Reliability: repo‑centric Copilot/code actions (CI scripts) are versioned, testable and reproducible—better for deterministic deployments. Zapier has broader integrations but can hit rate limits, UI changes, and intermittent task failures.

Observability: CI systems + structured logs and Git history give richer tracing/alerts. Zapier provides task history and basic logs but limited metrics for on‑call.

Rollback: prefer code paths—revert commits, tags, blue/green or feature flags. For Zapier build idempotent/compensating actions and an external state store.
