The Verdict
Fauna is built for serverless developers and jamstack apps, with a focus on acid-transactions and document-relational. Xata targets developers and startups and leads with serverless-database and full-text-search.

Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Fauna offers broader built-in capabilities (7 features vs 6), while Xata takes a more focused approach — which can mean a simpler, faster onboarding experience.
