Every's Vibe Coding Marathon was an 8-hour livestream where the world's best vibe coders built live using Claude Code, Opus 4.5, Figma, and Notion. Over 30,000 viewers tuned in, establishing the livestream hackathon as a viable media format.
What it was
Every (the publication / community) ran an 8-hour livestream hackathon in September 2025 under the banner "Vibe Coding Marathon" (also called Vibe Code Camp). The format: a curated set of high-profile vibe coders built live, on-camera, using Claude Code with Opus 4.5, alongside Figma for design and Notion for spec/doc work.
Over 30,000 viewers watched live: a number that put the event in the same viewership tier as a mid-sized esports tournament and established the livestream-hackathon as a viable media format.
Why it mattered
- Hackathon as content. Pre-Every, hackathons were mostly participatory events (you join or you don't). Every's marathon treated hackathons as broadcast content, viewers who didn't build could still follow along, learn from how top builders work, and share clips. That's a different distribution surface entirely.
- Brand-curated talent. By choosing who builds on-camera, Every controlled the quality bar. Audiences got watchable, instructive builds rather than the variance of an open-submission hackathon.
- Tool stack on display. Claude Code + Opus 4.5 + Figma + Notion was a deliberate stack choice. The 30K+ viewers got an 8-hour live demonstration of how that stack actually composes, better marketing than any product demo.
