What is Highlight.io?
Highlight.io was an open-source, full-stack monitoring platform combining session replay, error monitoring, logging and tracing. As of 27 September 2026, highlight.io, www.highlight.io and highlight.run all redirect (HTTP 301/308) to launchdarkly.com, consistent with the product being absorbed into LaunchDarkly. The GitHub repository is still active and still describes itself as an open-source monitoring platform, but the dedicated docs and marketing pages no longer resolve to Highlight-specific content.

Highlight.ioMonitoring & ObservabilityOpen-source monitoring project now folded into LaunchDarkly
Key capabilities
- Open-source repository: the highlight/highlight GitHub project remains active with session replay, error monitoring, logging and tracing code.
- No live marketing site: highlight.io and highlight.run redirect to LaunchDarkly rather than showing Highlight-specific product or pricing pages.
- Self-hosting: the open-source edition can still be self-hosted from source per the repository's instructions.
A vendor's own domain permanently redirecting to a different company's homepage is a strong, checkable signal of an acquisition or wind-down. This profile reflects that instead of repeating outdated positioning.
