Build & Sell Automation Scripts on the Cereal Marketplace

Every automation developer eventually hits the same wall: you write a useful script, and then what? Sharing it is messy. Monetizing it is worse. Building UIs, handling licensing, distributing updates, preventing piracy — none of this is fun, and none of it pays unless you build your own infrastructure.

Cereal is a complete platform that lets you build, package, distribute, and monetize automation scripts with almost no overhead. Whether you’re building new workflows with the Kotlin-powered Cereal SDK or publishing existing scripts to the Marketplace, Cereal gives you the tools to turn your automation work into real products.

Why Developers Build for Cereal

• Monetize immediately with subscription pricing, free trials, and promotion codes built in.
• Build in Kotlin with strong typing, modern tooling, and automatic UI generation.
• Publish professionally with versioning, release channels, maintenance mode, and analytics.
• Protect your code with secure licensing, cryptographic key pairs, and ProGuard obfuscation.
• Reach buyers through the Cereal Marketplace, built specifically for automation scripts.

Monetization That Works Out of the Box

Most platforms ask you to bring your own payment system, licensing logic, and customer management. Cereal handles all of it.

Marketplace revenue features:

• Subscription-based pricing you control
• Free trials to improve conversion
• Promotion codes for marketing campaigns

Integrated licensing and protection:

• Each script gets a public/private key pair
• Digital signatures verify legitimate subscriptions
• ProGuard obfuscation protects your code from decompilation

No piracy headaches. No auth servers to maintain.

A Kotlin-First Developer Experience

Cereal is built by developers who know the pain of weak typing and config chaos.

Why Kotlin?

• Strong typing and null safety
• IntelliJ and Android Studio support
• JVM ecosystem
• Clean coroutine-based async patterns

Built-in components — no boilerplate:

• NotificationComponent (including Discord and Telegram webhooks)
• PreferenceComponent for local persistence
• UserInteractionComponent for prompts and dialogs
• LoggingComponent with structured logs
• LicenseComponent for subscription verification

Auto-Generated Configuration UIs

Building UI is often the worst part of scripting. Cereal eliminates it. Define your config interface in Kotlin, and the Cereal desktop client auto-generates a polished settings screen.

interface MyScriptConfig : ScriptConfiguration {
    @ScriptConfigurationItem(
        keyName = "targetUrl",
        name = "Target Website",
        description = "The URL to automate",
        defaultValue = "https://example.com"
    )
    fun targetUrl(): String
}

Your scripts feel like professional software without any frontend work. Need conditional UI? Use State Modifiers to show, hide, or validate fields based on user input.

Simple, Professional Distribution

Cereal handles the entire distribution pipeline.

Developer Dashboard:

• Release channels (stable, beta, and more)
• Maintenance mode to message users immediately
• Unlisted releases for soft launches and private testers
• Full version history

Gradle-based packaging:

• Standard Gradle project structure
• ProGuard obfuscation included
• Output is a single JAR — no dependency hell, no zip files

Cereal vs. Traditional Script Development

A Working Cereal Script

class MyScript : Script<MyScriptConfig> {
    override suspend fun onStart(config: MyScriptConfig, provider: ComponentProvider): Boolean {
        provider.logger().info("Script started!")
        return true
    }

    override suspend fun execute(
        config: MyScriptConfig,
        provider: ComponentProvider,
        statusUpdate: suspend (String) -> Unit
    ): ExecutionResult {
        statusUpdate("Working...")
        provider.logger().info("Automating ${config.targetUrl()}")
        // Do some work...
        return ExecutionResult.Loop("Waiting for next run", 5000)
    }

    override suspend fun onFinish(config: MyScriptConfig, provider: ComponentProvider) {
        provider.logger().info("Script stopped.")
    }
}

This is all you write. The SDK, Marketplace, UI, licensing, and distribution pipeline handle everything else.

Who Should Build for Cereal?

Cereal is a good fit for:

• Automation engineers
• Existing script authors (Python, JS, Batch, PowerShell)
• Kotlin developers
• Indie developers looking for passive income
• Anyone who builds tools to automate repetitive tasks

If you can write scripts, you can make them profitable.
