Overview
Zilliz is a US-based enterprise software company and the creator of Milvus, the world's most widely adopted open-source vector database with over 44,000 GitHub stars and 100 million+ downloads. Founded in 2017 by Charles Xie, Zilliz offers two primary products: the open-source Milvus for self-managed deployments, and Zilliz Cloud, a fully managed, multi-cloud vector database service built on Milvus. Zilliz Cloud is available on AWS, GCP, and Azure across 30+ regions, with deployment options spanning serverless, dedicated, and Bring Your Own Cloud (BYOC) modes. The platform targets enterprises building AI applications requiring high-performance vector search at scale—from RAG pipelines and recommendation engines to fraud detection and drug discovery. Zilliz is named a Leader in the Forrester Wave Vector Database Providers Q3 2024 and serves 10,000+ enterprise customers.
Zilliz provides open-source (Milvus) and fully managed (Zilliz Cloud) vector database technologies purpose-built for AI applications requiring high-performance embedding similarity search at billion-vector scale. Its proprietary Cardinal Search Engine powers Zilliz Cloud's performance advantages, while its AutoIndex feature removes manual tuning. The platform supports serverless, dedicated, and BYOC deployments across major clouds, integrates with leading AI frameworks, and delivers enterprise-grade security, compliance, and observability tooling.

Alternatives in Search & Vector Databases6
Zilliz positions as the enterprise-grade, fully managed vector database built on open-source Milvus, combining maximum retrieval performance (claimed 10x faster than self-hosted Milvus via its proprietary Cardinal Search Engine) with managed simplicity.
- Named a Leader in the Forrester Wave Vector Database Providers Q3 2024 and the only vendor to simultaneously earn G2's 'Highest Performer' and 'Easiest to Use' in the Summer 2025 Vector Database Grid Report.
- Zilliz differentiates on open-source credibility (Milvus), multi-cloud reach (AWS, GCP, Azure, 30+ regions), enterprise compliance depth (SOC2 Type II, ISO 27001, HIPAA-eligible, CMEK), and its BYOC deployment model for regulated industries—targeting teams who outgrow self-hosted Milvus or commodity serverless offerings like Pinecone.
Reviews
Praised
- Blazing-fast vector retrieval (sub-100ms for millions of vectors)
- Ease of use and quick onboarding via SDKs
- Comprehensive and clear documentation
- Seamless integration with LangChain and OpenAI embeddings
- Managed service eliminates infrastructure and ops burden
- Pay-as-you-go pricing accessible to individual developers
- Scalability from prototype to billions of vectors
- Open-source Milvus foundation reduces vendor lock-in risk
Criticized
- High cost for small or individual projects vs. self-hosting
- Manual chunked uploads required for very large datasets
- Some edge-case documentation gaps
- Advanced enterprise features locked to top-tier plans
Zilliz holds a 4.7/5 rating on G2 from 53 verified reviews (92% 5-star), recognized as both 'Highest Performer' and 'Easiest to Use' in G2's Summer 2025 Vector Database Grid Report. Users consistently praise blazing-fast query performance (sub-100ms for millions of vectors), ease of getting started via SDKs and documentation, seamless integration with LangChain and OpenAI embeddings, and the managed service's ability to eliminate infrastructure overhead. The most common criticism is cost at small or individual-project scale, where self-hosting is materially cheaper. Some users note friction with chunked large-file uploads.
Pricing
Zilliz Cloud offers four tiers.
- Free
$0, 5 GB storage, up to 5 collections. Serverless (Standard): pay-as-you-go based on vCU consumption, starting from $0/month. Dedicated Standard: from $99/GB/month; Dedicated Enterprise: from $155/month with 99.95% SLA, RBAC, SSO, private networking, and 24/7 support.
- Business Critical
custom pricing with 99.99% SLA, CMEK, HIPAA eligibility, PITR, and priority support. BYOC: custom pricing for self-infrastructure deployments. Cluster pricing by type: Performance-optimized from $65/million vectors/month; Capacity-optimized from $20/million vectors/month; Tiered-storage from $7/million vectors/month. Annual commit plans offer additional credits. Available via AWS, GCP, and Azure Marketplaces for cloud-spend drawdown.
Limitations
- Managed dedicated clusters can be costly for small projects or individual developers—G2 reviewers note that self-hosting on commodity infrastructure (e.g., Hetzner) can be significantly cheaper at small scale.
- Large-scale data uploads require manual chunking, which some users find cumbersome.
- Self-hosted Milvus configuration involves operational complexity that Zilliz Cloud resolves but at added cost.
- Free tier is limited to 5 GB and 5 collections.
- Advanced features (CMEK, PITR, continuous data protection) are gated to Business Critical tier requiring custom pricing negotiation.
