Why teams connect GitHub and Slack

Stop re-entering the same information in GitHub and Slack: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Releases, Workflow runs (Actions), Organizations and Teams, Users in GitHub with Users, User groups, Files, Reactions in Slack in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • Mirror repository, PR, and workflow-run data into a Postgres database for engineering-metrics reporting.
  • Sync organization and team membership with an identity or HR system to automate access reviews and offboarding.
  • Post CRM record changes into deal or account channels so the team sees updates without opening the CRM
  • Sync the Slack user directory with the HRIS or identity provider to keep memberships and profiles current

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

Where Slack is where the team documents or plans: keep its data fed

Information that originates in GitHub stays current in Slack instead of going stale after a one-time paste.

What you can sync between GitHub and Slack

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

GitHub objects Slack objects
Pull Requests Review state, status checks, and merge status feed engineering dashboards and workflow tools. Users Workspace members with profile fields, synced against HR systems and identity providers.
Commits Read-only history used to link code activity to tickets and releases. User groups Handles like @support that map to teams in external systems.
Releases Tagged versions synced into changelogs, CRMs, or customer-notification systems. Files Uploads attached to messages, retrievable for archiving.
Workflow runs (Actions) CI results synced into incident and reporting systems. Reactions Emoji responses that can drive workflows, such as approving a synced record.
Organizations and Teams Membership data synced with identity systems and HR directories for access reviews. Channels Conversations (public, private, DMs) that messages are read from and posted to.
Users Author and assignee identities matched to internal directories. Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods.
