CAA record generator

How to use

Enter only the settings you need, generate the result, then review it before publishing to DNS, HTTP headers, or your site files.

1. Enter the source values or choose the directives you need.
2. Generate the configuration string and read it once before copying.
3. Publish it only after comparing it with your DNS, server, or vendor documentation.

Before publishing

These generators help with syntax and assembly, but they do not verify the live DNS zone, server configuration, or crawler behavior. Check the final value in the service where it will actually be published.

Why this is separated into a tool

Configuration strings are easy to mistype and often combine several optional directives. A small dedicated generator makes the final value easier to inspect, copy, and compare with vendor documentation.
