ZBR is a scripting language for Discord bots powered by a high-performance Rust runtime engine.
You write commands as plain .zbr files using ZBR functions, no boilerplate, no event handlers, no framework knowledge required.
Get your bot up and running in seconds:
Head over to the ZBR Webapp for a zero-setup development experience.
- Build your commands, manage variables, and tweak settings visually.
- Press Run to launch your bot instantly in the cloud for testing.
- Your bot is now live for testing!
Note: The Webapp "Run" button is strictly for rapid prototyping and interactive testing. For 24/7 production hosting, you must export your project as a ZIP and use the CLI.
- Install the CLI globally:
npm i -g @zbrlang/zbr
Some devices need an extra step if the CLI doesn't work after install, run:
npm config set ignore-scripts falseand than reinstall ZBR using the first command.
-
Initialize a new project:
zbr init my-bot
This creates your
commands/folder,zbr.jsonconfig, and a.envfile inside of my-bot. -
Navigate to your project directory
cd my-bot -
Configure your token: Open the
.envfile and paste your Discord Bot Token. -
Run the engine:
zbr run
Your bot is now live and loading scripts from the
commands/directory!
For those who prefer a visual development environment, the ZBR Webapp allows you to build and test your bot entirely in your browser.
- Instant Prototyping: Write code and launch your bot with a single click using the built-in cloud runner, no local setup required.
- Visual Interface: Easily design your bot logic, manage variables, and configure settings without touching a terminal.
- Hybrid Workflow: Use the Webapp for rapid development and testing, then export your project as a ZIP to host it permanently on your own server using the ZBR CLI.
#trigger !rank
#name Rank Command
#type prefix
Zvar{xp;ZgetUserVar{xp}}
Zvar{level;ZgetUserVar{level}}
Ztitle{Zusername's Rank}
Zdescription{Level: Zvar{level}
XP: Zvar{xp}}
Zcolor{#5865F2}
ZaddField{Server Rank;#Zvar{rank};true}
#trigger /ban
#name Ban Command
#type slash

#option user|User to ban|user|required
#option reason|Reason for the ban|string|optional
ZonlyIf{ZisAdmin==true;You need administrator permission to use this command}

Banned Zoption{user}.

Done.
ZBR is powered by a high-performance runtime engine built in Rust that parses and executes bot logic, and is distributed as a convenient npm CLI.
- The CLI (
zbr): Acts as your project manager and binary launcher. - The Engine: A bundled Rust binary that handles the Discord gateway, parses your
.zbrfiles, and executes logic in real-time. - Hot Reloading: The engine watches your
commands/folder. Save a.zbrfile, and the changes are live instantly without restarting.
Commands are plain text files. Each file has a header section (lines starting with #) that defines the trigger, name, and type, followed by the ZBR code that runs when the command is invoked.
| Type | Trigger format | When it runs |
|---|---|---|
prefix |
!command |
When a message starts with the trigger |
slash |
/command |
When a slash command is invoked |
interaction |
onInteraction{id?} |
When a button, select menu, or modal is submitted |
event |
onMessage, onMemberJoin, etc. |
When a Discord gateway event fires |
Functions are called with a Z prefix, followed by the function name and arguments in {} separated by ;.
ZfunctionName{arg1;arg2;arg3}
Functions can be nested — the inner call evaluates first:
Zsum{ZgetUserVar{xp};100}
Plain text on a line is output as-is. Functions and text can be mixed:
You have Zsum{ZgetUserVar{xp};0} XP.
Lines starting with // are comments.
- Embeds: Ztitle, Zdescription, Zcolor, ZaddField, ZsendEmbed, Zauthor, Zfooter
- HTTP: ZhttpGet, ZhttpPost, ZhttpPut, ZhttpPatch, ZhttpDelete, ZhttpResult
- Moderation: Zban, Zkick, Zmute, Ztimeout, Zclear, Zunban, ZvoiceKick
- Components: ZaddButton, ZaddSelectMenuOption, ZaddTextInput, ZaddUserSelect, ZeditButton, ZremoveComponent

- Servers: ZserverModify, ZserverLockdown, ZeditWelcomeScreen, ZwelcomeScreen, ZboostCount, ZboostLevel
- Channels: ZcreateChannel, ZdeleteChannels, ZmodifyChannel, ZsyncPerms, ZchannelExists, ZchannelName, ZslowMode
- Roles: ZcreateRole, ZdeleteRole, ZmodifyRole, ZroleMembers, ZroleExists, ZhasRole

The commands/ folder contains ready-to-run examples:
| File | Type | What it does |
|---|---|---|
ping.zbr |
slash | Replies with pong and echoes your input |
hello.zbr |
prefix | Greets the user with their name, channel, and server |
rank.zbr |
prefix | Reads user variables and sends a rank embed |
eval.zbr |
prefix | Evaluates ZBR code on the fly |
