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; Unit your product depends on a sponsor bank you do not contract with directly, and 2024 showed what that means: Thread Bank received an FDIC enforcement action naming its banking as a service programmes and Blue Ridge Bank went under an OCC consent order and offboarded fintech partners.
  • They diverge on capability: Appwrite covers REST API, Unit covers Deposit accounts.
  • 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

Unit

  • Your product depends on a sponsor bank you do not contract with directly, and 2024 showed what that means: Thread Bank received an FDIC enforcement action naming its banking as a service programmes and Blue Ridge Bank went under an OCC consent order and offboarded fintech partners.
  • Programme approval by the bank is a separate gate from signing with Unit, and it can add months and impose product restrictions that were not visible during the commercial conversation.
  • Compliance obligations are shared but the operational load lands on you, and platforms consistently underestimate the staffing needed for disputes, escalations and the bank ongoing oversight requests.
  • Pricing is unpublished and blends platform fees, per-account and per-transaction charges and interchange sharing, which makes it hard to model unit economics before you have volume and easy to be surprised by the minimum.
  • Migrating a live deposit programme to a different provider or bank is extremely disruptive because it involves moving customer accounts and card credentials, so switching costs are far higher than for ordinary software.

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
Unit: Who actually holds the money?

A chartered partner bank, not Unit. Deposits sit at the sponsor bank and FDIC insurance flows from that bank, so its condition is your condition.

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
Unit: What happened with Unit sponsor banks in 2024?

Thread Bank received an FDIC enforcement action that explicitly named its banking as a service and lending as a service programmes, and Blue Ridge Bank was under an OCC consent order from January 2024 and offboarded fintech partners. Blue Ridge exited the order in late 2025.

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
Unit: What does Unit cost?

Not published. Expect a platform fee, per-account and per-transaction charges, an interchange share and a minimum commitment.

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
Unit: Do we need our own compliance team?

Yes. Unit supplies tooling and the bank sets the rules, but disputes, escalations and evidence for bank oversight require named people on your side.

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.
