Overview

Highlight.io is an open-source, full-stack application monitoring platform founded in 2020 and backed by Y Combinator (W23). It combines session replay, error monitoring, logging, and distributed tracing into a single cohesive interface, enabling engineering teams to understand both the 'what' and 'why' behind application issues without manually correlating data across disparate tools. Built on OpenTelemetry and powered by ClickHouse, it supports modern full-stack frameworks including Next.js, React, and Remix, with SDKs across JavaScript, Go, Python, Java, and Ruby. A self-hosting path via Docker or Kubernetes caters to privacy-sensitive deployments. Highlight raised $8.5M in seed funding before being acquired by LaunchDarkly in April 2025, where it is being integrated as the observability layer for LaunchDarkly's Guarded Releases feature flag platform.
