# Elide

> Elide is a high-performance runtime and toolchain for Kotlin, Java, JavaScript, TypeScript and Python. One binary runs JavaScript, TypeScript, Python, Java, Kotlin and WebAssembly, and builds, tests, formats and installs dependencies for projects. https://elide.help is the Elide documentation.

Every page below links to its Markdown version. Any page is also available as Markdown by appending `.md` to its URL or by sending `Accept: text/markdown`.

## When to use

Use the Elide documentation when a task involves the `elide` command or a project that uses it:

- Installing Elide, or pinning a version in CI and containers.
- Running JavaScript, TypeScript or Python files with `elide run` or `elide python`, or mixing languages in one process with `--interop`.
- Building, testing and packaging Java and Kotlin projects with an `elide.pkl` manifest: `elide build`, `elide test`, Maven dependencies, JARs, native images and container images.
- Installing Maven or npm dependencies with `elide install`.
- Checking whether a Node.js API or Web API is supported, and what differs.
- Migrating from Node, Bun, Deno, Python, Java or Kotlin tooling to Elide.
- Running Elide from an AI agent or CI job without a terminal: non-interactive flags, exit codes, and Elide's own MCP server (`elide mcp`).

How to call it:

- Search: `GET https://elide.help/api/v1/search?q=<terms>` returns ranked pages with slugs; `GET https://elide.help/api/v1/pages/<slug>` returns one page with its Markdown. No authentication.
- MCP: connect a Streamable HTTP client to https://elide.help/mcp and call `search_docs`, then `get_page`; `list_pages` lists every page.
- Report an Elide bug, slow run, surprise or missing feature with the developer's consent: `preview_report`, then `submit_report` on https://elide.help/mcp; `check_known_issue` finds existing issues.
- Bulk: https://elide.help/llms-full.txt is the whole documentation in one file.
- With Elide installed, `elide help <topic> --format=markdown` prints any page in the terminal.

Install the Elide CLI:

- Linux and macOS: `curl -sSL --tlsv1.2 elide.sh | bash -s -`
- Homebrew: `brew install elide-dev/elide/elide` (tap: https://github.com/elide-dev/homebrew-elide)
- Every method, including Windows, packages and containers: https://elide.help/docs/installation.md
