires periodic re-authentication, so any product depending on continuous data access has a recurring user friction it cannot design away, and drop-off at re-consent is a real product problem.
  • Pricing is quoted with data access and payment initiation priced separately, and there is no published rate card, so small merchants cannot compare pay-by-bank economics against card acceptance without a sales process.

Answered from the vendors’ own pages

Appwrite: Can Appwrite be self-hosted?

Yes. Appwrite is fully open-source and self-hosted with a single Docker command. Self-hosting is completely free with no feature restrictions, unlike the managed Appwrite Cloud.

Source
Tink: Who owns Tink?

Visa, since 2022. That is directly relevant if you are adopting pay-by-bank specifically to reduce card costs.

Appwrite: What is Appwrite Cloud's pricing?

Appwrite Cloud offers a free tier with unlimited projects, 75K monthly active users, and 10GB storage with no time limit. Pro plan starts at $15/month per organization member. Scale plan at $599/month includes dedicated resources and SOC 2 compliance.

Source
Tink: Do I need my own PSD2 licence?

No. Tink holds AIS and PIS licences from the Swedish FSA passported across the EEA, and customers can operate as its agent rather than obtaining their own authorisation.

Appwrite: What programming languages does Appwrite support?

Appwrite provides SDKs for 15+ languages including JavaScript, Flutter, Swift, Kotlin, Python, Ruby, PHP, .NET, and more, offering more language flexibility than Firebase.

Source
Tink: Does Tink cover the United States?

No. It is a European platform. US coverage requires a separate provider.

Appwrite: What backend services does Appwrite provide?

Appwrite includes Auth (with multi-factor auth), Databases, Storage (with compression and encryption), Serverless Functions, Messaging, Realtime subscriptions, and Sites (for hosting static and full-stack apps).

Source
Tink: How reliable are the bank connections?

It varies by institution far more than the headline count of roughly 6,000 connections suggests. Ask for per market and per bank success rates and consent lifetimes for the banks your users actually hold accounts with.

Appwrite: Does Appwrite include real-time capabilities?

Yes. Appwrite's Realtime service covers all platform services by default through WebSocket subscriptions, enabling real-time updates across databases, functions, and messages.

Source
Appwrite: How does Appwrite compare to Firebase on costs?

Appwrite offers better cost predictability. Firebase's pay-per-read/write model can lead to unexpected bills with runaway queries, while Appwrite's self-hosted model only requires paying for your own infrastructure with completely predictable costs.
