The event invites working tech professionals to form teams of two to four for a 24-hour build with four tracks—Real-Time Analytics, Observability, Data Warehousing, and Agentic AI and Analytics—and a ₹10,00,000 prize pool. Its stated purpose is to bring developers together to build practical systems under tight constraints and experiment with ClickHouse alongside modern open-source tools. The post points to ClickStack for observability, Langfuse for LLM tracing and evaluation, and LibreChat for model and agent interfaces, while describing combinations such as streaming ingestion, materialized views, projections, analytical queries, and tool-using agents over data. Applications close June 25, with shortlists planned for the first week of July; the team captain applies on behalf of the team."

## Summary

ClickHouse announces Click-a-thon 2026, its first in-person hackathon in India, scheduled for Bengaluru on August 1–2, 2026. The event invites working tech professionals to form teams of two to four for a 24-hour build with four tracks—Real-Time Analytics, Observability, Data Warehousing, and Agentic AI and Analytics—and a ₹10,00,000 prize pool. Its stated purpose is to bring developers together to build practical systems under tight constraints and experiment with ClickHouse alongside modern open-source tools. The post points to ClickStack for observability, Langfuse for LLM tracing and evaluation, and LibreChat for model and agent interfaces, while describing combinations such as streaming ingestion, materialized views, projections, analytical queries, and tool-using agents over data. Applications close June 25, with shortlists planned for the first week of July; the team captain applies on behalf of the team.

## Context

ClickHouse presents the hackathon as a way to spend more time with developers and explore the builder culture around its analytical database. The 24-hour constraint is intended to encourage practical decisions, smaller working versions, and experimentation by small teams combining ClickHouse with other modern open-source tools.

## Approach / What changed

The event uses four technical tracks and asks teams of two to four working tech professionals to build for 24 hours in Bengaluru. Suggested components include ClickStack for observability, Langfuse for LLM tracing and evaluation, and LibreChat for model and agent interfaces. The post also identifies streaming ingestion, materialized views, projections, schema design, query optimization, and tool-using agents as possible implementation areas.

## Takeaways

- Click-a-thon 2026 will take place in Bengaluru on August 1–2, with a 24-hour format, four tracks, and a total prize pool of ₹10,00,000.
- ClickStack combines HyperDX, OpenTelemetry, and ClickHouse for logs, metrics, traces, and session replays, with the post describing sub-second queries over terabytes.
- Applications close June 25, shortlists are scheduled for the first week of July, and the team captain applies on behalf of a team of two to four people.
