The BrowserUp MITM Proxy allows you to capture HTTP requests, and responses and content, and export performance data as a HAR file.
The BrowserUp MITM Proxy is a fork of the amazing mitmproxy, with an added performance testing, QA and DevOps flavor.
Along with the standard mitmproxy features, the BrowserUp MITM Proxy offers adds a REST control API and native language clients in Java, JavaScript, Python and Ruby. It allows HAR capture (websockets and HTTP/2 too), and provides the ability to verify (assert) about network traffic.
BrowserUp MITM Proxy is especially useful when used with Selenium or Cypress tests.
The REST API is documented here
Getting started:
Clone our fork:
git clone https://github.com/browserup/mitmproxy.git
Follow the mitmproxy certificate setup instructions
Run one of our examples in clients/examples
The standard mitmproxy executables are also shipped, and should work as normal.
BrowserUp is a code contributor to the upstream project, and we hope to continue to support them with code contributions where possible.
Our fork for HAR, and clients are in the browserup addons.s
