GoReplay is an open-source tool for capturing and replaying live HTTP traffic into a test environment in order to continuously test your system with real data. It can be used to increase confidence in code deployments, configuration changes and infrastructure changes.
GoReplay is an open-source network monitoring tool which can record your live traffic, and use it for shadowing, load testing, monitoring and detailed analysis.
As your application grows, the effort required to test it also grows exponentially. GoReplay offers you the simple idea of reusing your existing traffic for testing, which makes it incredibly powerful. Our state of art technique allows you to analyze and record your application traffic without affecting it. This eliminates the risks that come with putting a third party component in the critical path.
GoReplay increases your confidence in code deployments, configuration and infrastructure changes.
GoReplay offers unique approach for shadowing. Instead of being a proxy, GoReplay in background listen for traffic on your network interface, requiring no changes in your production infrastructure, rather then running GoReplay daemon on the same machine as your service.
Check latest documentation.
Download latest binary from https://github.com/buger/goreplay/releases or compile by yourself.
The most basic setup will be
sudo ./gor --input-raw :8000 --output-stdoutwhich acts like tcpdump. If you already have test environment you can start replaying:
sudo ./gor --input-raw :8000 --output-http http://staging.env.
