PGX is an AGPL-3.0 Rust runtime that gives every AI agent its own disposable Postgres database from one self-hosted process — no Docker, no per-DB provisioning.
Yes, PGX (Postgres for agents) is open source under the AGPL-3.0 license.
PGX core is free and open source (AGPL-3.0, beta) — self-host it on Mac or Linux with no Docker; a separate managed companion, PGRun, offers hosted branches, but PGX itself has no paid tier. (free).
Yes, PGX (Postgres for agents) can be self-hosted (the source is available under the AGPL-3.0 license).
An **AGPL-3.0 Rust runtime** that holds **thousands of isolated, disposable Postgres databases in one process** — tagline "Postgres for agents. One runtime. Thousands of Postgres databases." Instead of pointing every AI agent at one shared instance (contention and cross-contamination) or paying to provision a managed database per agent, PGX hands each agent its own throwaway Postgres DB. It self-hosts natively on **Mac and Linux with no Docker**.
Multi-agent GTM automation keeps hitting the same wall: agents need somewhere to write, but one shared database means contention and cross-contamination, and provisioning a managed DB per agent gets expensive fast. PGX is the own-your-stack answer for the sandbox/testing layer — a self-hosted runtime that gives each agent its own isolated, disposable Postgres database from a single process, on your own Mac or Linux box with no Docker. The honest read: it is beta and explicitly not crash-safe, so it is for ephemeral and test workloads, not a production system of record; every efficiency number is the maintainer's own; and the AGPL-3.0 copyleft is a real consideration for commercial teams whose use is network-facing. What is verified is what governs adoption: AGPL-3.0 read from the LICENSE file, the disambiguation from the well-known jackc/pgx, and a documented no-Docker self-host path on Mac and Linux.
