How to build once and deploy many times
The same artefact is rebuilt for every environment.

The same artefact is rebuilt for every environment.
Why it happens
Each deploy pipeline builds from source rather than promoting a tested artefact.
How to fix it
- Build once, tag by content hash, and promote the same digest through environments
- Never rebuild between staging and production — it invalidates your testing
- Store the artefact in a registry and reference it by digest
Your next build could be twice as fast, at half the price
Start free. Migrating away is the same one line, and we publish that diff too.
