Apache 2.0 platform for running many Postgres instances on Kubernetes, with copy-on-write branching and scale-to-zero.

The short version
- Namespace is a developer infrastructure platform.
- Free plans on both; paid from $100/mo and $1/mo.
- Only Namespace lists GitHub Actions runners; only Xata lists copy-on-write branching.
- Where Namespace falls short: developer plan is pay-as-you-go only; minimum usage unclear.
- Prices and features on this page were last checked on 13 November 2026.
Where they differ
Only the attributes on which Namespace and Xata actually diverge.
Identical on both: starting price (Free), free tier (Yes).
Not yet recorded: pricing model for Namespace.

Xata

- Running managed-Postgres economics in your own cloud account where data residency or compliance rules out a third-party control planenot Namespace
- Consolidating many small, mostly idle Postgres databases onto shared infrastructure where scale-to-zero and bin-packing recover the idle costnot Namespace
- Testing a destructive migration against a copy of production without waiting for a full restore or paying for a duplicate of the storagenot Namespace
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Namespace
- Developer plan is pay-as-you-go only; minimum usage unclear
- Team plan $100/mo is competitive but usage limits may be tight
- Devbox pricing separate at $0.004/minute could add up quickly
- Enterprise plan requires custom sales conversation
Xata
- Self-hosting means operating Kubernetes and CloudNativePG, so the Apache 2.0 licence removes the vendor bill but replaces it with a platform team, and a database platform is not something a part-time operator maintains safely
- Copy-on-write branches are cheap to create but diverge as they are written to, so a long-lived branch carrying a heavy backfill quietly accumulates real storage and the cost arrives later than the decision that caused it
- Scale-to-zero means the first connection after an idle period pays a cold start, which is invisible in a busy production database and very visible in a demo, a staging environment or a cron job that runs once an hour
- The Xata sold before 2025 was a different product, a proprietary API and SDK layered over Postgres, so tutorials, blog posts and SDK examples from that era describe something that no longer exists and existing users had to migrate
- As a managed service it competes with RDS, Aurora and Cloud SQL, and it is a much smaller company, so procurement, certification coverage and the depth of the support bench behind a 3am corruption incident are all weaker than the incumbent even though the underlying Postgres is the same

Questions people ask
- Is Namespace or Xata better?
- Neither clearly leads. Namespace starts at Free and Xata at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Namespace or Xata?
- Namespace starts at Free and Xata at Free.
- Does Namespace or Xata run on more platforms?
- Namespace runs on Web, macOS, Windows, Linux. Xata runs on Web.
- Can I use Namespace for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Namespace best used for?
- Namespace is most often used for providing ai coding agents with cloud-based development environments, accelerating ci builds with faster github actions runners, distributing builds across teams with managed infrastructure, scaling development velocity for monorepo organizations. Of those, providing ai coding agents with cloud-based development environments and accelerating ci builds with faster github actions runners are not what Xata is typically brought in for.
- What can Namespace do that Xata cannot?
- Namespace covers Devboxes, GitHub Actions runners, Docker builds, Cross-invocation caching. Xata covers Copy-on-write branching, Scale-to-zero compute, Compute autoscaling and bin-packing, High availability with failover.
Answered from the vendors’ own pages
Namespace: How is compute usage metered on the Developer plan?
Developer plan uses pay-as-you-go billing. Devboxes bill at $0.004 per minute. Storage and caching services have separate usage-based fees. A 30-day free trial is available to test usage patterns.
SourceXata: Is it real Postgres or a compatible reimplementation?
Real Postgres. It runs upstream Postgres instances on Kubernetes via CloudNativePG, so extensions, the wire protocol and version upgrades behave as they do anywhere else.
Namespace: What is the difference between Team and Business plans?
Team ($100/mo) includes 100,000 unit minutes and 1,000 Docker builds with email support. Business ($250/mo) includes 250,000 unit minutes, 2,500 Docker builds, and high concurrency with a dedicated Slack channel.
SourceXata: Can I self-host the whole thing?
Yes. The platform is Apache 2.0 and designed for self-hosting a large number of Postgres instances on your own Kubernetes. Xata Cloud is the same platform run as a service.
Namespace: Can Namespace support AI coding agents?
Yes, Namespace Devboxes are specifically designed as feature-rich development environments for AI coding agents, with full tooling and performance optimization.
SourceXata: Does branching copy my data?
No. Branches are copy-on-write at the storage layer, so creating one is near-instant regardless of database size and storage is only consumed as the branch diverges from its parent.
Xata: Is this the same Xata I used a couple of years ago?
No. The earlier product was a proprietary database API with its own SDK and search layer. The current product is a Postgres platform, and material written for the old one does not apply.
Xata: What happens to a branch when the parent changes?
A branch is a point-in-time fork. Later changes on the parent are not propagated, so long-lived branches drift and need to be recreated rather than refreshed if you want current data.
