What is the difference between Comment History for Jira and Comment History Log for Jira?

Both apps fill the same gap in Jira: native Jira does not retain comment edits or deletions. They differ in the way history is presented. Comment History for Jira shows every prior version of a comment in a hierarchical, expandable list under the comment itself, with full text for each version. Comment History Log emphasises a visual delta-diff view, highlighting what changed between versions. Pick the one whose surface matches how your auditors and team members read history.

Which app should I pick for SOX, GxP, or ISO 27001 audits?

Either app gives you what native Jira lacks — a durable record of comment edits and deletes. For audits, the things to verify are: (a) the record is immutable, (b) it captures author and timestamp for every change, (c) it can be exported, and (d) admin actions on the history are themselves audited. Both apps cover (a)-(c). Confirm export and admin-action audit with each vendor before committing.

Can I install both apps side-by-side?

Technically yes — they don't share data and won't conflict. Practically, no — you'd be paying twice for overlapping functionality. Pick one based on the trial. Most Atlassian admins make this decision in under a week of evaluation.

Is Comment History for Jira available on Data Center?

Yes. Comment History for Jira ships both a Cloud edition and a Data Center edition. Comment History Log is also available on both platforms. Always check the live Marketplace listing for the current supported version range.

Comment History for Jira vs Comment History Log — Which Comment Audit App Should You Pick?

This comparison is for teams who have already concluded that native Jira’s lack of comment-edit history is unacceptable and are picking between Comment History for Jira by Redmoon Software and Comment History Log for Jira. Both apps appear on most Atlassian admin shortlists for this category. They solve the same problem with slightly different surfaces.

The 30-second answer

Comment History for Jira presents every prior version of a comment as a full, expandable record nested under the comment in the Jira UI. You can read the whole text of any old version, see who edited it and when, and view deleted comments that would otherwise be gone forever.

Comment History Log emphasises a visual delta-diff view between versions — strike-through for removed text, highlight for added text. Some teams prefer this for spotting what changed; others find the full-version view clearer.

If your auditors care about “what did this comment originally say” — full-version is easier. If your teams care about “what did the last edit change” — delta-diff is easier. Neither is universally better; pick the surface that matches how your readers actually read.

When Comment History for Jira is the right pick

Auditors read full comment text. SOX, GxP, ISO 27001 reviewers typically want to see the entire prior version of a comment, not just the diff. Comment History for Jira gives them that view by default.
You want history visible in-line on the issue. Comment History for Jira nests prior versions directly beneath the comment they belong to. No new tab, no separate report.
You’re on the Redmoon stack already. If you already use Comment Security Default Data Center/Cloud or Document Vault [Data Center]](/document-vault-overview/)/[Cloud]](/document-vault-overview-cloud/), staying with one vendor simplifies licensing, support, and renewal cycles.
You need Data Center. Comment History for Jira has a mature Data Center edition with the same hierarchical history view as Cloud.

When Comment History Log is the right pick

Your team thinks in diffs. Engineering teams who already read pull-request diffs daily often find the delta-diff format more natural than reading two full versions side-by-side.
Comments tend to be long. When a comment is multiple paragraphs and only one sentence changed, a delta-diff highlights the change immediately. Full-version side-by-side requires reading both.
You’re already a Comment History Log customer. Migrating between audit apps is usually not worth the disruption unless one tool is missing a feature you need.

Be honest: for most teams, this comes down to UX preference, not feature checklists. Run a one-day trial of each on the same project and ask three of your team’s heaviest comment authors which they’d rather read.

What they both fix

Native Jira deletes the prior content of a comment when a user edits it. Native Jira deletes the comment outright on delete. There is no recovery. This is a well-known gap that has been on the Jira backlog for over a decade and is unlikely to be fixed natively.

Both Comment History for Jira and Comment History Log fix this gap. Either app, installed on day one, will retain edits and deletions from that point forward.

Neither app retrospectively reconstructs comment history from before installation — that data is gone. Install ASAP if your compliance posture requires it.

Cost considerations

Both apps are priced on the Atlassian Marketplace, tiered by Jira user count. Pricing is best read from the live Marketplace listings:

Both apps are inexpensive relative to the cost of an audit finding caused by missing comment history. For most teams the differentiator is fit and support quality, not price.
