Show HN: Create static HTML backups of your Slack workspaces

is this basically a free vrsn of this? https://www.backupery.com/products/backupery-for-slack/

MSN did this too. I still have logs of msn around 2008-2010 in html files.

this is great tool! even though the implementation for me would be too late a month.

I am sure, others will find this useful
