| 41 | ## Description |
| 42 | |
| 43 | Typical use scenarios: |
| 44 | |
| 45 | * archive your private conversations from Slack when the administrator |
| 46 | does not allow you to install applications OR you don't want to use |
| 47 | potentially privacy-violating third-party tools; |
| 48 | * archive channels from Slack when you're on a free "no archive" subscription; |
| 49 | so you don't lose valuable knowledge in those channels; |
| 50 | * create a Slack Export archive without admin access; |
| 51 | * create incremental Slack archives, which is particularly useful for free |
| 52 | workspaces with 90-day limits; |
| 53 | * save your favourite emojis; AND |
| 54 | * analyse you Slack data with AI Agent using [Slackdump MCP Server](#slackdump-mcp-server). |
| 55 | |
| 56 | There are several modes of operation |
| 57 | |
| 58 | 1. List users/channels |
| 59 | 1. Dumping messages and threads |
| 60 | 1. Creating a Slack Export in Mattermost or Standard modes. |
| 61 | 1. Creating an Archive (Sqlite database or stored as json+gz) |
| 62 | 1. Converting an archive to other formats (Export, Dump). |
| 63 | 1. Emoji download mode. |
| 64 | 1. Viewing Slack export, dump or archive files or directories (displays images). |
| 65 | 1. Search mode (messages and files). |
| 66 | 1. Resuming previous archive (adding new messages to an existing archive). |
| 67 | 1. Local MCP Server to use with Opencode, Claude, or any other AI tool |
| 68 | supporting mcp over STDIO or HTTP. |
| 69 | 1. Database tools: merge multiple archives, remove duplicates, and clean up |
| 70 | unfinished sessions (`slackdump tools merge/dedupe/cleanup`). |
| 71 | |
| 72 | Run `slackdump help` to see all available options. |
| 73 | |
| 74 | ## Installation and Quickstart |
| 75 | |
| 76 | On macOS, you can install Slackdump with Homebrew: |
| 77 | |
| 78 | ```shell |
| 79 | brew install slackdump |
| 80 | ``` |
| 81 | |
| 82 | On other Operating Systems, please follow these steps: |
| 83 | |
| 84 | 1. Download the latest release for your operating system from the [releases] page. |
| 85 | 1. Unpack the archive to any directory. |
| 86 | 1. Run the `./slackdump` or `slackdump.exe` executable (see note below). |
| 87 | 1. You know the drill: use arrow keys to select the menu item, and Enter (or |
| 88 | Return) to confirm. |
| 89 | 1. Follow these [quickstart instructions][man-quickstart]. |
| 90 | |

| 92 | |
| 93 | > [!NOTE] |
| 94 | > On Windows and macOS you may be presented with "Unknown developer" window, |
| 95 | > this is fine. Reason for this is that the executable hasn't been signed by |
| 96 | > the developer certificate. |
| 97 | |
| 98 | To work around this: |
| 99 | |
| 100 | - **on Windows**: click "more information", and press "Run |
| 101 | Anyway" button. |
| 102 | - **on |
