AI-Powered

Your AI coding
co-pilot, built in.

AI Explain — Streaming
Click AI Explain on any compiler and watch a real-time token-by-token explanation of your code appear live in a modal. Powered by GPT-4.1 Nano with markdown rendering. Cached in localStorage — same code = instant replay.
Fix with AI
Got an error? Hit Fix with AI and the broken code is automatically rewritten and loaded back into the editor in one click.
Matplotlib Plot Rendering
Python compiler supports matplotlib, numpy, and pandas natively. Any plt.show() call renders the plot as an inline PNG in the output box.
python_code.py
import matplotlib.pyplot as plt
import numpy as np

# Generate sine wave
x = np.linspace(0, 2 * np.pi, 100)
y = np.sin(x)

plt.figure(figsize=(6, 3))
plt.plot(x, y, color='#7c3aed', linewidth=2)
plt.title('Sine Wave')
plt.show() # renders inline ↓

Your own cloud Codespace

Spin up a full VS Code Web workspace in one click — persistent storage, Docker inside, and a stable private URL. Just like GitHub Codespaces, built right in.

Full VS Code in the browser
A real code-server IDE — extensions, integrated terminal, themes — at yourname.goconews.in.
Persistent storage
Your files live on the server. Stop, delete, or redeploy — your projects always come back.
Docker inside the workspace
Build and run your own containers from the terminal — docker run just works.
Private & secure
Password-protected login, isolated per user, served over HTTPS with a wildcard certificate.

Simple workflow

Three steps to run your code

1
Choose a Language
Pick from 9 languages — Python, C, C++, Java, Go, Node.js, PHP, HTML, or PHP Web. Each has its own dedicated compiler.
2
Write Your Code
Use the syntax-highlighted CodeMirror editor. Paste existing code or start from scratch — no installation needed.
3
Run & Explore AI
Click Run Code to execute instantly. Use AI Explain to understand it, or Fix with AI to correct any errors.
Built-in AI Tools

Two AI superpowers,
on every compiler.

No external tools. No copy-pasting into ChatGPT. Both features live inside every compiler page.

Fix with AI

Broken code? Fixed
in one click.

Run your code, get an error — then hit Fix with AI. The AI reads both your code and the error message, rewrites the broken parts, and loads the corrected code directly back into the editor. No copy-paste needed.

  • Reads the actual runtime error output
  • Returns only the corrected code — no fluff
  • Available on all 9 language compilers
  • Powered by GPT-4.1 Nano
Before — buggy code
def greet(name)
    print("Hello, " + name

greet("World")
Fix with AI
After — fixed code
def greet(name):
    print("Hello, " + name)

greet("World")
# ✓ Syntax fixed automatically
AI Explain

Understand any code,
line by line — live.

Click AI Explain and a beautiful modal slides in with a real-time streaming explanation — token by token, as it's generated. Markdown-rendered, cached in localStorage so the same code is instant on repeat visits.

  • Live token-by-token streaming response
  • Markdown rendered with headings, lists & code
  • Cached — same code shows instantly next time
  • Works on all 9 language compilers
AI Explanation Live
✕
def greet(name): print("Hello, " + name)
This Python function greet takes one argument name and prints a greeting.

  • The def keyword defines a function
  • print() outputs text to the console
Secure by default

Every run is sandboxed
inside Docker.

Untrusted user code runs in isolated Docker containers with strict resource limits. Your host server is fully protected.

CPU & Memory Limits
Each container is capped at 512 MB RAM and 1 CPU to prevent resource exhaustion.
Network Disabled
Execution containers have zero network access — no outbound connections from user code.
60-Second Timeout
Infinite loops are automatically killed after 60 seconds with a clear timeout message.
Capability Drops
All Linux capabilities dropped. No privilege escalation, no setuid binaries, no fork bombs.
