CockroachDB

Pricing | Plan a CockroachDB Serverless Cluster

• All cluster activity, including SQL queries, bulk operations, and background jobs, is measured in Request Units, or RUs. An RU is an abstracted metric that represents the compute and I/O resources used by a database operation. In addition to queries that you run, background activity, such as automatic statistics to optimize your queries or connecting a changefeed to an external sink, also consumes RUs

Xata

Pricing | Pricing (Docs)

• The storage size represents the amount of data stored in the transactional database. Database storage in Xata encompasses not only disk space but also I/O rates and compute resources. The listed price per GB combines the costs of the three components allocated to each workspace
• Free plan: 15 parallel requests (6 primary + 9 from replicas) to the database
• Free tier: Limited to 75 requests/second (qps)
• Additional Features
  • Elasticsearch integration
  • File attachments (2GB, S3 and Cloudflare's CDN)
  • Image transformations (10k)
  • 250 AI-powered questions per workspace
  • Free plan users can request data restoration from a daily backup through our support team

Pricing

Vercel Postgres

Pricing | Limits
