highlight.io is an open source monitoring platform that provides developers with comprehensive visibility into their web applications.
Highlight (highlight.io) is an open source monitoring platform built for developers who need visibility into how their web applications are performing and where they are failing. It centers on giving engineering teams a clearer picture of what is happening inside a running application, rather than relying on guesswork after users report problems. Who uses Highlight Highlight is aimed at developers and engineering teams responsible for building and maintaining web applications. It fits teams that want monitoring built into their own stack, with the option to inspect and extend the platform since it is open source rather than a closed, black-box service. Because it is open source, teams can review how the monitoring works, adapt it to their own infrastructure, and avoid being locked into a proprietary vendor for a core part of their observability setup. For a maker or small engineering team, adopting Highlight means adding a monitoring layer that is transparent about how it works under the hood, which can matter when debugging production issues or deciding how much visibility to build versus buy.
