Neon

Overview

Neon is Serverless Postgres built for the cloud with native support for pgvector extension, enabling efficient vector storage and semantic search. Architecture separates compute from storage for serverless features.

Key Features

• Serverless Architecture: Separate compute and storage layers
• Instant Provisioning: Databases ready in seconds
• Autoscaling: Automatic scaling based on demand
• Scale to Zero: Automatic pause when idle to reduce costs
• pgvector Support: Native vector similarity search in PostgreSQL
• Branch-Based Development: Git-like branching for databases

Vector Search Capabilities

• Full pgvector extension support
• Store embeddings alongside regular data
• Vector similarity search with SQL queries
• Compatible with OpenAI and other embedding providers
• Elasticsearch-grade vector features in Postgres

Serverless Features

• Instant Provisioning: No waiting for database setup
• Autoscaling: Compute scales automatically with load
• Scale to Zero: No charges when database is idle
• Branching: Create instant database copies for development
• Time Travel: Point-in-time recovery
