The short version

  • RAD Studio is a cross-platform IDE.
  • Xata has a free plan, then $1/mo; RAD Studio starts at $2000/mo.
  • Where RAD Studio falls short: professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax.

Where each one falls short

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

RAD Studio

  • Professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax
  • Enterprise edition steps up to $3,400 license plus $1,199 maintenance, and Architect edition to $4,416 license plus $2,183 maintenance
  • The perpetual license only entitles the buyer to updates for one year; continued access to new updates and upgrades requires an annually renewable Update Subscription

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

RAD Studio: How much does RAD Studio cost?

RAD Studio uses perpetual licensing: Professional Edition $2,000 perpetual license + $599 first year maintenance ($2,599 total + tax). Enterprise Edition $3,400 license + $1,199 maintenance ($4,599 total + tax). Architect Edition $4,416 license + $2,183 maintenance ($6,599 total + tax).

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.

RAD Studio: What is the difference between RAD Studio editions?

Professional Edition ($2,599 total + tax) targets individual developers. Enterprise Edition ($4,599 total + tax) adds multi-tier app capabilities. Architect Edition ($6,599 total + tax) includes advanced database and cloud features. All three include perpetual licenses.

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.

RAD Studio: Does RAD Studio offer Kai AI integration and discounts?

Yes, adding Kai AI to any edition provides discounts: 25% off Professional ($2,136 + tax), 30% off Enterprise ($3,394 + tax), and 40% off Architect ($4,109 + tax). This promotion is active through August 31, 2026.

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.

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.
