SlArchive — Browse Your Slack History

Don't get trapped in Slack's weird export format

What it does

Drop your Slack export ZIP into slarchive.com and instantly browse your entire workspace history — channels, DMs, threads, reactions, and search — all processed locally in your browser. Nothing is uploaded. No account required. Your data never leaves your device. Export any channel to HTML, Markdown, or JSON when you're ready to migrate. Free and open source (MIT). Built by David Liedle.
