Zilliz Cloud (Milvus) plans
| Plan | Price | What it covers |
|---|---|---|
| Free (Serverless) | $0/month | Free serverless tier including ~5GB storage and a monthly vCU allowance; suitable for prototyping. Collections unlimited. |
| Serverless | Pay-as-you-go (from ~$0.35/M vCU) | Pay-per-operation model charged on read/write resource consumption plus storage; best for variable/low-traffic workloads. |
| Dedicated | From ~$99/month (compute + storage) | Reserved compute units (CU ~= 1 vCPU + 4GB RAM) at pay-as-you-go rates; 99.95% uptime SLA, production-grade performance and isolation. |
| Business Critical (BC) | Custom | Added Oct 2025 for teams with stringent security/compliance needs; enhanced isolation, support, and resilience. |
| BYOC (Bring Your Own Cloud) | Custom | Zilliz Cloud control plane operating inside the customer's own cloud account/VPC for data-residency and compliance requirements. |
- Cost is the most cited complaint, managed pricing can be far more expensive than self-hosting Milvus on a cheap VPS for small/hobby projects
- vCU / CU-hour + tiered-storage billing model can be hard to forecast and reason about

Supabase Vector (pgvector) plans
| Plan | Price | What it covers |
|---|---|---|
| Free | $0/mo | 2 active projects, 500 MB database storage each, 50,000 MAU; pgvector available; projects paused after 1 week of inactivity. No uptime SLA. |
| Pro | $25/mo per org | 8 GB database, 100 GB storage, 100K MAU included; includes $10/mo compute credits (covers one Micro instance); usage-based overages; daily backups. |
| Team | $599/mo per org | Pro features plus SOC2 / ISO 27001, SSO, audit logs, 14-day PITR backup retention, and priority support. |
| Enterprise | Custom | Custom pricing with designated support, HIPAA, BYO-cloud options, and the 99.9% uptime SLA with service credits. |
- Good query latency requires the index to fit in RAM, pushing you to larger, costlier compute add-ons
- Performance degrades and p99 tail latency grows beyond roughly 5–50M vectors on a single node, not ideal for billion-scale search
- A real 99.9% uptime SLA is Enterprise-only; lower tiers get no contractual guarantee
