Decision

What the current evidence supports

Human editorial judgment · 2026-06-28

Proceed with caution

Why
~95-98% npm compat and strong startup/install speed make it attractive, but named compat gaps (native addons, node:cluster, missing node modules), absent APM guidance, and benchmark realism (<3% real-workload delta) argue against migrating existing Node production services wholesale.
Next
Adopt Bun first in CI (test/install speed) and for a narrowly-scoped new microservice with no native addons; run a 72h+ soak test and verify Sentry/OTel coverage and native-module support (bcrypt/sharp) before any production-facing service.
