Deep dive: CockroachDB
When to choose CockroachDB
Choose CockroachDB if you operate a geographically distributed system serving multiple regions from a single database, require zero-downtime upgrades, or need true ACID guarantees across nodes. Best for teams with 5+ engineers and >$5k/month database budgets. The serverless tier is appealing for early-stage companies that want global replication without managing ops. Choose it WRONG if you're building a typical CRUD app (Postgres is cheaper, faster to market), have simple data that fits in one region, or lack distributed systems expertise on the team. CockroachDB's operational complexity is real—debugging distributed transactions, understanding replication latency, and managing cluster topology are non-trivial. Early-stage teams often find they've bought global resilience they don't yet need.
Real-world use case
A fintech startup serving 15 countries built a real-time payment settlement platform on CockroachDB. They chose it over 3 separate Postgres instances to avoid managing replication and cross-region consistency. Setup took 3 weeks (vs. 1 week for single Postgres); training ops team added another 2 weeks. Database cost: $800/month serverless tier (3TB throughput). Transaction volume: 2M/month across regions with <100ms p99 latency. The upside: a region failure didn't need a failover—queries just rerouted automatically. The downside: some complex window functions from legacy Postgres didn't port over, requiring query rewrites. They spent 40 hours on optimization after launch because the query planner made unexpected choices on distributed joins.
Hidden gotchas
CockroachDB's serverless billing is unpredictable—a traffic spike or slow query can consume RUs (request units) much faster than expected, causing surprise bills. The query optimizer makes non-obvious decisions on distributed queries; a query that's fast in single-region Postgres can become a cross-region nightmare. Some Postgres features don't work: recursive CTEs, certain window functions, and full-text search. Replication lag between regions means you can't read your own writes immediately across regions (eventual consistency edge case). Connection pooling is mandatory at scale, but configuration is error-prone. The free tier (5GB) is too small for real apps; jump to paid is steep. Backup restore is asynchronously processed and can take hours, not minutes. Batch imports are throttled aggressively to protect other tenants, making data migration slow.
Pricing breakdown
CockroachDB Serverless starts free with 10 GiB storage and 50M Request Units/mo. Beyond free tier, it costs $1 per 10M Request Units and $1/GiB storage per month. The Dedicated plan starts at $295/mo for a 3-node cluster (2 vCPU, 8 GiB RAM per node). For a typical OLTP workload with 1M queries/day, Serverless costs $10-30/mo. The value proposition is built-in multi-region replication — achieving the same with PostgreSQL requires pgBouncer, logical replication, and significant ops overhead. The cost trap: complex joins and full-table scans consume Request Units faster than simple key lookups.
Deep dive: Supabase
When to choose Supabase
Choose Supabase if you're building modern applications that need real-time features (live collaboration, chat, notifications), PostgreSQL SQL queries, and built-in auth without Firebase's vendor lock-in. It's ideal for startups and solo devs—the free tier is genuinely useful: 500MB database, 1GB file storage, and 50K monthly auth events. The open-source architecture means you can self-host if Supabase ever becomes too expensive or unreliable. Supabase is the WRONG choice for static sites, simple blogs, or projects that don't need a database—you're overpaying for a data engine. The free tier has gotchas: projects pause after 1 week of inactivity, so it's not suitable for production apps unless you pay. Edge functions are limited (Node.js-only, limited dependencies), so if you need Python or heavy compute, look at Vercel or Lambda. Real-time subscriptions are great for user-facing features but add complexity and can get expensive at scale ($4/month per 1M realtime events).
Real-world use case
A founder built a real-time collaborative whiteboard app using Supabase's free tier: PostgreSQL for drawing data, auth for user management, and realtime subscriptions for live syncing. Development took 3 weeks because Supabase's JavaScript client made auth + database + realtime easy. Launch day: 200 beta users, freemium model (5 boards per user, pay $5/month for unlimited). Month 1 costs: $0 (free tier). Month 2: traffic exceeded free tier limits (database grew to 600MB); upgraded to Pro ($25/month). At 500 paid users ($5/month each), revenue was $2,500/month; Supabase cost was $25/month. The pricing math worked beautifully. If she'd used Firebase, vendor lock-in would've been higher, and Postgres SQL flexibility would've been lost. The real-time feature (10K concurrent users syncing) cost her an extra $200/month in realtime events by month 6, but that was still <1% of revenue.
Hidden gotchas
Supabase's free tier pauses projects after 7 days of inactivity—projects are frozen, databases reset, and cold starts hurt. Many developers are shocked to find their free project gone after a vacation. Pro tier pricing ($25/month) includes 500K realtime events; overages are $0.04 per 100K events—a popular app hits $500+ in surprise overages. Database backups on free tier are limited to the last 7 days; Pro tier gets 30 days. Restore operations aren't self-service; they require support tickets. Self-hosting Supabase is documented but complex: you need Docker, Kubernetes, and 2+ hours of setup. The authentication defaults are opinionated—if you need SAML, LDAP, or non-standard OAuth flows, you'll hit limitations. Edge functions (Deno-based) have strict limits: 10 second timeout, no native PostgreSQL connection pooling, and dependency issues (some npm packages won't work). Row-level security (RLS) is powerful but has a learning curve; misconfigured policies silently fail, returning empty rows instead of errors. Realtime subscriptions aren't designed for high-frequency updates (>100Hz); you'll hit performance cliffs. Rate limiting for APIs isn't clearly documented; high-concurrency apps might get throttled unexpectedly. Cold starts on edge functions are 1-2 seconds, much slower than Vercel.
Pricing breakdown
Supabase's free plan includes 500 MB database, 1 GB file storage, 50 MB bandwidth, and 500K Edge Function invocations. The Pro plan at $25/mo adds 8 GB database, 100 GB file storage, and 250 GB bandwidth. Beyond included limits: database is $0.125/GB, bandwidth is $0.09/GB, storage is $0.021/GB. At moderate scale (50K MAU, 20 GB database), expect $40-80/mo. The advantage: Postgres + Auth + Storage + Edge Functions bundled at roughly 60% the cost of running separate services. The cost trap: database compute is tied to your plan tier — CPU-heavy queries on the free/Pro plans hit performance ceilings.
Should You Use CockroachDB or Supabase?
For most teams, CockroachDB is the better default: it offers truly distributed (no downtime) and is freemium (from $0 (free tier 5GB)). Choose Supabase instead if full postgres with sql matters more than complex operations. There is no universal winner — the right pick depends on your budget, team size, and whether you value truly distributed (no downtime) or full postgres with sql more.
Choose CockroachDB if…
- •Truly distributed (no downtime)
- •Postgres-compatible
- •Multi-region out of the box
Choose Supabase if…
- •Full Postgres with SQL
- •Built-in auth and storage
- •Open source
