Deep Dive: Switching from Slack Pro to Pumble Free
Trade-offs, installation & data architecture
What you trade away
Pumble Free keeps unlimited users and history, but group meetings, screen sharing, integration breadth, storage, and Slack's huge app ecosystem are materially weaker.
How to deploy Pumble Free
Hosted signup; use the browser or Pumble's desktop/mobile apps
What it takes to run
There is no installation hurdle, but migration still requires inviting everyone and rebuilding channels and integrations; free exports exclude private channels and direct messages.
Where your data lives
Messages, channels, user records, and files live in Pumble's cloud; workspace owners can export public-channel data as a ZIP with message data and file links.
Why fork Pumble Free instead of vibe-coding a Slack Pro clone?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Slack Pro, run a small private team chat with channels, threads, files, and search. The hard boundary is existing team network, integrations, push delivery, enterprise controls, and global reliability, plus network, moderation, and communication infrastructure.
