The short version

  • Each has a real cost: RavenDB the free Developer licence bars commercial use and expires every 6 months, requiring renewal; 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.
  • They diverge on capability: RavenDB covers ACID Transactions, Xata covers Copy-on-write branching.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

RavenDB

  • The free Developer licence bars commercial use and expires every 6 months, requiring renewal
  • The free Community licence caps a customer at 60 cores and forces you to stay on the latest major version
  • The Professional licence is limited to a single database, a 5 node cluster, 40 cores and 240 GB RAM
  • Sharding across nodes, ETL to OLAP, Elasticsearch and Kafka, and data archival are Enterprise only
  • Enterprise and AI licence pricing is contact us only with no published rate

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.

Answered from the vendors’ own pages

RavenDB: Is RavenDB free or open source?

RavenDB is open source under the AGPLv3 license and available on GitHub. It also offers a free developer license with enterprise-level features limited to 9 cores, 36GB max RAM, 3 nodes, and non-commercial use.

Source
Xata: 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.

RavenDB: Can I use RavenDB commercially for free?

RavenDB offers a free Community License that permits commercial deployment with unlimited databases and sizes, subject to a 60-core maximum per customer and requirement to run the latest major version.

Source
Xata: 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.

RavenDB: What commercial licensing options does RavenDB offer?

RavenDB offers Professional, Enterprise, and AI tiers for commercial use. Pricing for these tiers requires contacting their sales team at [email protected].

Source
Xata: 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.

RavenDB: Does RavenDB offer a cloud hosting option?

RavenDB Cloud provides a fully managed cloud database with maintenance, failover, and backups included. Pricing is available at cloud.ravendb.net/pricing.

Source
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.

RavenDB: Is there a refund window if I purchase RavenDB?

RavenDB offers a 30-day refund window for purchased licenses.

Source
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.
