Sanguine Hey, sorry for not being clear enough.
By DNS relay service, I meant having a way of programmatically manipulating the DNS table, pointing the internal subdomain to the custom one. I'm curious about how you implemented this because the TTL is practically instant.
About joining ya,
I see the big picture, there's a future for this project, besides I'm a fan of services that promote startups and small businesses. There are many ways I can help, as I'm a full stack dev...
I'm willing to help out on the website, it should look more like a SaaS platform and needs a better and more secure onboarding and in the nearest feature maybe work on the ease of accessibility for non-tech savvy users by building a multi-platform bot for managing accounts and instances from third-party apps like Slack, Telegram, Messenger and even for developers by building a CLI tool similar to Heroku CLI so they can do things like:
// Create an app
$ freeflarum create example-app
// Attach a domain to the app
$ freeflarum domains:add example-app.com
// Take the app down for maintenance
$ freeflarum pause example-app
I can also take a look at the feature request page if you'd prefer to start from rolling out features from there.
