Reuse builds across multiple services
Summary
Render now lets you reuse a single build artifact across multiple services, cutting duplicate builds and ensuring identical code moves from staging to production. The feature is in private beta, works for web, private, and worker services, and separates build‑time from runtime secrets.
- Define a single Build Source (repo, branch, command) and link multiple Render services to reuse the same immutable artifact.
- Promoting the same build across dev, staging, and prod eliminates drift caused by differing build‑time variables.
- Build‑time and runtime variables are scoped separately, so secrets aren't exposed during the build unless explicitly passed.
- Supported for web services, private services, and background workers; managed via REST API, Blueprints, and the Dashboard.
Teams running multiple services on Render will save build time and reduce environment drift by sharing a single immutable build.
