    Hey HN! We’re open-sourcing highlight.io (https://github.com/highlight/highlight), a session replay and error monitoring tool. Highlight.io gives you a high-precision video-like replay of what users are doing when an error or exception occurs in your web app, along with a full-fledged error monitoring experience (similar to bugsnag, rollbar, etc..).

    Hey HN. We’re Jay and Vadim from Highlight.io (https://highlight.io). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had…

    Hey HN, I’m Jay, a co-founder at Highlight and a YC alum; excited to share our replay-based debugging tool! TLDR; if you're using a tool like Fullstory for debugging, or you have trouble understanding the actual impact of your errors (e.g. in sentry), you should give us a try! We built Highlight because we constantly found ourselves flooded with errors and support tickets with very little context on why these issues occurred. To make matters worse, there was never an easy (and less annoying way) of reproducing these errors, other than by asking users to send screenshots, videos, etc.…
