Community FAQ

Questions by product

Google Chat FAQ

Can I self-host Google Chat or run it on my own servers for full data control?

No, Google Chat is a fully managed SaaS product integrated within Google Workspace and does not support self-hosting. All data is stored on Google's cloud infrastructure, and there is no option to deploy or run the service on-premises or on private servers.

Community insight informed by Reddit discussions

Does Google Chat support offline messaging or working without an internet connection?

Google Chat offers very limited offline functionality. While you can read recent messages cached in the app, composing or sending new messages requires an active internet connection. Offline message drafting is not supported, so full offline usage is not feasible.

Community insight informed by Hacker News discussions

Who owns the data shared in Google Chat and how is it managed within Google Workspace?

Data in Google Chat is owned by the organization using Google Workspace and is subject to Google's data processing terms. Administrators have control over retention policies, data export, and compliance settings via the Google Workspace Admin console. Google acts as the data processor under these agreements.

Community insight informed by StackOverflow discussions

What are the limitations of the Google Chat API for integrating custom workflows?

The Google Chat API allows sending and receiving messages, creating bots, and managing spaces, but it lacks advanced workflow automation features found in other platforms. It does not support complex event triggers or deep integration with third-party enterprise systems natively, limiting its use for sophisticated automation.

Community insight informed by Forums discussions

Is there a way to export or migrate chat history out of Google Chat for archiving or switching platforms?

Google Workspace admins can export Google Chat data using Google Vault if enabled, which supports retention and eDiscovery but does not provide a straightforward export format for migration. There is no native tool for bulk exporting chat history for migration to other platforms, making migration complex.

Slack FAQ

Is it possible to self-host Slack or run it on a private server?

Slack is a proprietary, cloud-based platform and does not offer an official self-hosted version. All Slack workspaces run on Slack's servers, so self-hosting is not supported. Organizations requiring on-premises solutions typically look at alternatives like Mattermost or Rocket.Chat.

Community insight informed by Reddit discussions

Does Slack support offline message access or offline functionality?

Slack's desktop and mobile apps cache recent messages for offline viewing, but full offline functionality is limited. You cannot send messages or access complete message history without an internet connection. Offline capabilities depend on cached data and are not comprehensive.

Community insight informed by Hacker News discussions

Who owns the data uploaded and shared within Slack workspaces?

Data uploaded to Slack remains the property of the organization or user who owns it, but it is stored on Slack's servers under their terms of service. Slack provides enterprise-grade security and compliance features, but ultimate data control is limited by Slack's cloud infrastructure and policies.

Community insight informed by StackOverflow discussions

What are the main API limitations when integrating custom apps with Slack?

Slack's API has rate limits that vary by endpoint, typically allowing a few hundred to a few thousand requests per minute per workspace. The API also restricts access to certain message types and historical data depending on plan level. Some advanced features require paid plans and OAuth scopes.

Community insight informed by Forums discussions

How can I export or migrate Slack data if I want to switch platforms?

Slack provides export tools for workspace owners: Standard and Plus plans allow exporting public channel data, while Enterprise Grid plans can export all messages including private channels and DMs with approval. Exported data is in JSON format, which can be used for migration, but no official import tools exist for other platforms.
