- Running managed-Postgres economics in your own cloud account where data residency or compliance rules out a third-party control planenot Blacksmith
- Consolidating many small, mostly idle Postgres databases onto shared infrastructure where scale-to-zero and bin-packing recover the idle costnot Blacksmith

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Blacksmith
- Per-minute pricing model requires estimating usage to predict costs
- macOS M4 pricing ($0.08/min) is significantly higher than GitHub Actions
- Docker layer caching and sticky disks are paid add-ons at $0.50/GB/mo
- Static IP add-on costs $100/IP/mo
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
Blacksmith: How much do Blacksmith runners cost compared to GitHub Actions?
Blacksmith offers 60-75% cost savings depending on OS. Ubuntu x64 costs $0.004/min vs GitHub at $0.012/min. All plans include 3,000 free minutes monthly.
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.
Blacksmith: Can I use Docker layer caching with Blacksmith?
Yes, Docker layer caching is available as an add-on at $0.50/GB/mo. Managed Docker layer persistence is included with the base service.
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.
Blacksmith: What is the SLA for Enterprise plans?
Enterprise Blacksmith plans include a 99.9% SLA guarantee along with 24/7 priority support, dedicated Slack channels, white-glove onboarding, and CI optimization support.
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.
