What the current evidence supports

Human editorial judgment · 2026-08-20

Adopt with guardrails

Why
3.0 is a live W3C-track standard already shipping in all major browsers with GC (Chrome 119+, Firefox 120+, Safari 18.2+, ~85% global), exceptions, and SIMD baseline-available; core risk is feature-detection across the browser/engine matrix, not maturity
Next
Pilot a WasmGC-compiled module (e.g. a Kotlin/Java compute kernel) in one browser-side workload; verify GC + exception-handling support on the actual target browser matrix before relying on it
