How often does Horizon get updates?

Horizon is a free-time project, so updates come whenever they're ready, sometimes more, sometimes less. I announce every update on the support server. Making the community happy is the part I enjoy most.

Where can I suggest a feature or report a bug?

On the support server. Feature requests and bug reports both go there.

Will Horizon stay free?

Everything that's free today stays free, that's a promise. A premium plan will come at some point, but nothing you can use for free now will move behind it. A few commands need a free vote on top.gg every 12 hours.

Is Horizon open source?

The bot's code isn't public. Sunrise, the proxy Horizon uses to talk to Discord's API, is open source though.

What is Horizon built with?

The bot is written in Kotlin with JDA. Its requests to Discord go through Sunrise, a REST proxy I wrote that keeps every shard within Discord's rate limits. This website runs on Next.js.
