What is Elixir?
Elixir is a functional, concurrent language built on the Erlang Virtual Machine (BEAM). It leverages Erlang's thirty-year-old, battle-tested process model — the same runtime that powers WhatsApp, Discord, and the entire Ericsson telecom stack — to deliver low-latency, fault-tolerant services with hot-code reloads.
Why run Elixir in the browser
Installing Erlang + Elixir + Mix takes five-plus minutes and a 200MB+ toolchain on most platforms. A browser sandbox is faster for trying a pattern match, validating a GenServer skeleton, or teaching the language at a workshop where attendees just want to see what an actor looks like.
Common Elixir tasks
Phoenix web apps with real-time channels and Presence, OTP behaviours (GenServer, Supervisor, Application), Broadway data pipelines, Nerves firmware for embedded devices, and machine-learning pre-processing via the Nx tensor library. The sandbox runs Elixir 1.11.3.
Getting started with Elixir 1.11.3
Paste a snippet — defmodule H do; def greet(n), do: IO.puts "hi, #{n}"; end; H.greet("Tutorsbot") — hit Run, see stdout. The highlighter recognises Elixir idioms: the pipe operator |>, sigils ~r/regex/ and ~w(a b c), the keyword-list shorthand [key: value], and pattern matching with <>.

Frequently Asked Questions
- Is the Elixir online compiler free?
- Yes — Tutorsbot's Elixir compiler is completely free. No account required, no installation, and no usage limits.
- Do I need to install Elixir?
- No. The Elixir compiler runs entirely in your browser. No runtime, no SDK, no PATH configuration. Open the page and start coding.
- Is my Elixir code saved between sessions?
- Yes — your code autosaves to your browser's local storage so you can resume where you left off. You can also generate a shareable URL.
- Can I share Elixir code with others?
- Yes. Click the Share button to copy a URL that encodes your script. Anyone with the link can open and run it instantly — no account required on their end.
- Is the Elixir compiler safe to use?
- Absolutely. Every program runs in an isolated sandbox. Your local system is never exposed to the executed code, and nothing is persisted after the execution window.
