Berry is an ultra-lightweight dynamically typed embedded scripting language written in ANSI C99, designed for low-performance embedded devices like microcontrollers. It features a one-pass bytecode compiler and register-based VM with an interpreter core under 40KiB that can run in under 4KiB of heap.

Use cases

• embed a scripting language in a microcontroller firmware
• add user-scriptable logic to an embedded C application
• run dynamic scripts on devices with only a few KiB of RAM
• extend a host application with a lightweight FFI-based scripting engine
• script IoT devices like ESP32 or ARM Cortex-M boards

When to choose

• you need scripting on resource-constrained microcontrollers where Lua is too heavy
• you want an easy-to-embed C interpreter with a small footprint and FFI
• you need a dynamically typed language with OOP, functional, and imperative styles on embedded hardware

When to avoid

• you need a large ecosystem of libraries and package management
• you are targeting general-purpose application development on desktops or servers
• you need high raw performance from compiled native code
