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.

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.

Capability Threadmaker Jira Cloud for Slack (Atlassian official) Unito (2-way sync)
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
Channel ↔ project mapping Yes — admin /jira-map No — per-user subs Yes
Audit log (admin-accessible) 90 days No Yes
Pricing (50-user team, entry tier) $75 / mo Free $99–769 / mo

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 → minutes

Customer 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 thread

On-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-day

Common questions

Things buyers ask before clicking install

Can I uninstall cleanly without losing data?
Yes. Uninstall from Slack OR from Jira at any time. Existing anchor messages stay in Slack; existing Jira comments stay on tickets. Your backend data (workspace records, mappings) is deleted automatically on the 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?
The Slack app is free, forever. The Jira side is billed by Atlassian Marketplace per Jira-side user, with three paid tiers and a free tier for up to 10 Jira users (see Pricing). The Atlassian Marketplace listing is the canonical source for current pricing parameters and seat thresholds — your Atlassian admin's existing billing channel applies them automatically. All tiers include every feature — bidirectional sync, edits/deletes, attachments, mention mapping, audit logs, GDPR-compliant DPA. Atlassian collects payment; we receive monthly statements. No additional Threadmaker invoicing — your existing Atlassian billing channel is the single source of truth.
What if Slack or Jira is briefly down?
Each comment is durably queued and retried up to 5 times with exponential backoff (1 → 2 → 4 → 8 → 16 minutes; ~31 minutes of retry-window total). If all 5 attempts fail, you get a failure alert in your configured alerts channel. The failed-row record stays in our retry queue for 30 days for forensics — separate from the audit log, which keeps every sync event for 90 days (admin-accessible via /jira-audit). The queue is per-tenant, so a noisy neighbour can't starve your delivery. See troubleshooting for the common failure modes.
How large can attachments be?
Up to 5 files × 2 MB per comment. Images render inline in the Jira comment body (PNG / JPEG / GIF / WebP). Files over the cap are dropped with an ephemeral warning to the Slack uploader so they know what happened. For larger files, paste a link to your team's storage. See attachments for the full picture.
Is my data shared with anyone?
We use four sub-processors: Cloudflare (compute), Atlassian (Forge runtime + billing), Slack (Events API), and Sentry (error reporting, payloads scrubbed of secrets). We never store Jira API tokens, never train AI on your data, never sell or aggregate across tenants. Full list: /privacy/subprocessors.
Does it work with Slack Enterprise Grid?
Not in v1.x — currently single-workspace only. Enterprise Grid support is scheduled for Q3 2026. If you're a Grid customer interested in early access, email contact@threadmaker.dev.
