Hello,

Every tap, every query, every agent call is racing some database to respond before the user notices the wait. ClickHouse is the one that usually wins that race, and we're bringing it to Bengaluru for 24 hours to see what you'll build on it.

24 hours | Bengaluru | August 1-2, 2026.

Launching Click-a-thon 2026, ClickHouse's first in-person hackathon in India, and we're inviting working tech professionals to come build something remarkable.

Pick a problem from the list of problem statements that matter to you — to be revealed on the event day. Build a solution that works. Leave with bragging rights, and a prize pool worth ₹10,00,000.

Four tracks to build on

• Real-time Analytics & Dashboards: make data move and respond at speed
• Observability & Log Analytics: finally, logs and traces that make sense
• Data Warehousing: large-scale data, fast answers
• Agentic AI + Analytics: AI that doesn't just talk, it queries

Explore the open source stack you'll be working with alongside ClickHouse. Teams must meaningfully integrate at least one; bonus points if you use all three:

• ClickStack: Open source observability stack powered by ClickHouse.
• Langfuse: Open source LLM observability and analytics.
• LibreChat: Open source AI chat platform.

Key dates

• Applications close: June 25, 2026
• Shortlist announced: First week of July
• Hack weekend: August 1–2, 2026, Bengaluru

Teams of 2–4. One person applies on behalf of the team.
