README

Elide is a high-performance multi-language software runtime, powered by GraalVM. Here you can find reference docs, guides, code samples, and more.

Highlights

🚀 Elide is a runtime, like Node or Python.

You install it on your machine as a standalone binary. Elide is statically linked and has essentially zero runtime dependencies.

You can install it on macOS or Linux with this one-liner:

curl -sSL --tlsv1.2 elide.sh | bash -s -

🗺️ Elide can run multiple languages.

JavaScript, TypeScript, WASM, and Python are built-in. Ruby, JVM (Java, Kotlin, Scala), and LLVM (Swift, C++, Rust) are on the way.

// hello.ts
import py from "./my-app.py"

// this line exists to show that this is typescript
const msg: () => string = () => `${py.say_hello()} + TypeScript!`
console.log(JSON.stringify({greeting: msg()}))

def say_hello():
  """Render a greeting."""
  return f"Hello from Python"

elide ./hello.ts

{"greeting": "Hello from Python + TypeScript!"}

⏫ Elide is extremely fast.

☑️ Elide runs your Python code up to 3x faster than CPython.
☑️ Elide runs your TypeScript code faster than Node can run JavaScript.
☑️ Elide runs your HTTP endpoints at up to 800k RPS. That's really fast.

🧘 Elide supports the APIs you already know and the tools you already love.

☑️ Elide is WinterTC compatible and passes Test262
☑️ Like other JS runtimes, Elide supports a large slice of the Node API.
☑️ Works with NPM and PyPI, CJS and ESM.
☑️ Insanely fast dependency installation (via orogene and uv).
☑️ Elide supports embedded SQLite.

🔒 Elide provides strong security boundaries and memory safety by default.

☑️ Written in memory-safe Kotlin and Rust.
☑️ Strong filesystem and environment isolation.
☑️ Virtualized filesystem support (mount a tarball as your fs!).
☑️ Extensively tested: over 10,000 unit & conformance tests, in addition to Test262.
