OpenReplay is similar to nginx in the sense that the software is available for free for developers and self-hosted, this means data can’t leave a company’s infrastructure, but then extra services are paid for.It’s now raised $4.7M in a Seed funding round led by Runa Capital with the participation of Expa, 468 Capital, Rheinghau Founders, and cofounders of Tekion.OpenReplay provides developers with a session replay stack that helps them troubleshoot issues by making debugging visual, allowing developers to replay everything users do on their web app and potentially understand where and why they got stuck, says the company. Enabling developers to self-host it on their premises and without involving any 3rd-party to handle their user data, is a game changer.”OpenReplay will use the new funding to grow its community, accelerate deployment and improve user experience. OpenReplay is a great example of such an approach.”
