Two agents. One ticket. Caught.
See who else is on a Jira issue right now, get warned before two agents reply to the same ticket, and know the moment someone changes an issue you have open.
Free for up to 10 users · Jira Cloud, Jira Service Management · Runs on Atlassian
A Jira and Jira Service Management app that shows who is on every issue in real time, warns at the top of the page when a teammate opens the same ticket, tells you who changed which fields while you had it open, and lets one agent claim a ticket so the rest of the team sees it is taken. It runs entirely on Atlassian, so no data leaves your site.
Know who is on the ticket
Everyone viewing an issue shows in the side panel, live. The moment a teammate opens the issue you are on, an alert appears at the top of Jira, even with the panel closed.
- Appears in about a second, clears when they leave
- An alert at the top of the page, not hidden at the bottom
- Works on every issue, with nothing to add
Reload before you reply
If someone changes the status, the priority or the assignee, or adds a comment while you have the issue open, you see who changed which fields, with one click to reload.
- Names the person and the fields that changed
- Catches up on what changed while your tab was in the background
- Stops agents overwriting each other
Claim it, and everyone sees it
One click on “I’m handling this” puts a clear stop sign on the ticket for the rest of the team. The claim expires on its own, and a colleague can take over when they need to.
- A soft lock with automatic expiry
- Deliberate take-over, never by accident
- Customers on the portal are told when the team updated their request
See what it saved
Jira admins get a report of collisions spotted, changed-while-open warnings and claims over the last 30 days, per project, with the settings beside it.
- 30 days of activity, per project
- Turn alerts or the portal notice on and off
- Exclude projects and set how long a claim lasts

- Not on its own. Collision Guard adds it: everyone viewing an issue appears live in a side panel, and an alert appears at the top of Jira when someone else opens the issue you are on.
- It warns support agents when two of them are working on the same ticket, so they do not send two different replies or overwrite each other. Collision Guard does it with live presence, alerts and a claim that the rest of the team can see.
- No. Jira does not let apps block edits, so Collision Guard warns instead: it shows who is on the issue, tells you when it changes, and lets an agent claim it so the team knows it is taken.
- No. It is built on Atlassian Forge and runs entirely on Atlassian. It stores no field values, presence is never stored, and nothing is sent to Systematic or anyone else.
- It is free for sites with up to 10 users. Larger sites pay per user per month through the Atlassian Marketplace, from $1.00 down to $0.08 per user as the site grows, with a 30-day free trial.
- Not yet. Atlassian Forge apps do not run in the Jira mobile apps, so presence and alerts work in Jira on the web.
