Interstellar

Interstellar is the most feature rich and user-friendly discord bot for space-themed discord servers out there. If you're interested into the rockets, astronomy, playing Kerbal Space Program, or just simply looking at some pretty space pictures, Interstellar will provide you with everything you need! With over 20 commands, auto-posting for the Astronomy Picture of the Day and reminders for Rocket Launches, all customisable via it's web dashboard which lets you change how the bot fundamentially behaves, the possibillities are endless for Interstellar. Interstellar was written by a space enthusiast so you know it will have a lot of care and attention put into it's features.
If by chance Interstellar doesn't have what you're looking for, request it on our - Gitlab or in our Support Discord, We aren't afraid to add stuff. 99.9% of the features we've added are from user suggestions, so don't be afraid!

Donations

Interstellar doesn't require a payment or any kind of action to use, you simply invite it and configure it to your liking. This doesn't mean it's free for us to maintain. Interstellar is quite an expensive project to keep alive, as we have to pay for servers, web hosting, and ensure it has enough resources and maintanence to keep up with requests. To help us out, you could donate to the guy who runs it here - they're greatly appreciated and help out tremendously with costs. Even the smallest amount is welcome <3

If you can't donate, simply voting for the bot every now and then helps out a lot too! A lot more than you might think :)

Start-Up Guide

To begin using Interstellar, you first need to invite it into your server. If you don't want to modify Interstellar in any way, that's all it takes!

To configure Interstellar, you must be the server owner for security reasons. To continue, go to Interstellar's Website. Log in with the top-right log in button, and go the Dashboard from the navigation bar. The Dashboard will show you all of the servers that you own that also have Interstellar invited to them. Select the one you wish to edit and click "edit server". You'll be redirected to the edit settings page.
In the Settings Page, you can see all the 'categories' of settings you can edit on the side. Click one and it will take you to the settings for that specific part of Interstellar's functionality. After editing your settings, remember to click 'Save Settings' at the bottom and wait up to a minute for them to apply. It's that simple!

Where can I suggest features or report bugs?

Just shout out your ideas in Interstellar's Support Discord and I'll happily listen. Alternatively, you can use Interstellar's Gitlab Issues Page.
Interstellar's Gitlab Page is where you can keep track of what I'm adding, when I'm adding it, and how far along I am in adding it. You can easily make an issue there to suggest a feature or report a bug if you have a gitlab account.

I'm more of a visual learner. Any pictures?

Absolutely! Here you go!
