Built with Opus 4.7: a Claude Code hackathon

Join us again for Built with Opus 4.7: a Claude Code virtual hackathon!

Opus 4.7 is our most capable model yet, and we’re excited for you to push the limits of what it can do. Whether you’re a seasoned engineer or newly a builder, show us what you can build in one week with Claude Code.

Some projects will start from what you already know — show us the thing only you'd know to build, the problem in your work or community that takes weeks but should take hours. Others will start from what's next — show us something that's easier to demo than to explain, an idea that doesn't exist yet but should.

We’ll select 500 participants and give each one $500 in Claude API credits to build for a week. Compete to win $100k in Claude API credits. 

Judges include Boris Cherny, Cat Wu, Thariq Shihipar, Lydia Hallie, Ado Kukic, and Jason Bigman from the Claude team.

Note: This event is fully virtual. Space is limited to 500 participants. Maximum team size is two. All participants must submit an application for approval.
