Comparison
PgBeam vs Neon
Neon is serverless Postgres with branching and a low-latency driver. PgBeam is not a database: it is a policy and audit gateway that secures agent access to any Postgres, including a Neon database.
Neon: Neon is a serverless Postgres provider with database branching and a low-latency HTTP and WebSocket driver.
Neon and PgBeam are not the same kind of product, and they are not exclusive. Neon is a place to host Postgres. PgBeam is a gateway that secures how an AI agent reaches Postgres, on any host, including a Neon database. If you run on Neon and want agent guardrails, you use both.
PgBeam vs Neon, side by side
| Capability | PgBeam | Neon |
|---|---|---|
| Hosts the database | No (gateway) | Yes (serverless Postgres) |
| Database branching | Branch dry-runs for migrations | Yes (a core feature) |
| Agent policy (read-only, allowlists, budgets) | Yes, at the wire | No |
| PII masking | Yes | No |
| Per-statement audit trail | Yes | No |
| Hosted MCP endpoint with policy | Yes | No |
| Connection pooling | Yes | Yes (built in) |
| Query caching | Yes (TTL + SWR) | No |
| Works with non-Neon Postgres | Yes (any host) | Neon-hosted only |
A gateway, not a database
Neon decides where your data lives and how it scales. PgBeam decides what an agent is allowed to do with that data. It parses every statement and enforces read-only, allowlists, masking, and budgets at the wire, then records each one in an audit trail. Neon, like other database providers, guards its own hosting, not the agent's behavior across hosts.
That is the wedge: PgBeam's enforcement reaches databases a database vendor cannot, because it sits in the wire protocol rather than inside one provider's platform. The same policy covers a Neon database, an RDS instance, and a self-hosted Postgres at once.
Use them together
Point PgBeam at your Neon connection string, issue a scoped agent credential, and the agent reaches Neon through a policy engine with masking and audit. Your application keeps connecting to Neon directly. Repeated agent reads can be cached at the proxy to keep load off the database.
When Neon is the better fit
Neon is a full serverless Postgres platform with branching, scale-to-zero, and its own low-latency driver. PgBeam is not a database and does not replace it. If you need a place to run Postgres, that is Neon's job; if you need to govern agent access to it, that is PgBeam's.
