Finding a slow query on a Postgres branch, without leaving the terminal. xata branch query-insights ranks that branch's statements by cost, flags the slow ones, and prints the command to inspect any of them. Logs and instance metrics are one command away.

If every agent and PR gets its own Postgres branch, you're scripting those, not clicking them. So the CLI output has to be parseable. Now it is: piped output is clean plain text, xata branch list --json for anything automated. Boring, but that's the point at scale.

2TB+ Postgres. Branch it in seconds, query it, delete it. xata scratch (new Xata CLI cmd) forks a disposable branch off your real DB, drops you into psql or runs SQL inline, tears it down on exit. Demo 👇

pgstream v1.1.1: the replication path now binds and escapes identifiers, slot names, and plugin options, so a crafted name can't break out onto the target. Backported to v0.9.15. Plus wider snapshot restore coverage. github.com/xataio/pgstr...

Introducing the Xata GitHub App. Connect a repo to your Xata project and every pull request gets its own isolated Postgres branch off main, with production-like data, ready in seconds when the PR opens and gone when it closes.

Xata is now on Google Cloud. Spin up an isolated Postgres branch from your production data in 3 seconds, in-region in us-central1 (Iowa). Every coding agent, PR, and CI run gets its own production-like database. No shared staging, no migration.

New Xata region: AWS us-west-2 is live. West coast agents and CI can now run their Postgres branches next to their compute. Same instant branching, scale-to-zero, and pricing as us-east-1. xata.io/docs/changelog#aws-us-west-2-region-support

Very proud that we are be able to sponsor pgBackRest and therefore help with the continuing maintenance of the project. It's rock solid and fast, the properties you want from the backup solution. It's the safety net we offer to all @xata.io customers.

Xata - Postgres at Scale@xata.io · last mo.

We run 100% vanilla Postgres. No fork, no modifications. A deliberate decision from day one to build a platform around Postgres, with branching at the storage layer instead of inside the database. This means the whole Postgres ecosystem just works with Xata.

Branching gives every engineer and every agent their own Postgres. Now every branch has its own logs. Read, filter, and search them in the console, or match a pattern in one click. Same logs in your terminal with xata branch logs.

DeltaX, our open-source timeseries and columnar extension for Postgres, just shipped v0.2.1, mostly analytics performance work. A few engineering bits worth sharing:

Postgres CDC has always been a thing you babysit: a CLI in a screen session, secrets in a config file, a pipeline that breaks on the next ALTER TABLE. pgstream v1.1.0 is a step toward running it as a service. K8s probes, JSON logs, and schema changes that flow to the target. xata.io/blog/pgstrea...

pgstream v1.1.0: running Postgres replication as a service by Noémi Ványi

What's new in pgstream v1.1.0: env vars in YAML config, JSON logs, Kubernetes health probes, custom TLS for OpenSearch, and fixes for composite primary keys.

Introducing the latest in Postgres for agentic workloads. Agents can now branch or wake your Postgres database instantly.

Today, Xata CEO Monica Sarbu joined the Berlin Buzzwords panel "The Agent Era: How AI Agents Are Reshaping Data Platforms," alongside speakers from Snowflake, Elastic, and MotherDuck, on what breaks when agents become the most demanding users of data platforms.

That sidebar full of "untitled query (3)" you never keep? We reworked the Xata query editor: new queries open as drafts, run and discard, nothing saved. Plus Run selected, per-statement tabs, autosave with AI naming. xata.io/blog/query-editor-v2-a-better-way-to-write-sql-in-xata-console

We've rebuilt the query editor from the ground up. The new version is faster, smarter, and easier to use.

We rebuilt how every Postgres branch on Xata is observed: out of a central observability vendor, into a per-cell VictoriaMetrics stack. Nothing crosses cells, so one cell's observability can't break another's. Six weeks of work, no user-visible downtime. Full write-up: xata.io/blog/how-we-...

There’s something I’ve been feverishly working on, and I just turned the repo public: pg_deltax, a fast time-series extension for PostgreSQL. Basically an Apache-licensed Timescale alternative. Please give it a star: github.com/xataio/deltax

pgstream v1.0.2 shipped. Stream-mode WAL batching means post-snapshot catch-up stops stalling on bulk-INSERT and DELETE tables (Postgres sink only for now; UPDATE still goes one at a time). Decode-time table filtering inside Postgres via wal2json.

Every Xata Postgres branch now has a managed PgBouncer endpoint, in the same memory envelope as the database. Auto-tuned to 0.9 of max_connections. 10,000 client connections per branch. Hibernates with the branch. Append `-pooler` to your branch ID. Writeup: xata.io/blog/a-conne...

Postgres connection pooling per branch | Xata by Noémi Ványi

Every Xata Postgres branch includes a built-in PgBouncer pooler in transaction mode. Tuned for serverless and edge, scales to zero with the branch.

I’ve written a blog post on why and how we built our own distributed storage engine. We’re calling it Xatastor and enables us to scale to a huge number of Postgres instances and branches. It’s based on ZFS and NVMe-oF as key technologies. xata.io/blog/xatasto...

Engineers are writing most of their code with AI now. The software engineering profession is not over. The job has split: AI codes, humans engineer. A thread on what changed and what didn't:

Two new per-branch settings in Xata: 1. Postgres minor version upgrades. Pick your target in the UI or CLI, the API validates it, branch restarts. 2. Password rotation. `xata branch rotate-password` generates a new password, active in under 1 second. Existing connections keep working.

Code review is a negotiation. The submitter trades shipping speed for the reviewer's confidence that this won't cause pain later. Most new coders don't realize this. They optimize for "does it work" when they should optimize for "can my reviewer approve this safely."

Remote teams don’t get stronger from more meetings. They get stronger from time together that feels human. At Xata, Club Xata France 2026 was built around good conversations, shared meals, walks, and the unplanned moments in between. Check the full story here: xata.io/blog/club-xa...

Xata is now open source. Apache 2.0. Postgres platform with Copy-on-write branching at the storage layer. Copy a TB-sized database in seconds. Inactive copies scale to zero automatically. 100% vanilla Postgres.
