What Highlight does
Highlight (operating as highlight.io; legal entity Highlight Inc.) is an open-source, full-stack monitoring platform for web applications, founded in 2020 and headquartered in San Francisco, California. The platform unifies five product modules — Session Replay, Error Monitoring, Logging, Tracing, and Dashboards & APM — into a single pane built on ClickHouse for time-series storage and OpenTelemetry for distributed tracing. It offers SDKs across client-side JavaScript and server-side languages (Go, Node.js, Python, Ruby, Rust, Java, Hono, Next.js) plus an 18+ integration ecosystem spanning cloud infrastructure, BI/analytics, ITSM, and communication tools, with optional self-hosting via Docker for data-sovereignty use cases.
The company's business model is a PLG-led freemium SaaS with tiered pricing (Free, Pay-as-you-go at $50/month, Business at $800/month, and Enterprise via custom contract), supplemented by self-hosted Enterprise licensing for large organizations. Its primary customer segment is software developers and engineering teams that need coherent visibility from frontend session replay to backend logs and traces; a secondary segment is technical customer success teams. Compliance posture includes SOC 2 Type 2 certification, GDPR compliance, and HIPAA certification in progress, supporting engagement with regulated enterprise customers such as Blue Cross of Idaho alongside numerous startup logos (Pipe, Portal, Dripos, Knock, Hightouch, Basedash, Mage, Airplane, Secoda, Whop, Aurora).
Following a November 2023 acquisition by LaunchDarkly (total disclosed funding of approximately $8.5M across an April 2023 Y Combinator seed and an August 2023 $8M Series A led by Afore Capital and Craft Ventures), Highlight is operating in a wind-down phase. All Highlight.io features have been moved into LaunchDarkly Observability, and legacy Highlight.io services are scheduled for deprecation on February 28, 2026, with customers required to update SDK snippets by March 1, 2026. The team (1–10 employees) is led by Co-founder & CEO Jay Khatri and Co-founder & CTO Vadim Korolik.
