codenire

Сodenire Playground

Open-source online code execution system featuring a playground and sandbox. Built on Docker images with robust isolation provided by Google gVisor.

The system is easily extensible with additional technologies and languages.

Inspired by:

• Judje0 Playground: https://github.com/judge0/judge0
• Google Playground: https://github.com/golang/playground

But created for more extensible

*Playground demonstration in the codiew.io/ide

🌟Features

• Multi-Language Support: Run Python, Go, PHP and Node.js or your built code with others configurations and versions what you can think, in isolated Docker containers.
• Multi-Files Support: Run code that consists of multiple files.
• Easy extensible: You can create your own build to run code via API or by loading a folder with configurations at startup.
• (in working) Dependency Management: Automatic handling of project dependencies (pip, go mod, npm).
• Flexible Execution: Custom entrypoints for both single-file code and full projects.
• Scalable System: Expandable via a load balancer between a playground and a sandbox.
• Security: You can accept JWTS signed external system (Supabase JWT Secret Token for example)
• PostgresQL supported
• CORS supported

🐙Infrastructure Schema

Sandbox Provision Templates Schema

[!] The ability to register Docker images via API is not yet implemented and will be available in the near future!

Out of the box (in development), Dockerfiles and configurations for various languages can be found in /sandbox/dockerfiles

Run/Set Up

You can Run Playground local (or on MacOS/Ubuntu) via Docker Compose.

[!] If you start on MacOS you can't start with gVisor Environment

  playground:
    container_name: play_dev
    build:
      context: .
      dockerfile: Dockerfile
    ports:

Deploy

• Docker compose (see /docs/docker-compose dir — without external gVisor Runtime)
• Digital Ocean Terraform with load balancing and multi-sandbox cluster

Roadmap

• Add MultiFiles/singe scripts
• Add gVisor Isolation - [x] Add Hooks to catch/override some request (for auth, for handle code in external system)
• Add Multi actions in once container (different runs in one docker img, for example multi version of c++ in cpp container)
• Add WebUI Head with Monaco
• Add Metrics
• Add Tests
• Add GoLinter
  • Playground
  • Sandbox
• Add debug info in API req/resp
• Change container replica strategy
• Add StateFull sandbox
• Compile with open network
• Add WS messaging
• Add action create route - [ ] Add out provider of templates (S3...)
