The short version

  • Each has a real cost: Appwrite smaller ecosystem compared to Firebase; fewer third-party integrations and extensions; TrueLayer variable recurring payments, the strongest reason to choose TrueLayer, is a UK construct, and European businesses expecting the same capability in their market will not get it on the same timetable.
  • They diverge on capability: Appwrite covers REST API, TrueLayer covers Pay by bank.
  • 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

TrueLayer

  • Variable recurring payments, the strongest reason to choose TrueLayer, is a UK construct, and European businesses expecting the same capability in their market will not get it on the same timetable.
  • Payment conversion varies substantially by bank, and a bank with a slow or broken authentication journey drags results down regardless of vendor, so aggregate coverage numbers say little about your actual mix.
  • Pay by bank has no chargeback mechanism, which merchants like until a customer disputes a purchase and finds no scheme protection, making it a poor fit for categories where buyers expect card style recourse.
  • Pricing is unpublished and varies by market and product, so multi-country merchants cannot model cost without a full sales engagement and often find rates differ significantly between countries.
  • Open banking authentication requires the customer to leave the checkout and authorise in their banking app, and that redirect remains the largest source of drop-off compared with a stored card.

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
TrueLayer: Is VRP available outside the UK?

No. Variable recurring payments are a UK capability. EU adoption is on a slower path, with UK commercial VRP expanding into ecommerce during 2026.

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
TrueLayer: What does TrueLayer cost?

Not published. Per-payment fees are quoted by volume, market and product, usually with a platform component and a minimum commitment.

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
TrueLayer: Are there chargebacks on pay by bank?

No. Bank transfers have no card scheme chargeback mechanism, which removes that cost but also removes buyer recourse, so it suits some categories and not others.

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
TrueLayer: Which countries are covered?

The UK plus a substantial set of European markets under PSD2, though bank-level coverage and conversion vary by country and should be checked for your specific mix.

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.
