  "what": "An open-source full-stack monitoring app combining session replay, error monitoring, logging and OpenTelemetry tracing in one self-hostable Docker stack. LaunchDarkly acquired it and folded the features into LaunchDarkly Observability. The GitHub repo remains public and actively committed to, but the hosted app.highlight.io service has shut down.",
  "why": "It is now purely a self-host play: if you want replay plus errors plus traces on your own hardware with no per-event bill, this is one of very few Apache-2.0 options.",
  "warn": "Do not plan around the cloud product. It ended on <b>28 February 2026</b> and SDK snippets had to be repointed at LaunchDarkly before 1 March 2026. Self-hosting means operating ClickHouse, Kafka and Postgres yourself.",
