One Slack thread per Jira ticket
Bidirectional sync of edits, attachments, mentions. The conversations integration, not notifications.
Map a channel to a Jira project. Every ticket gets its own thread. Comments sync both ways — with edits, attachments, and mentions intact.
Free for up to 10 Jira users · Cancel anytime · No credit card required
Atlassian Marketplace listing under review — public availability ~2-4 weeks after submission.
Why Threadmaker
Notifications tell you what happened. Conversations let you respond.
By Friday, no one remembers what was decided.
Most Jira-Slack integrations push a notification when something changes. Your team reads it, talks about it in a separate channel, and the discussion never makes it back to the ticket. Threadmaker gives every issue its own Slack thread — and the conversation lands on the ticket automatically.
Three steps. Under ten minutes.
From install to first synced comment.
Install both apps
You add Threadmaker from the Atlassian Marketplace and the Slack App Directory, then paste the connection token from Slack into Jira admin once. Two windows; no API tokens to manage.
Map a channel to a project
A workspace admin runs /jira-map in any public or private Slack channel and picks a Jira project. The bot needs a member-invite either way (Slack rule, not ours).
Start working
Every new ticket gets its own Slack thread. Replies sync both ways within seconds — edits, deletes, attachments, and mentions all intact. Your team writes on the side they're already on.
What you get
Built for the way your team already works.
Bidirectional comment sync
Replies in Slack become Jira comments. Comments in Jira appear in the right Slack thread. No double-posts, no echo loops.
Edits and deletes sync both ways
Fix a typo in Jira; the Slack thread updates within seconds. Delete a wrong comment in Slack; it disappears from the ticket too. Both sides stay clean.
Inline images and attachments
Drop a screenshot in Slack; it renders inline inside the Jira comment body — not just in the attachments tab. Up to 5 files × 2 MB per comment.
Anchor messages stay live
Status changes in Jira show up in the Slack thread automatically. No stale "is this still in progress?" pings — the header re-renders the moment Type, Status, Priority, or Assignee change.
How we stack up
Here's where we win, and where we don't.
JC4S is the official free option. Unito is the multi-tool generalist. Threadmaker is the only one that gives every issue its own conversation thread — and syncs it bidirectionally without losing edits, attachments, or context.

|---|---|---|---|
| One Slack thread per issue, auto-created | Yes | No — channel notifications | No — record-level |
| Slack replies become Jira comments | Yes | No — manual /jira |
Yes, delayed |
| Edits and deletes sync both ways | Yes | No | 2–15 min lag, may orphan |
| Attachment binary sync, both directions | 5 × 2 MB | Links only | No |
| Inline image rendering in Jira comments | Yes | No | No |
| Mention mapping (@user ↔ @user) | Yes | One-way unfurl | Record-level |
| Live anchor (status / assignee re-renders) | Yes | One-shot unfurl | No |

If you need free or generic record-sync across many tools, JC4S and Unito are honest answers. If you need the conversation to land on the ticket, Threadmaker is the only one built for that.
Built for your team
Three teams, one pattern.
Engineering triage
You file bugs in Jira and triage them in Slack. Threads stay open; tickets accumulate the discussion automatically. No more "hey, did you see this?" chase messages.
Time-to-first-response: hours → minutesCustomer support escalation
You escalate to engineering in-thread. The Jira ticket accumulates the diagnostic trail without anyone retyping context. Engineers stay in Slack; the audit trail builds itself.
Handoff: from a chase, to a threadOn-call & incident response
You jump into the war-room channel. The anchor message tracks status / assignee / priority live. After the incident, the thread IS the postmortem — Jira is the durable copy.
Postmortem: days → same-dayPricing

Common questions
Things buyers ask before clicking install
Can I uninstall cleanly without losing data?
app_uninstalled event — typically within minutes;
a 30-day SLA upper bound covers any retry-window delay, per
Privacy Policy §4.2. No exit fees, no
per-seat lock-in. To request immediate erasure (Article 17), email
dpo@threadmaker.dev with subject "Data deletion request".
How does pricing work?
What if Slack or Jira is briefly down?

queue is per-tenant, so a noisy neighbour can't starve your
