Helm Values Diff

Helm Values Diff

Paste your values.yaml for each environment to see added, removed, and changed keys side-by-side. Pure deep-diff, no chart rendering required.

What This Tool Does

Helm Values Diff is built for deterministic developer and agent workflows.

Diff Helm values.yaml across dev, staging, and prod. See added, removed, and changed keys, override sources, and merged effective values per environment. Pure YAML deep-diff in your browser.

Use How to Use for execution steps and FAQ for constraints, policies, and edge cases.

How to Use Helm Values Diff

  1. 1

    Paste each environment

    Drop your dev, staging, and prod values.yaml files into the three editor panes. Each is parsed independently and any YAML errors surface inline so you can fix typos before diffing.

  2. 2

    Read the status badges

    Each key shows match (same in all envs), partial (some envs differ), all differ (every env unique), or missing (key only exists in some envs). Filter the table to focus on what matters.

  3. 3

    Trace override sources

    The Override Source column shows which environments declare a key. A key marked dev + prod but missing in staging is exactly the kind of drift that breaks deploys.

  4. 4

    Inspect merged effective values

    The bottom pane shows the parsed JSON tree per environment so you can spot deeply nested differences the flat diff misses, like a single field changed inside a large block.

  5. 5

    Sync your environments

    Use the diff to drive a values cleanup PR: add missing keys, normalize accidental drift, and document intentional differences in chart README so future you knows what is on purpose.

Frequently Asked Questions

What is Helm Values Diff?
It compares Helm values.yaml files for dev, staging, and prod environments and reports added, removed, and changed keys with their values side by side. Helps catch configuration drift between environments.
How does the diff handle nested keys?
All values are flattened to dotted paths (image.tag, resources.limits.cpu) before comparing. This means a deeply nested change is as visible as a top-level key change, with no hierarchy noise.
What does the Override Source column mean?
It lists which environments declare the key. A key declared only in prod is a prod-only override. A key declared in dev and staging but missing in prod often indicates a forgotten promotion.
Does it send my data to a server?
No. Parsing and diffing happen in your browser. Your values files, including any embedded secrets or registry paths, never leave your device.
Can I diff more than three environments?
The current build supports dev, staging, and prod side by side. For ad-hoc diffs of two arbitrary files, leave the third pane empty and ignore the missing markers in that column.
