Rewrite rules

Rewrite rules let you change requests and responses on the fly before they reach the server or the UI.

What rewrite rules can do

Use rewrite rules to:

• Redirect requests to a different URL.
• Modify request headers, query params, cookies, or body.
• Modify response headers, body, or status code.
• Block requests entirely.
• Map requests to local responses (mocking).

Create a rule

1. Open Settings → Rewrite Rules.
2. Tap Add Rule.
3. Choose a Rule Type (redirect, modify, block, map).
4. Configure the Match criteria (exact, contains, wildcard, or regex).
5. Add one or more Actions.
6. Save and enable the rule.

Matching and priority

• Rules match on the request URL.
• Use priority to control evaluation order.
• Enable Stop processing to prevent later rules from running after a match.
• Use tags to group and filter rules.

Common actions

• Set or remove headers.
• Replace or set the body.
• Redirect to a new URL.
• Add delays or throttling.
• Encode/decode body content.
• Adjust status codes and connection behavior.
