ZeroDB vs Neon — AI Database vs Serverless Postgres
Neon is serverless Postgres with exceptional branching and cold-start performance. ZeroDB is the complete AI data layer — vectors, NoSQL, files, agent memory, and MCP in a single product. Choose the right foundation for your stack.

Why AI teams choose ZeroDB over Neon
Complete AI data layer, not just Postgres
Neon is serverless Postgres done exceptionally well — instant branching, scale-to-zero, and lightning-fast cold starts make it the best managed Postgres option available. ZeroDB goes further: vectors, NoSQL documents, file storage, agent memory, and MCP are first-class citizens, not extensions you configure separately.
MCP built-in, not an extension
Neon has pg_vector for similarity search. ZeroDB ships with two MCP servers — a 6-tool memory server and a 69-tool full database server. Connecting AI agents in Claude, Cursor, or any MCP host takes one config line. No pg_vector tuning, no embedding pipeline to wire up.
Agent memory as a first-class primitive
ZeroMemory gives agents the ability to remember, recall, and forget information across sessions — with automatic entity extraction, memory scoring, and decay. Neon stores your data in rows; your application code is responsible for making it useful to agents. ZeroDB handles that layer natively.
One bill instead of four
A typical AI app on Neon reaches for Pinecone (vectors), S3 (files), Redis (cache), and a custom memory layer before anything ships. ZeroDB consolidates all of those into a single product at a fraction of the combined cost. Neon is a great database; ZeroDB is the entire data infrastructure.
Frequently asked questions
ZeroDB vs Neon for AI — which should I choose?
It depends on your primary workload. If you are building a traditional web app with relational data and want the best serverless Postgres experience — branching for dev/staging, scale-to-zero, instant cold starts — Neon is excellent. If your app is AI-first (agents, RAG, vector search, persistent memory) and you want a purpose-built data layer that handles all of those without assembling four separate services, ZeroDB is the better fit. Many teams use Neon for their application database and ZeroDB for their AI data layer.
Neon vs Supabase vs ZeroDB — what is the difference?
Neon and Supabase are both managed Postgres platforms, but with different emphases. Supabase adds authentication, real-time subscriptions, and storage on top of Postgres. Neon focuses on serverless compute with instant branching and very fast cold starts. ZeroDB is not a Postgres platform — it is an AI-native database combining vectors, NoSQL, relational tables, file storage, agent memory, and MCP into one product. If you are evaluating Neon vs Supabase for a standard SaaS app, either works well. If you are building an AI application, ZeroDB covers capabilities neither of them offer natively.
Does ZeroDB support branching like Neon?
ZeroDB does not offer Git-style database branching the way Neon does — that is a standout feature of Neon's architecture. ZeroDB supports environment namespaces and snapshot-based cloning for staging workflows. If instant database branching for preview deployments is a hard requirement, Neon has the best implementation in the industry.
Can I use ZeroDB and Neon together?
Yes, and many teams do. A common pattern is to use Neon as the application Postgres database (user accounts, transactions, structured business data) and ZeroDB as the AI data layer (vector search, agent memory, document store, file storage). Both have REST APIs and framework-agnostic SDKs, so they compose cleanly.
How does ZeroDB pricing compare to Neon?
Neon's free tier offers 0.5 GB storage and limited compute. Paid plans start at $19/month. ZeroDB's free tier covers vectors, NoSQL collections, files, and memory with generous limits. Paid plans start at $15/month. The more meaningful cost comparison is total infrastructure spend: ZeroDB replaces Neon plus a vector database plus object storage plus a memory service. For AI-heavy apps that stack grows quickly.
