R2 SQL query editor now in dashboard

You can now query your R2 Data Catalog tables with R2 SQL directly from the Cloudflare dashboard, without installing a CLI or wiring up a client. This makes it easy to explore your Apache Iceberg data, validate queries, and inspect results in one place.

To get started, go to R2 Data Catalog in the Cloudflare dashboard and select Query data to launch the built-in SQL editor. From there you can:

• Write and run queries interactively — Iterate on R2 SQL directly in the browser with syntax highlighting and autocomplete, instead of re-running commands through Wrangler or the REST API.
• Explore your data — Explore your namespaces and tables alongside the editor so you can discover what's queryable without leaving the page or using other tools.
• Understand results and performance — View result sets with per-query statistics, export them, and get helpful EXPLAIN outputs to see exactly how a query runs.

Note

Your R2 SQL credential is generated and stored for you and can be rotated in the R2 Data Catalog settings page.
