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
Turso
Pros
- + True per-tenant database isolation at SQLite pricing — 100 databases free, unlimited from $5.99/mo
- + Published pricing, overage rates, and even per-tier commit latency — rare transparency
- + Edge replication across 30+ locations with placement you control per database
- + Eleven-nines durability via S3-backed commits; MIT-licensed engine you can self-host
- + SQLite file-format and SQL compatibility keeps local dev and production aligned
Cons
- - No public uptime SLA on self-serve plans — the guarantee is durability, not availability
- - Rows-read metering punishes unindexed queries; costs can surprise the careless
- - EU databases still back up to S3 us-east-2 unless you bring your own buckets (Pro+)
- - SQLite dialect limits rule out query-heavy relational workloads
- - Big price jump from Scaler ($29/mo) to Pro ($499/mo) for priority support and compliance
