Val Town is a collaborative website to write and scale serverless JavaScript.

Create APIs, crons, and store data – in your browser, deployed in milliseconds.

If you're new to Val Town and want to learn the core building blocks first, read: What is a val?

If you'd rather jump right into the code, remix this val: hello-val

We also have starter guides for:

• Your first HTTP endpoint
• Your first cron val

Edit your vals from your favorite IDE (VSCode, Cursor, vim, etc) via our CLI.

• Val Town CLI: Deploy vals from your terminal
• LLM Prompting: Edit vals with Claude Code, Cursor, et al

Our standard library includes some hosted services for data storage, email, and AI.

• SQLite: Store and retrieve structured data
• Blob: Store and retrieve any data
• OpenAI: Use the OpenAI API
• Email: Send emails

• REST API: Access Val Town programmatically
• JavaScript SDK: Interact with Val Town from JavaScript
