| Entry Paid Tier (Monthly) | $25 USD / mo | $25 USD / mo |
| Pricing & Cost Architecture | Free tier offers 2 managed projects with 500MB database storage (~250k vectors). Pro plan starts at $25/mo with 8GB storage and scalable compute add-ons. | Core engine is 100% free under BSD-3-Clause. Weaviate Cloud (WCD) provides a 14-day free sandbox, with serverless consumption tiers starting at $0.05 per 1,000 queries. |
| Key Engineering Insight | Allows developers to store relational application state, user authentication (Row Level Security), and high-dimensional vector embeddings inside a single ACID-compliant Postgres database. | Pioneered native Hybrid Search in vector databases, allowing developers to mathematically merge sparse BM25 keyword matching with dense HNSW vector similarity in one call. |
Strengths & Trade-Offs
Objective engineering evaluation of both platforms
Supabase Vector Evaluation
Key Advantages
- ✓ Combines vector search with full Postgres ecosystem: Row Level Security, ACID transactions, and relational joins
- ✓ Instant auto-generated client APIs (REST, GraphQL, real-time WebSockets) with zero backend boilerplate
- ✓ Permissive open-source stack with official Docker compose deployment for self-hosting on any VPS
Limitations & Trade-Offs
- ✕ Free tier projects pause automatically after 7 days of inactivity (resumed upon dashboard login)
- ✕ Dedicated standalone C++ vector stores can achieve higher raw QPS for multi-million vector datasets
Weaviate Evaluation
Key Advantages
- ✓ Native Hybrid Search seamlessly merging sparse BM25 keyword scoring with dense vector cosine distance
- ✓ Modular architecture supporting direct vectorization with OpenAI, Cohere, HuggingFace, and local Ollama models
- ✓ Rich GraphQL and RESTful APIs with flexible schema definitions and built-in multi-tenancy support
Limitations & Trade-Offs
- ✕ Higher baseline RAM utilization due to concurrently maintaining inverted text indexes and vector graphs
- ✕ Configuring external vectorizer microservice containers adds operational moving parts when self-hosting
