The compiler, without the circus
Write, run, and share Python in the browser.
Instant execution
Code runs locally via Pyodide. No server round-trips.
PyPI packages
Import NumPy, Pandas, Requests — micropip installs on first run.
Charts
Matplotlib, Plotly, and Pillow render in the Output panel.
Multi-file
Several files, imports between them, same as a real project.
Shareable URLs
One link. Anyone can view and run the project.
Private run
Execution never leaves the browser.
Install a package. Just import it.
Unlike toy compilers, this one talks to PyPI through micropip.

x = np.linspace(0, 2 * np.pi, 100)
plt.plot(x, np.sin(x))
plt.show()
