Slack already wiped workspaces across China, Hong Kong, and Macau. Thousands of teams have permanently lost years of messages, files, and institutional knowledge. If you still have access, back up now.
Export everything. Keep it forever. Make it searchable with AI.
A timeline of how Slack left thousands of teams stranded.
Slack notifies users in mainland China, Hong Kong, Taiwan, and Macau to "migrate to Alibaba Cloud" by February 2026. Many users report never receiving the email — it went to spam.
The Alibaba Cloud migration option turns out to be non-existent for most users. Smaller teams receive straight termination notices with no migration path.
Slack cut off all access. Users in China, Hong Kong, and Macau lost access to messages, files, channels, and integrations.
Slack has already permanently deleted data for many workspaces. Messages, files, threads, and user profiles are being wiped on a rolling basis. Some workspaces still have data remaining — but the window is closing fast.
No admin access required. Export locally, browse offline, and soon — AI-searchable.
Run the interactive wizard to download all your messages, threads, files, and user data. It handles authentication for you — no admin privileges needed. Private channels, DMs, files, everything.
The wizard handles login, channel selection, and export format. No manual tokens needed. Your data is saved as a local ZIP file.
View your exported Slack history in a familiar, readable format. Slackdump includes a built-in viewer, or convert to browsable HTML.
Export is also compatible with Mattermost and Discord importers if you're migrating platforms.
We're building an integration with Teamily AI to transform your Slack export into an AI-native workspace. Ask natural language questions, discover connections, and chat with your history — with AI agents as first-class participants.
Teamily AI is the world's first human-AI social network, with a universal memory layer that preserves your team's context.
Everything you had access to in Slack.
All messages, threads, and reactions from every public channel you're in.
Private channel history that you have access to — no admin needed.
All your 1:1 and group DM conversations, complete with threads.
PDFs, images, documents, code snippets — everything shared in channels.
Names, avatars, email addresses, and status info for all workspace members.
Complete thread context preserved, not just top-level messages.
We're integrating with Teamily AI to transform your exported Slack history into an AI-native workspace. Ask questions, discover connections, and keep your team's institutional memory alive — with AI agents working alongside you.

Teamily AI's memory layer preserves context across all conversations — your Slack history becomes permanent team knowledge.
Ask natural language questions and get answers sourced from your actual Slack conversations, with AI agents as first-class participants.
Move from Slack to a next-generation messenger where your team's history and knowledge carry forward.
No. Slackdump works with your personal user token. You can export any channel, DM, or file that you personally have access to.
If you still have a valid session token (d-cookie) from before termination, Slackdump may still be able to pull data — but Slack has already deleted many workspaces. Act immediately, as the remaining data could disappear at any time.
The tool works for any Slack workspace globally. But the urgency is highest for Greater China users who are facing forced termination and data loss.
Your Slack export runs entirely on your local machine with Slackdump, which is open source. No data is sent to any third party during export. You own your data.
Slackdump can output in Slack-compatible export format (JSON + files in a ZIP), which works with Mattermost, Discord importers, and Teamily AI.
Depends on workspace size. A typical workspace with 10K messages takes a few minutes. Large workspaces with 100K+ messages and lots of files may take 30-60 minutes.
Slack has already deleted data for thousands of workspaces. If yours is still intact, back up your Slack history today.
Once it's gone, there's no getting it back.
