## What it is
Tamper Dev is a browser extension that intercepts and edits HTTP/HTTPS requests and responses in real time without requiring a proxy or auxiliary app. It is the successor to Tamper Chrome and supports multiple browsers with full HTTPS support.

## Use cases
- debug http requests from my browser
- intercept and modify https requests without a proxy
- test web app security vulnerabilities
- inspect and edit request headers and body
- mock server responses in the browser
- alternative to burp suite for browser traffic

## When to choose
- you need to intercept or modify browser HTTP/HTTPS traffic with zero setup
- you want a lightweight Burp Proxy / MITM Proxy alternative inside the browser
- you are a pentester or developer debugging web requests on any OS including Chrome OS

## When to avoid
- you need to intercept traffic from non-browser applications
- you require advanced automated scanning or full proxy-based pentesting features
- you need to capture traffic at the network level outside the browser
