ClickSight.
From events to an explanation.
A ClickHouse-native analytics interface developed as professional open-source work at Allen.
CLICKSIGHT / SIGNAL FROM EVENTS
Ask a better question.
Follow the events.
What it makes possible.
Give teams a usable interface for exploring product events directly in ClickHouse.
- Event trends, funnels, retention, cohorts and user paths.
- Dashboards, a SQL editor and an AI-assisted exploration interface.
- A React interface querying ClickHouse without a standalone application backend.
Under the surface.
- 01
React, Ant Design and Recharts render the analytics workspace.
- 02
Queries run against ClickHouse; the SQL editor uses Monaco.
- 03
Sankey diagrams explain paths through event sequences.
The deliberate choices.
- Work directly with the event warehouse rather than adding another analytics data copy.
- Offer both guided analysis and SQL for different levels of investigation.
- Keep attribution clear: this is professional open-source work, not a standalone personal product.
Where it stands.
The open-source interface is part of Allen’s analytics work. The wider in-house platform serves 200M events per day and saved $350K per year; those résumé outcomes belong to the platform, not to the UI alone.
