Tengo is a small, dynamic, fast scripting language implemented in pure Go, compiled to bytecode and executed on a stack-based VM. It is designed to be securely embedded in Go applications as an extensible scripting/rules layer, and also ships as a standalone CLI with a REPL.

Use cases

• embed a scripting language in a go application
• build a rules engine with user-editable logic
• run sandboxed user scripts securely
• write a data pipeline in a small dynamic language
• evaluate dynamic expressions at runtime in go
• use a lightweight scripting language with a REPL

When to choose

• you need a fast, dependency-free embeddable script language for Go
• security and sandboxing of user-supplied scripts matter
• you want better VM performance than Lua/JS interpreters on Go

When to avoid

• you need a rich standard library or large ecosystem
• you need native-code performance
• you prefer a mature mainstream scripting language like Lua or JavaScript
