RxDB
Pros
- + Apache 2.0 core at $0 with replication, reactive queries and schema migration included
- + Pluggable storage engines keep one codebase across browser, Node, Electron and React Native
- + Mature project with a public changelog, 15,000+ commits and a documented replication protocol
- + Explicit conflict handling with revisions instead of silent last-write-wins
- + Tier pricing is published openly, including the exact free-tier limits
Cons
- - Paid tiers jump straight to $99/month billed annually with nothing in between
- - Free tier caps at 13 open collections; trial SQLite storage is evaluation-only at 500 documents
- - RxJS-shaped API carries a learning curve for teams new to observables
- - Effectively a one-primary-maintainer project with no support org behind the free tier
- - Sync backend is bring-your-own; there is no managed hosting or SLA on standard tiers
Appwrite Cloud
Pros
- + BSD 3-Clause open source with full self-hosting on any Docker host
- + Generous Pro resources: 2 TB bandwidth, 150 GB storage, 200K MAU at $25/month
- + Complete backend stack: auth, databases, storage, functions, realtime, messaging
- + Clear published overage rates and budget caps
- + Six regions across NA, EU, and APAC
Cons
- - No published uptime SLA on cloud plans
- - Free tier pauses projects after a week of inactivity; two-project limit
- - Per-project pricing multiplies cost for multi-project architectures
- - Smaller integration ecosystem than Firebase or Supabase
