Console Delta – Play Mode Log Comparison

See what changed since your last Play Mode run.

You make a change, press Play, and Unity fills the Console with logs, warnings, and errors.

But what actually changed?

Which problems appeared after your last change? Which warnings became errors? Which issues disappeared? And which messages are simply the same noise you have already seen?

Console Delta makes those differences visible automatically.

Console Delta is a Unity Editor diagnostic tool that captures Play Mode sessions, identifies recurring diagnostic issues, and compares them between runs.

Instead of clearing the Console and trying to remember what happened last time, you get a clear before-and-after view of your project's diagnostics.

KNOW WHAT CHANGED:

Console Delta organizes diagnostics into four meaningful comparison statuses:

• NEW: Issues that appear in the current run but were absent from the selected comparison run.
• REGRESSED: Existing issues that became more severe, such as a Warning turning into an Error.
• RESOLVED: Previously observed issues that no longer appear in the current run.
• UNCHANGED: Issues that remain at the same severity, helping you separate familiar noise from meaningful changes.

You can also identify REAPPEARED issues - problems that return after being absent from a previous complete run.

This means you can focus on the consequences of your latest changes instead of repeatedly investigating the same messages.

INVESTIGATE ISSUES, NOT JUST LOG LINES:

Finding a changed issue is only the beginning.

Console Delta gives you the context needed to understand what happened and where to investigate.

• Issue Timeline: Follow individual issues across retained Play Mode runs and see when they appeared, disappeared, changed severity, or returned.
• Raw Events: Inspect the original captured messages, timestamps, and stack traces behind grouped issues.
• Source Navigation: Open resolvable source locations directly from diagnostic details.
• Run History: Review previous sessions and select which runs to compare.
• Known Issues: Mark familiar problems as Known and reduce unchanged noise without deleting the underlying diagnostic information.
• Search and Filtering: Narrow down issues by text, status, severity, and available filters.
• Diagnostic Export: Copy diagnostic context or export information as Markdown or JSON.

A BETTER WORKFLOW FOR EVERY PLAY MODE TEST:

Console Delta works alongside Unity's built-in Console. You do not need to replace your existing logging calls or install a separate logging framework.

1. Enter Play Mode and test your project.
2. Stop Play Mode.
3. Make a code or project change.
4. Enter Play Mode again.
5. Open **Window → Console Delta**.
6. See what changed and investigate the issues that matter.

Your diagnostic history remains available between Editor sessions, so you can return to previous results when needed.

BUILT FOR TRUSTWORTHY RESULTS:

Console Delta takes a conservative approach to diagnostic comparison.

• Matches issues using message and call-site information rather than aggressively guessing that different messages are identical.
• Preserves captured raw diagnostic information for inspection.
• Distinguishes severity regressions from simple occurrence-count changes.
• Reports uncertainty when incomplete or degraded runs cannot prove that an issue was absent.
• Keeps Known issues visible when they become more severe.

INCLUDED WITH CONSOLE DELTA:

• Complete Unity Editor diagnostic extension
• Automatic Play Mode diagnostic capture
• NEW, REGRESSED, RESOLVED, and UNCHANGED comparisons
• Issue timelines and REAPPEARED detection
• Raw Events inspection
• Run history and baseline selection
• Known issue management
• Search, filtering, and source navigation
• Clipboard, Markdown, and JSON export
• Optional three-scenario demonstration sample
• Documentation and troubleshooting guidance

DESIGNED TO STAY OUT OF YOUR WAY:

Console Delta is Editor-only, stores diagnostic history locally, and does not require accounts, telemetry, cloud services, or subscriptions.

It is designed to work with your normal Unity development process, not replace it.

Less time comparing logs. More time understanding what your changes actually did.
