At QuestDB we are excited to welcome new and returning contributors to our projects and to celebrate another year of collaboration.

QuestDB + Hacktoberfest 2025: Build Something That Lasts

What is Hacktoberfest?

Hacktoberfest is an annual celebration of open source organized by DigitalOcean. From October 1 through October 31, anyone can take part by opening pull requests and helping projects grow. It is a great chance to sharpen your skills and connect with the global developer community.

Why contribute to QuestDB?

QuestDB is an open source time-series database focused on performance and simplicity. The core engine is built in Java, C++, and Rust. Alongside it we maintain a web console written in TypeScript and React, and a full set of documentation. All of these are open for contributions, and Hacktoberfest is the perfect time to get involved.

We value quality over quantity. Small typo fixes are always appreciated, but for Hacktoberfest we encourage contributors to look for issues that have a real impact. You will find open issues with the hacktoberfest label in our GitHub repos. If you are unsure where to begin, drop a message in the #contributors channel of our Slack and we will point you in the right direction. AI-generated contributions are discouraged because we want your ideas and your work.

Rewards

Contributing to open source is rewarding in itself, but we like to add a little extra. Anyone who successfully contributes to a QuestDB project during Hacktoberfest will receive one of our exclusive t-shirts as a thank you. And that's on top of the Hacktoberfest Rewards.
