Cross-post from Meta.Discourse.org: (Obviously, swapping Flarum for Discourse here) because I was actually curious and couldn't find a specs list.
I would expect this to run somewhat well even under a wimpy setup, but was curious what the devs had to say.
OP copy-pasta'd below for context:
I’ve seen it rehashed in a few topics, but I wanted to make sure I have my understanding is correct on this.
I’d like to host Discourse as the modern forum frontend for a (very small) discussion board for my YouTube channel (we have a Discord server, but endless walls of text and images gets really messy after a while).
I really like the UI of Discourse and would like to try installing it to try it out, but the docs mention 1 Gb being a minimum (and with that size swapping is mandatory). I really don’t have the money to spare (especially not with the YouTube adsense drama cutting everyone off) and can’t afford an extra $20/mo for an idea.
I’ve seen other forums out there that try to more or less emulate what Discourse is doing but with smaller requirements (much better!) like NodeBB with fewer required software packages and the memory requirement is 512Mb (apparently without needing swap? Docs don’t really say), or even Flarum (doesn’t even mention a memory requirement, though since it’s only PHP+Mysql I can assume it would run fine in way under 512 Mb).
I know, obviously getting a super-beefy host with gigarams and megabits would be preferred, but I just don’t have the cash on hand for this.
Am I barking up the wrong tree looking to have the best experience on a 512 Mb (or less) server? Or does someone know a good host I can use for $5 or less that can adequately run Discourse?
