App compatibility scanner (open beta): check Jira and Confluence DC apps before upgrading

[#1]

Hi everyone,

Based on your inputs on this post:
Help us improve the App compatibility checker – We need your feedback!

We’re opening up the App compatibility scanner in an open beta starting April 20 to help Jira and Confluence Data Center admins check their apps before upgrading.

This post shares what the tool is, who it’s for, key benefits, how to get started, and how to give feedback.

What is the App compatibility scanner?

The App compatibility scanner is a tool designed to help Jira and Confluence admins quickly check whether their installed apps, especially custom (in‑house) apps, are compatible with upcoming Data Center versions and understand the details of any incompatibilities.

Note: This is still work in progress and focused on a specific set of versions and checks. It’s already useful today, but it might not cover 100% of use cases yet as we continue to expand coverage based on your feedback.

Who is this for?

This open beta is intended for:

• Jira and Confluence Data Center admins

• Customers with custom (in‑house) apps

• Teams planning upgrades along the supported LTS versions

• Customers who can safely test new tools in a non‑production / test environment

What you can do with it today (key benefits)

With the current open beta, you can:

• See an overview of app compatibility status for your instance

• Identify incompatible Java APIs used by your custom apps against specific target versions

• Highlight major dependency updates in custom (in‑house) apps

• Export scan results in CSV or JSON format to share with developers and architects

Under the hood, the tool currently includes:

• Marketplace Compatibility Matrix
  Checks app compatibility (yes or no) based on vendor‑provided information (Marketplace apps)

• Java API usage check
  Flags incompatible Java APIs in your target versions:

  • Jira: 9.12, 10.3, 11.3

  • Confluence: 8.5, 9.2, 10.2
    (applies to custom (in‑house) apps)

• Dependency check
  Highlights major dependency updates for custom (in‑house) apps
