The Verdict

Slack is worth the investment for teams that rely heavily on integrations, need enterprise features, or want a polished, fully-managed solution with extensive support.
How to switch from Streaming to Slack
- 1Export your data from Streaming using the admin Export Data feature, which generates a JSON archive of channel messages and a separate zip of uploaded files — download and store this locally before decommissioning anything.
- 2Create your Slack workspace and rebuild your channel structure to match Streaming, since Slack has no native importer for Streaming's export format.
- 3Manually re-upload critical files and pin important historical messages or summaries into the matching Slack channels, since full message-by-message import isn't supported without custom scripting against Slack's API.
- 4Recreate any webhooks or bot notifications from Streaming as Slack Incoming Webhooks or Slack apps, and rebuild recurring automations using Slack's Workflow Builder.
- 5Invite your team to the new Slack workspace and run both tools in parallel for 1-2 weeks so people can reference old Streaming history while adjusting to Slack.
- 6Set a hard cutover date, announce it in both tools, and archive or shut down the Streaming instance once everyone has confirmed they've copied over anything they still need.
Streaming vs Slack: common questions
How do I export my messages and files from Streaming before switching?+
Use Streaming's admin export tool to download your channel history, files, and user list as a data archive (typically JSON for messages, with files exported separately as a zip). If you're self-hosting, you can also pull data directly from the underlying database, but the built-in export is the safer path for most teams.
What features do I lose moving from Streaming to Slack?+
You lose self-hosting and full control over your data, since Slack is cloud-only. You'll also start paying per user for features that were free in Streaming, like unlimited file storage and full message history.
Is Slack's free plan enough for a small team of 5-10 people?+
It can work for very light use, but the 90-day message history limit and 5GB total file storage cap get restrictive fast for active teams. Most small teams that outgrow Streaming end up needing Slack Pro at $7.25/user/month to get full history and more storage.
What integrations can I set up in Slack that I didn't have in Streaming?+
Slack has a marketplace of over 2,600 apps, including Google Workspace, Jira, GitHub, Zoom, and Salesforce, plus native Workflow Builder for automations. Streaming only supports basic webhooks, so most teams end up rebuilding notifications and bot integrations from scratch in Slack.
How does the cost compare over time if I switch from Streaming to Slack?+
Streaming stays free indefinitely (or just hosting costs if self-hosted), while Slack Pro costs $7.25/user/month billed annually, or about $87/user/year. For a 10-person team, that's roughly $870/year that didn't exist before, so factor that into your decision if integrations aren't a hard requirement.
