Custom Discord bots
Plenty of servers need one thing no public bot does quite right. A custom bot is built for that one job and set up for your channels and roles.
How a custom bot works
Most custom bots start from a specific annoyance. A staff team reviews applications in DMs and loses track, so they want a form that opens in a pop-up and posts the answers to #applications with Accept and Deny buttons. A streamer wants an alert in #announcements when they go live on Twitch. A game community wants its server's player count shown in a channel name.
These are all ordinary bot work, but each has a Discord detail worth knowing. Pop-up forms, called modals, hold at most five fields. Channel names can be changed only twice every ten minutes, so a status counter updates on a slower rhythm than you might expect. Stream alerts need the platform's API, which usually means creating a free developer key with Twitch or YouTube.
Write down what should happen, in which channel, and who is allowed to trigger it. That description is the spec. Starting from a template saves time when your idea is close to a ticket, welcome or moderation bot, and starting from scratch is fine when it is not. On Discord Bot Creator the bot is built and hosted from what you write, and you can change it later by asking in the same chat.
What it usually does
- Collects applications through a pop-up form and posts them for staff review
- Posts an alert when a streamer goes live or a new video goes up
- Keeps a sticky message at the bottom of a busy channel
- Shows a game server's status or player count
- Opens a thread for each post in a feedback or suggestions channel
- Runs commands that only make sense in your server
Permissions and intents it needs
Give a bot only what it uses. These are the permissions a typical custom bot asks for in its invite link, and why.
| Permission | Why |
|---|---|
| View Channels | Sees the channels the bot works in. Most custom bots need little more than this. |
| Send Messages | Posts alerts, form results and replies. |
| Embed Links | Formats alerts and application results as embeds. |
| Read Message History | Finds and edits its own earlier posts, like a sticky message or status panel. |
Privileged intents
None needed for a typical custom bot.
Depends on what the bot does. Bots built on slash commands, buttons and forms need none; reading chat needs Message Content Intent and reacting to joins needs Server Members Intent, both under Developer Portal → your app → Bot → Privileged Gateway Intents.
Custom bots built here
Real bots made by describing them, running in Discord servers now.
No custom bots are listed yet. Bots appear here once they have been online for three days and joined a server. Yours could be the first.
Describe yours like this
Name the channels, roles and commands you want. The more specific the description, the less you need to change afterwards.
I need a bot for staff applications. /apply opens a form asking age, timezone, why they want to join staff and past experience, then posts the answers in #applications with Accept and Deny buttons for @Admins. Accept gives the @Trial Mod role and DMs the applicant; Deny DMs them a short reason.
Questions about custom bots
Can I make a Discord bot that does something no other bot does?
Usually yes, as long as Discord's API allows it. Bots can post and edit messages, manage roles and channels, open forms, react to joins and voice activity, and call outside services. They cannot read private messages between members, join servers nobody invited them to, or do anything beyond the permissions you give them.
How do I describe a custom bot so it comes out right?
Say what triggers each action, what the bot does, where it happens and who can use it. "When someone runs /apply, open a form with these four questions and post the answers in #applications for @Admins" is buildable. "Make an application system" leaves too much to guess. Name channels and roles exactly as they appear in your server.
Can a custom Discord bot connect to Twitch or YouTube?
Yes. The bot calls the other site's API on a schedule or when a command runs. Most need a developer key: Twitch asks for a client ID and secret, YouTube for a Data API key, and both are free to create. Some sites have no public API, and a bot should not scrape those against their terms.
Is a custom bot harder to keep running than a template?
Not if it is hosted. The work is in getting the behavior right, which is easier with a clear description. After that a custom bot restarts, logs and updates like any other. The main extra care is outside services: if Twitch or a game server changes its API, the bot may need an update.
Other kinds of Discord bots
Describe the custom bot your server needs
Write it in a sentence or two. You see the plan before anything is built, and your first bot runs free for 7 days.
