Duktape is an embeddable JavaScript (ECMAScript E5/E5.1 with partial ES2015+) engine written in C, focused on portability and a compact footprint. It integrates into C/C++ projects by adding a few source files and using its API to call JavaScript from C and vice versa.

Use cases

• embed a JavaScript scripting engine in a C/C++ application
• add user scripting/plugin support to an embedded device
• run ECMAScript in a low-memory environment
• evaluate JavaScript from C code without Node.js
• script game or IoT device logic in JavaScript

When to choose

• you need a small, portable JS engine with minimal platform dependencies
• you want easy C/C++ integration with just a few source files
• you target embedded or resource-constrained platforms
• you need ES5 compliance with coroutines, Proxy subset, and bytecode dump/load

When to avoid

• you need full modern ES2015+/ES2020+ support
• you need maximum JavaScript execution performance (V8/JavaScriptCore are faster)
• you want a standalone JavaScript runtime rather than an embeddable engine
• you need active feature development (project is in maintenance mode)
