Click-a-thon 2026: Build with the fastest database on the planet

🚀 ClickHouse's first in-person developer hackathon in India is here.
Join ~120 professional developers across ~30 teams for 24 hours of focused, high-intensity engineering — building real-world solutions on ClickHouse and the open-source analytics stack.
If you've ever wanted to push the limits of real-time analytics, ship something ambitious with a small team, and get your work in front of the wider data community, this is the room to be in.

Problem statements within each track come from our partner companies — real challenges from real engineering teams.
