Compose change planning

Know what an update changes before recreating the stack.

Compare two normalized application models, surface the state and access boundaries that move, and leave with one operational update plan.

Compose change impact

Compare the deployed model with the change you intend to make.

Normalize both Compose models, identify structural differences, then convert them into pre-update backup, post-change verification, and rollback actions.

Use rendered Compose output from the same project and environment on both sides. Neither pasted model is added to the URL, saved plan history, copied report metadata, or analytics.

Generic inspection

No deployment blueprint is attached.

The structural analysis still runs, while exposure and recovery remain confirmation items until an intended boundary is attached.

Build and attach a blueprint

Change result

Paste both Compose models to begin.
