// como funciona

Como funciona

  1. Choose CE or Extra CE

    Pick the flavor whose language set matches the languages you need to run.

  2. Self-host or use the cloud

    Follow the README's installation guide to self-host, or sign up for the managed service.

  3. Install a client

    Use raw HTTP from any language, or the official Python SDK.

  4. Run your first submission

    POST source code to the submissions endpoint and read back status, stdout, and timing.

// recursos

Por que as pessoas gostam tanto

Simple HTTP API

Create submissions with a POST and poll (or use ?wait=true) for results — language-agnostic by design.

Sandboxed execution

Untrusted code is compiled and run in a sandbox with configurable time and memory limits.

Rich submission options

Multi-file programs, additional files, custom compiler options and command-line arguments.

Detailed results

Status, stdout/stderr, compile output, time, and memory for every run.

Webhooks

Get notified when submissions finish instead of polling.

Official Python SDK

A maintained judge0 package on PyPI wraps the API for Python applications.

    # see the installation guide linked from the README for the exact commands
  3. Submit your first program

    From Python, install the SDK and run a snippet against your instance or the cloud.

    pip install judge0
    import judge0
    result = judge0.run(source_code="print('hello')", language=judge0.Python)

Perguntas frequentes

Who maintains Judge0?

Judge0 was created by Herman Zvonimir Došilović in 2016 and is maintained as an open-source project, with a managed cloud offered at judge0.com.

Is Judge0 free?

The self-hosted system is GPL-3.0 open source. A hosted cloud version is also available for those who don't want to run infrastructure.

Does it need a paid API key?

Self-hosted Judge0 needs no key. The managed cloud is a separate service with its own access arrangements.

How does it compare to running code with Docker yourself?

Judge0 gives you the whole execution platform — queueing, sandboxing, limits, result reporting, and webhooks — behind one API, instead of building and securing that pipeline yourself.

How do I get started?

Follow the installation guide linked from the README to self-host, or `pip install judge0` and run your first submission against an instance.
