| Best for | Applications where the database must survive region loss without losing transactions — payments, ledgers, identity, multi-region SaaS, global gaming backends — and teams ready for distributed-SQL trade-offs | TypeScript teams building real-time, collaborative or AI-agent applications who want to replace an assembled backend stack with one reactive platform and value developer velocity over infrastructure control. |

CockroachDB
Pros
- + True multi-region survivability with serializable transactions and Postgres wire compatibility
- + Generous free tier: Basic at $0/month with 50M RUs and 10 GiB free monthly, $400 trial credits, no card required
- + Contractual SLAs: 99.99% availability, up to 99.999% multi-region on Advanced; P1 response targets published
- + Transparent per-component cost documentation and a public pricing calculator
- + Enterprise compliance path (CMEK, PCI DSS, HIPAA) and AWS/GCP/Azure coverage
Cons
- - Production costs climb fast: storage billed at 4.5x durability multiplier, plus backups, CDC and egress
- - September 2026 plan restructure (Cockroach Continuum) splits new and existing customers onto different rate cards
- - Distributed-SQL learning curve: RU model, planner differences from vanilla Postgres, cross-region latency
- - Overkill for single-region applications — managed Postgres is far cheaper for the same job
- - Proprietary managed plane; open-core self-hosting shifts the operational burden back to you
Convex
Pros
- + Replaces a whole backend stack — database, functions, sync, search, storage and auth — with end-to-end TypeScript type safety and ACID transactions
- + Generous economics for reactive apps: query/mutation compute free on serverless, plus a real free plan and pay-as-you-go Starter tier
- + All unit rates and per-tier limits published, including an honest 1.3x regional multiplier for EU and Canada
- + Core backend open-sourced (March 2024) with self-hosting option — genuine lock-in relief uncommon in this category
- + Well-funded ($110.5M through a $57M Series B in 2026), SOC 2 Type II, HIPAA compliant, with named production customers at real scale
Cons
- - Document model is not SQL — poor fit for Postgres estates, analyst workflows and BI tooling
- - Usage-based metering can surprise chatty clients; no hard spend caps on paid tiers
- - Support SLAs are a paid feature: 30-minute P1 response only in $1,000–$2,000/month premier tiers
- - TypeScript-first to the point of exclusion — a non-starter for non-TS teams
- - Self-hosting the open-source backend is an operational project most teams will only use as an escape hatch
