# Compare two tool versions

> Free public version-diff tool for any Relnx-tracked tool. No login required.

The [version compare page](https://www.relnx.io/compare) is a free public tool
that diffs the changes between any two versions of a Relnx-tracked tool — a
gap report you can read before an upgrade.

## Use it

1. Visit [www.relnx.io/compare](https://www.relnx.io/compare).
2. Pick a tool.
3. Pick **From** and **To** versions.
4. Hit **Compare**.

You'll get:

* A consolidated list of features added between the two versions.
* Counts of breaking changes and security fixes.
* AI summaries on each feature card.
* Direct links to upstream PRs and release pages.

No account is required.

## Use cases

* **Pre-upgrade gap report**: "We're on ArgoCD 2.10.0, considering 2.13.x.
  What lands in between?"
* **Audit a long stretch**: "What changed in Kubernetes 1.27 → 1.30?"
* **Justify staying back**: see if the diff is mostly chores vs. real value.

## Limits

* Both versions must already be in Relnx — the most recently released
  versions show up within a sync cycle (\~12 hours of upstream).
* Pre-releases and dev tags (e.g. `2.x-dev.6`) are included if Relnx tracked
  them, but the comparison is most useful between stable versions.

## Tips

* Use the URL after picking versions — it's permalinkable, so you can paste
  it into an upgrade ticket or RFC.
* The page is fully cached at the edge; loading is fast even for large
  diffs.
