Burp Repeater

Burp Repeater is a tool that enables you to modify and send an interesting HTTP or WebSocket message over and over.

You can use Repeater for all kinds of purposes, for example to:

• Send a request with varying parameter values to test for input-based vulnerabilities.
• Send a series of HTTP requests in a specific sequence to test for vulnerabilities in multi-step processes, or vulnerabilities that rely on manipulating the connection state.
• Manually verify issues reported by Burp Scanner.
• Use AI-powered prompts to investigate behavior or look for security issues.

Repeater enables you to work on multiple messages simultaneously, each in its own tab. Any modifications you make to a message are saved in the tab's history. You can easily manage large numbers of open tabs with the grouping function. For HTTP requests, you can also add notes to each tab.
