THorn HTTP: Intercept & Modify HTTP Requests bởi Cleber Silva

THorn HTTP lets you intercept and modify HTTP(S) traffic right in your browser. Everything runs locally: no account, no cloud, no analytics.

Rules
• Redirect Request: send a URL (or a pattern) to another URL, e.g. production → localhost
• Replace String: replace parts of URLs or hosts
• Query Param: add, change or remove query parameters
• Modify Headers: add, change or remove request and response headers
• Modify API Response: mock REST and GraphQL responses
• Modify Request Body: override request payloads
• Insert Scripts: inject JavaScript or CSS into pages
• Cancel Request: block requests
• Delay Network Requests: simulate slow APIs
• User-Agent: emulate other devices and browsers

Also
• Record the network traffic of a page and export it as HAR
• DevTools panel showing which rules ran on each request
• Import and export rules as JSON (Requestly exports are supported)
• Import from Charles Proxy, ModHeader, Resource Override and Header Editor
• Pause everything with one switch

Privacy
THorn HTTP stores your rules only in your browser and sends no data anywhere.
