It's open source! https://github.com/Flutterby-App/Flutterby

There's a companion project (that actually inspired this) that implements it so you can see it in action: https://github.com/devrelopers/repo-mood

Built this yesterday as a quick tool to solve a problem I've seen since 2017 — Slack exports are essentially unreadable JSON blobs with no good way to browse them.

SlArchive processes everything client-side in the browser using JSZip. Your export never touches a server. Drop the ZIP, browse channels, DMs, and threads, search across everything, then export to HTML, Markdown, or JSON if you need to migrate to another platform.

It's a single HTML file, MIT licensed, source at https://github.com/devrelopers/slarchive. Contributions welcome.
