OpenReplay raises $4.7M for its open source tool to find the bugs in sites

When users on websites and apps find they have problems, developers have various tools to record what they are doing in order to find out what went wrong. But these can involve cumbersome methods like screenshots, and back-and-forth emails with customers.
ContentSquare and Medallia are products that primarily target marketers and product managers rather than developers, who need to know where apps are going wrong. Meanwhile, developers are using open source solutions, but these have their drawbacks.
OpenReplay is similar to nginx in the sense that the software is available for free for develop
