Playground

Try Endo directly in your browser. This runs the real Endo interpreter compiled to WebAssembly — no installation needed.

Quick start

Type an expression and press Enter to evaluate. Try println "Hello, Endo!" to get started, or click an example above.

Limitations

The playground runs a sandboxed subset of Endo. Shell commands, file I/O, and network access are not available. Standard library functions for strings, lists, pattern matching, and arithmetic work as expected.
