[!WARNING]

Enterprise Workspaces Security Alerts

Depending on your Slack plan and security settings, using Slackdump may trigger Slack security alerts and/or notify workspace administrators of unusual or automated access/scraping attempts.

You are responsible for ensuring your use complies with your organisation’s policies and Slack’s terms of service.

See Enterprise Workspace Tips.

Description

Typical use scenarios:

archive your private conversations from Slack when the administrator does not allow you to install applications OR you don't want to use potentially privacy-violating third-party tools;
archive channels from Slack when you're on a free "no archive" subscription; so you don't lose valuable knowledge in those channels;
create a Slack Export archive without admin access;
create incremental Slack archives, which is particularly useful for free workspaces with 90-day limits;
save your favourite emojis; AND
analyse you Slack data with AI Agent using Slackdump MCP Server.

There are several modes of operation

List users/channels
Dumping messages and threads
Creating a Slack Export in Mattermost or Standard modes.
Creating an Archive (Sqlite database or stored as json+gz)
Converting an archive to other formats (Export, Dump).
Emoji download mode.
Viewing Slack export, dump or archive files or directories (displays images).
Search mode (messages and files).
Resuming previous archive (adding new messages to an existing archive).
Local MCP Server to use with Opencode, Claude, or any other AI tool supporting mcp over STDIO or HTTP.
Database tools: merge multiple archives, remove duplicates, and clean up unfinished sessions (slackdump tools merge/dedupe/cleanup).

Run slackdump help to see all available options.

Installation and Quickstart

On macOS, you can install Slackdump with Homebrew:

brew install slackdump

On other Operating Systems, please follow these steps:

Download the latest release for your operating system from the releases page.
Unpack the archive to any directory.
Run the ./slackdump or slackdump.exe executable (see note below).
You know the drill: use arrow keys to select the menu item, and Enter (or Return) to confirm.
Follow these [quickstart instructions][man-quickstart].

[!NOTE] On Windows and macOS you may be presented with "Unknown developer" window, this is fine. Reason for this is that the executable hasn't been signed by the developer certificate.

To work around this:

on Windows: click "more information", and press "Run Anyway" button.
