Xata vs Supabase

Branches with real data. Supabase branches copy your schema but none of your data. Every branch starts empty, which means your tests run against synthetic seeds, not production-realistic scenarios. Xata creates true copy-on-write branches that include full production data, so your staging environment actually reflects production.

Built-in anonymization. Supabase has no anonymization capability. If you need to share production data with development teams, you are on your own. Xata auto-detects PII and anonymizes data during replication — every branch starts with clean, realistic data that preserves referential integrity.

• Branches with real data
• Built-in PII anonymization
• Multi-cloud and BYOC
• 100% vanilla PostgreSQL
• Zero-downtime migrations via pgroll
• No vendor lock-in

Vanilla Postgres, no lock-in. Supabase layers proprietary extensions on top of Postgres — auth, storage, realtime, and edge functions are all Supabase-specific. If you leave, you lose those integrations and must rewrite your application layer. Xata runs unmodified Postgres. Your application connects via standard Postgres wire protocol. If you ever want to leave, you take your database with you.

Multi-cloud and BYOC. Supabase runs exclusively on AWS. Xata runs on AWS, GCP, Azure, and Hetzner — and offers a full Bring Your Own Cloud (BYOC) option where Postgres runs in your own cloud account while Xata manages operations. Your data never leaves your infrastructure.

Zero-downtime schema changes. Supabase provides no native migration tooling. Xata includes pgroll, an open-source schema migration tool that serves old and new schema versions in parallel. No downtime, no long table locks, no broken deployments.
