$ agent build --scene aurora-hero.ts && vibegl verify

Your agent writes the scene.
VibeGL proves it ships.

Vibe-coded 3D demos are easy now. Production graphics are not. Untested shader cost, no device tiers, no WebGPU fallback, no rollback story. VibeGL is the control plane between "the agent made something gorgeous" and "it runs on your users' phones."

For humans

Prompt or reference in; tested, responsive and accessible web component out.

For agents

Machine-first API: submit a bundle, receive JSON verdicts, PNG evidence, tiers, fallbacks and a versioned artifact. Start at /llms.txt.

The problem, in one run

Demos lie. Evidence doesn't.

$ vibegl verify ./aurora-hero
# browser matrix · visual contracts · GPU evidence
✓ visual contract "hero-default-view"      Δ 0.4% (pass ≤ 1.5%)
✓ WebGPU → WebGL2 fallback                 renders, Δ 2.1% (allowed 4%)
▲ frame budget @ mobile-tier               11.2ms avg, 19.8ms p95 (p95 over 16.6ms)
✓ context-loss recovery                    restored in 240ms
✓ reduced-motion variant                   static poster served
▲ memory: +38MB after 5min loop            suspect: unpooled geometries (report §4)
verdict: SHIP WITH TIER CAP — mobile gets tier-2 (half-res bloom off)

Control plane

Seven stages between prompt and production.

Generation and inspection tools exist. Nobody owns the part where graphics code becomes deployable. That's the whole product.
