[H1] One Postgres,thousands of branches
Give every agent its own Postgres branch with real data, instantly, without killing your budget.Get startedRead the docs
[H2] Agents don't need a better database. They need thousands of them.
Agents can’t share a staging database. Each needs an isolated Postgres branch with real data. With Xata, spin up tens of thousands of databases for the cost of one.

[H2] Agent-driven development
Every agent run and CI job gets its own Postgres with production data. Spin up, run, preview, and discard thousands of times per hour.
[H2] Simulation and RL training
Every RL episode needs a fresh Postgres from a known state. Snapshot a baseline, spawn thousands of copies, run in parallel, discard, repeat.
[H2] Multi-tenant agent platforms
Every RL episode needs a fresh Postgres from a known state. Snapshot a baseline, spawn thousands of copies, run in parallel, discard, repeat.
[H2] Instant branching
Branch a live Postgres database within seconds, regardless of size. By separating storage from compute, each branch references parent data and only stores deltas, allowing thousands of branches to be created without multiplying storage.
[H2] Copy-on-write
Full clones without the cost. Each branch starts with the same parent's data and stores changes only.Developmentprod-cloneDevelopment /rl/episode-001Development /rl/episode-002Development /sim/load-testDevelopment /sim/regression
[H2] Scale to zero
Run branches only when needed. When idle, they hibernate and use no compute.280 branchesActive: 280Idle: 0Compute$33.60/hr

Xata is currently the best way to run the pg_duckdb extension in the cloud. The platform’s flexibility and API access make Xata the perfect PostgreSQL partner for us.Jordan TiganiCEO, MotherDuck
[IMG: logo-Chris Windsor]
Xata was an easy choice for our team because of how straightforward the entire platform is, while simultaneously providing a suite of adequate features that we need. The Xata team has also been super responsive and more importantly quick to resolve the hiccups that we brought upon ourselves.Chris WindsorLead Software Engineer, Safestreets

[H2] Documentation Index
Fetch the complete documentation index at: https://xata.io/docs/llms.txtUse this file to discover all available pages before exploring further.Xata is a modern PostgreSQL platform built for engineering teams that want to build faster and ship with confidence. It transforms development workflows by giving teams instant, safe access to real production data (PII removed), without the risks or costs of maintaining production clones.
With Xata, every pull request or coding agent can instantly create its own isolated database branch with anonymized production data. Branches use copy-on-write technology, so the data is shared with the parent instead of being fully copied. That’s why creating a new branch is instant, whether your database is 1 TB or 5 TB. Branches are also very cost-efficient: you only pay for compute while storage is shared, and they can automatically hibernate when not in use to save even more.
You can start using Xata just for your development workflows, keeping your production database exactly where it is. This setup allows your team to branch, test, and experiment safely with real data without changing your existing infrastructure. Once your team is ready, Xata can power both development and production for a unified workflow and consistent performance.
