I get the temptation to self-host your support platform, as the existing tooling out there can be quite expensive when you want to upgrade from just using an email inbox.

If any founders find themselves reading this, and don't think it's the best idea to self-host your own support infra, I've just spent the last 6+ months building stayupfront.com which has, I think, quite reasonable pricing, and a few more features than this... largely around the customer's portal experience (changelog, roadmap, etc.) and includes monitoring & incident management which I think should all be ran from the same surface.

I've only just soft-launched, so still have founding pricing on there. Would certainly love to speak to others in this space too, as I was surprised how neglected an area it seemed to be when I was trying to find a replacement for jira service desk for a company I was working with at the beginning of this year.
