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.
