Feature | ![]() | ![]() |
---|---|---|
Deployment Model | Managed Cloud SaaS | Self-hosted / Cloud (Alpha) |
Starting Price | $70/month | Free (self-hosted) |
Setup Time | 15 minutes | 5 minutes |
Max Vectors | 100B+ | ~10M (soft limit) |
Query Latency | <50ms p99 | <100ms (local) |
High Availability | Built-in (99.99% SLA) | Manual setup required |
Language Support | Python, JS, Go, Java | Python, JS |
Open Source | No | Yes (Apache 2.0) |
Built from the ground up as a distributed cloud service with pod-based architecture that separates compute and storage for optimal performance.
Key Insight: Pinecone abstracts all infrastructure complexity, allowing teams to focus solely on application development.
Designed as an embedded database that runs alongside your application, minimizing latency and maximizing developer control.
Key Insight: Chroma prioritizes simplicity and developer experience over distributed system complexity.
Note: Chroma performance is based on local deployment. Network latency would add 20-50ms for client-server mode.
Pinecone
Linear performance up to 100B+ vectors with automatic sharding and load balancing
Chroma
Performance degrades beyond 10M vectors; requires manual sharding for larger datasets
Pinecone
Handles thousands of concurrent connections with automatic scaling
Chroma
Limited by single-node architecture; ~50-100 concurrent connections
Scale | Pinecone | Chroma (Self-hosted) |
---|---|---|
Prototype (100K vectors) | Free tier | $0 (local) |
Small (1M vectors) | $70/month | $20/month (VPS) |
Medium (10M vectors) | $280/month | $100/month + DevOps |
Large (100M vectors) | $840/month | Not recommended |
Enterprise (1B+ vectors) | Custom pricing | Use distributed solution |
For Pinecone:
For Chroma:
pip install pinecone-client import pinecone pinecone.init(api_key="your-key") index = pinecone.Index("my-index") index.upsert(vectors)
pip install chromadb import chromadb client = chromadb.Client() collection = client.create_collection("my-collection") collection.add(embeddings=vectors)
A marketplace with 50M+ products needs:
Pinecone handles this without any DevOps overhead
Fortune 500 company requirements:
Pinecone provides enterprise guarantees out of the box
Startup building an MVP needs:
Chroma enables rapid prototyping with no overhead
University research requirements:
Chroma's open source nature perfect for research
When your Chroma prototype outgrows single-node limits:
For non-critical workloads under 10M vectors:
⚠️ Important: Always maintain parallel systems during migration and thoroughly test performance before switching production traffic.
Requirement | Recommended | Reasoning |
---|---|---|
Production with SLA needs | Pinecone | Guaranteed uptime and support |
Prototyping/Development | Chroma | Fast iteration, no costs |
100M+ vectors | Pinecone | Chroma hits scaling limits |
Budget < $50/month | Chroma | Self-host for free |
Real-time updates needed | Pinecone | Instant index updates |
Full data control required | Chroma | Open source, self-hosted |
Multi-region deployment | Pinecone | Built-in global distribution |
Pinecone excels as a production-ready vector database that eliminates operational complexity. Its managed service model, guaranteed SLAs, and ability to scale to billions of vectors make it the clear choice for enterprises and startups that need reliability over customization.
Bottom Line: Choose Pinecone when uptime, scale, and speed matter more than cost.
Chroma shines in development environments and smaller-scale applications. Its simplicity, Python-native design, and zero-cost self-hosting make it perfect for prototypes, research projects, and applications under 10M vectors.
Bottom Line: Choose Chroma for rapid development, full control, and cost-sensitive projects.
Start with Chroma for prototyping and development. Once you validate your use case and need production-grade reliability or scale beyond 10M vectors, migrate to Pinecone. This approach minimizes initial costs while ensuring a smooth path to scale.
Our experts can help you implement the right vector database solution for your specific use case.
