OPEN SOURCE CLI GENERATOR

BUILD CLIs AT
WARP SPEED

Define your CLI in one bao.toml file.
Generate Rust and TypeScript CLIs.
Simple, instant and zero boilerplate.

DOCS
bao.toml
> bao bake --language rust

WHY BAO?

CLI development made easy

WITHOUT BAO
PAINFUL
  • ✗ Write argument parsing boilerplate for every command
  • ✗ Manually sync CLI structure across Rust and TypeScript
  • ✗ Rewrite handler scaffolding every time you add a command
  • ✗ Pass shared state manually through every function
  • ✗ Hope your args and flags stay consistent across refactors
WITH BAO
SIMPLE
  • ✓ Define your CLI once in bao.toml
  • ✓ Generate idiomatic Rust (clap) or TypeScript (boune) code
  • ✓ Handler stubs auto-generated — just fill in your logic
  • ✓ Typed context object for database pools, HTTP clients, etc.
  • ✓ Re-run bao bake anytime — your code is preserved

HOW IT WORKS

Three simple steps

READY
01
INITIALIZE REQUIRED
▶ bao init myapp --language rust

Creates project structure with bao.toml manifest

02
ADD COMMANDS OPTIONAL
▶ bao add command deploy

Interactively add commands, args, and flags to your manifest

03
GENERATE FINAL
▶ bao bake

Generate type-safe code with handler stubs. Run again anytime — your code is preserved!

CODE GENERATION

One config, multiple outputs

INPUT
bao.toml 
[cli]
name = "deploy-cli"
version = "1.0.0"

[commands.deploy]
description = "Deploy to environment"
args = ["environment"]
flags = ["force", "dry-run"]

[commands.status]
description = "Check deployment status"

[context]
fields = ["config", "client"]
OUTPUT 
#[derive(Parser)]
#[command(name = "deploy-cli")]
pub struct Cli {
    #[command(subcommand)]
    pub command: Commands,
}

#[derive(Subcommand)]
pub enum Commands {
    /// Deploy to environment
    Deploy {
        environment: String,
        #[arg(long)]
        force: bool,
        #[arg(long)]
        dry_run: bool,
    },
    /// Check deployment status
    Status,
}
