Zulip is also, last I checked, the only ones who offer completely free, archive-enabled, hosted chat for open source projects ( https://zulip.com/for/open-source/ ). Mattermost has some kind of "out of the kindness of our heart" setup, but it requires applying for it ( https://docs.mattermost.com/about/license-and-subscription.h... ), and Slack appears to actually retain the archive content, but only makes it available for those who pay

Correct me if I'm wrong, but I think they're working on creating public chats, readable without logging in, from the browser?
Yes, the web-public view is being actively worked on: https://github.com/zulip/zulip/issues?q=label%3A%22area%3A+w...
There’s also a separate zulip-archive project that exports Zulip streams to static HTML: https://github.com/zulip/zulip-archive
