Technical Specifications & System Requirements
Software notes
Features
- Records all HTTP and HTTPS traffic between your device and the internet in one readable session view, ending the guesswork about what an app actually sent, received, or silently failed on.
- SSL proxying with a guided root-certificate setup decrypts HTTPS for the hosts you choose, which makes debugging secure mobile and desktop app traffic practical rather than painful.
- Bandwidth throttling presets simulate 3G, 4G, and custom slow or lossy connections, exposing timeout, retry, and loading-state bugs that never appear on a fast office network.
- Breakpoints let you pause a live request or response and edit headers or body contents before it continues, which is invaluable for testing how an app handles server errors.
- Captures traffic from iPhones, Android devices, emulators, and desktop apps on the same Wi-Fi network, and sessions can be saved and shared with teammates for later analysis.
Considerations
- The unlicensed trial stops recording after 30 minutes per session and adds launch delays, so any serious daily use effectively requires buying a licence.
- Decrypting HTTPS requires installing the Charles root certificate plus per-host SSL settings, a setup step that can confuse first-time users and clash with strict corporate IT policies.
- Free alternatives such as mitmproxy and the browser developer tools cover basic traffic inspection, so casual users may not get enough extra value to justify the price.

Frequently Asked Questions & Verification Guide
Is Charles Proxy free?
Charles is commercial software with a free trial: the unlicensed version limits recording sessions to 30 minutes and adds startup delays. A single-user licence removes those limits.
Can Charles inspect HTTPS traffic?
Yes. Install the Charles root certificate on your device, enable SSL proxying for the hosts you want to inspect, and Charles shows the decrypted request and response bodies for those hosts.
Can I debug my phone's app traffic with Charles?
Yes. Connect the phone to the same Wi-Fi network, point its proxy settings at your computer running Charles, install the certificate from chls.pro/ssl, and the app's traffic appears in your session.
What is the difference between Charles and Fiddler?
Both are web debugging proxies. Charles is fully cross-platform with a native interface on Windows, macOS, and Linux, while classic Fiddler is Windows-only; Charles is paid software with a time-limited trial.
Does Charles work with Android emulators and the iOS Simulator?
Yes. Both can be configured to route their traffic through Charles, and the official documentation walks through the proxy and certificate setup for each platform.
