How to find us

What happens when we use what's best for a change?

Are you interested in technologies beyond the mainstream that are a pleasure to use and effective at getting the job done?

BOB is the forum for developers, architects and builders to explore and discover the best tools available today for building software. Our goal is for all participants to leave the conference with new ideas to improve development back at the ranch.

We are committed to diversity: We aim at exploring a wide range of tools in a welcoming and friendly crowd of diverse people. To that end, a number of support options for participants from groups under-represented in tech are available.

BOB 2023 and COVID

We expect we'll be able to hold BOB 2023 on site in Berlin.

Note that we intend to provide a safe environment for all participants. There will be space outside to eat and chat. We may ask you to wear a mask indoors when not presenting or eating, and may also ask you to take a COVID test on-site before the event.

If an on-site BOB is not possible, we'll make BOB a successful online event, like BOB 2021 and BOB 2022. Watch this space – we'll keep you updated.
