No — and it's by design. Slack (owned by Salesforce) and Google Chat (part of Google Workspace) are direct commercial competitors. Neither company has built a native messaging bridge between the two platforms. A message sent in Slack stays in Slack. A message sent in Google Chat stays in Google Chat.

This guide explains exactly why the gap exists, who needs it bridged, and how to set up real-time bidirectional Slack↔Google Chat channel messaging with SyncRivo — with full thread context, identity resolution, and SOC 2 compliance — in under 20 minutes.

Native Slack↔Google Chat: What's Possible and What's Not

Native options — limited

Zapier / Make: one-way message forwarding via webhooks
Slack email integration: forward Google Chat digest emails into Slack
Slack RSS: subscribe to Google Chat activity feeds (read-only)
Shared Google Drive files accessible from both platforms

Not possible natively

Real-time bidirectional channel message routing
Reply in Slack, see the reply in Google Chat (and vice versa)
Thread fidelity — replies stay in the correct thread
@mentions that resolve to real identities across platforms
File and attachment transfer between channels and spaces
Channel-to-space mapping with per-message routing rules

Who Needs Slack ↔ Google Chat Channel Messaging

M&A: Slack-Native Startup + Google Workspace Acquirer

A startup built entirely on Slack (with deep Jira, GitHub, PagerDuty integrations) gets acquired by a Google Workspace organization where all collaboration happens in Google Chat spaces. Forcing the startup's team to migrate immediately destroys workflow integrations and disrupts operations. SyncRivo bridges both organizations's channels on Day 1, giving IT time to plan a longer-term rationalization.

Agency ↔ Enterprise Client Collaboration

A digital agency runs its internal team on Slack. Its enterprise client operates Google Workspace across all departments. Daily project collaboration requires the agency team and client team to communicate in real time. SyncRivo maps the agency's Slack project channels to the client's Google Chat spaces — both sides see messages natively without switching platforms or sharing guest access.

Internal Platform Split

Engineering and product teams adopt Slack for its developer integrations (GitHub, Jira, PagerDuty). Marketing, sales, HR, and finance run on Google Workspace and default to Google Chat. Internal cross-functional projects — launches, incidents, hiring — require both groups to collaborate. SyncRivo routes messages between the Slack engineering channels and Google Chat business spaces.

Education and Research

Universities where research labs and CS departments use Slack (GitHub, Jupyter, data pipeline integrations) need to communicate with administrative offices standardized on Google Workspace for Education and Google Chat. SyncRivo bridges faculty research Slack channels to administrative Google Chat spaces — FERPA-supportive architecture with zero message storage.

Bridge Slack and Google Chat in 5 Steps (20 Minutes)

No code required. SyncRivo connects to both platforms via their official APIs.

1
Authorize Slack via OAuth2
In SyncRivo, click "Add Platform," select Slack, and sign in with your Slack workspace admin credentials. Install the SyncRivo Slack app to your workspace and grant channels:read, chat:write, and incoming-webhook permissions. SyncRivo connects with least-privilege scoped tokens.
2
Authorize Google Chat via Google Workspace Admin
In SyncRivo, click "Add Platform," select Google Chat. Follow the guided flow to create a Google Cloud service account, enable the Google Chat API, and grant chat.messages and chat.spaces permissions. Approximately 7 minutes with Google Workspace admin credentials.
3
Map Slack channels to Google Chat spaces
In the SyncRivo dashboard, pair Slack channels with Google Chat spaces using the visual mapping interface. Configure sync direction (bidirectional or one-way) and which message types route. You can create custom routing rules by channel, sender, or message content.
4
Configure identity resolution
SyncRivo matches users across platforms by email address. Review the identity map to ensure each Slack user resolves correctly to a Google Chat counterpart. Messages appear attributed to the real sender name — not a bot label — on both sides of the bridge.
5
Test and go live
Send a test message in a Slack channel and verify it appears in the mapped Google Chat space within seconds. Reply from Google Chat and verify the reply shows in the Slack channel thread. Enable the bridge for all mapped channels.
