Sealed, self-contained deployments

When you publish a funnel, it becomes a sealed snapshot: the exact code, assets, and config from that moment, frozen together. Nothing you ship to the platform later can change how a live funnel behaves. What you tested is what your visitors get, indefinitely.

Use cases

  • Ship without fear - a platform upgrade can never silently alter a funnel you already published
  • Reproduce any release - every deployment is a self-contained artifact you can inspect and roll back to
  • Long-running campaigns - a funnel launched months ago renders exactly as it did on day one

Impact

Your live funnels stop drifting. Once a release passes your review it is locked, so the version making you money keeps behaving identically no matter what changes underneath. That makes releases predictable and rollbacks trivial.
