Category: Vector DatabaseVerified for 2025
Top Recommended Replacements
Qdrant
Best High-Performance Alternative
Why we like it
Written in Rust for extreme efficiency; supports 'Binary Quantization' (compression) to reduce RAM usage by 30x; runs as a single Docker container; trusted by X (Twitter) and Grok.
Keep in mind
Self-hosting requires managing your own disk/snapshots; cloud version is paid.
pgvector (Postgres)
FREEBest for Simplicity
Why we like it
The biggest trend of 2025: just add vector search to your existing Postgres database; zero new infrastructure to manage; ACID compliance; keeps your vectors next to your business data.
Keep in mind
Slower than specialized DBs like Qdrant at massive scale (100M+ vectors); requires tuning HNSW indexes manually.
Chroma
FREEBest for AI Agents / Local
Why we like it
The default choice for Python developers and LangChain users; runs entirely locally or in-memory (no server needed); perfect for prototyping and single-user AI agents.
Keep in mind
Not designed for massive distributed scale; the 'hosted' cloud version is still maturing.
Milvus
Best for Enterprise Scale
Why we like it
The 'Heavy Duty' option designed for billions of vectors; distinct storage/compute separation allows massive scaling; used by heavy hitters like eBay and IKEA.
Keep in mind
Complex architecture (requires Kubernetes, Etcd, MinIO, Pulsar) to run self-hosted; overkill for small apps.
Weaviate
Best for Hybrid Search
Why we like it
Built-in 'Hybrid Search' (combining Vector + Keyword search) is best-in-class; modular architecture allows you to plug in different ML models easily.
Keep in mind
Memory-hungry compared to Qdrant (written in Go vs Rust).
LanceDB
Best Serverless / Embedded
Why we like it
A new breed of database that runs *embedded* in your application (like SQLite for vectors); extremely fast; stores data on S3/disk rather than expensive RAM.
Keep in mind
Newer ecosystem; fewer integrations than Pinecone.
Supabase Vector
FREEBest for Frontend Devs
Why we like it
A managed wrapper around pgvector; provides an instant, auto-scaling vector DB with a beautiful UI and easy JS client; free tier includes 500MB database.
Keep in mind
It is ultimately just Postgres, so it shares pgvector's scaling limits at the very high end.
Redis (Vector Search)
FREEBest for Real-Time
Why we like it
If you already use Redis, you can turn on vector search; extremely low latency (in-memory); perfect for real-time recommendation engines/caching.
Keep in mind
RAM is expensive; storing millions of vectors entirely in RAM is costly.
