⚡ PocketPy IDE & Cross-Platform Runtime

PocketPy IDE is an ultra-fast, lightweight, cross-platform Python IDE and standalone runtime powered by the embeddable PocketPy C11 engine with over 160+ native system, network, crypto, and hardware extensions.

Every single script, network service, and system command runs identically across Android, Windows, and Linux.

While traditional Python mobile distributions (like Chaquopy or Termux CPython) require massive 80–120 MB downloads and suffer from sluggish interpreter cold starts, PocketPy IDE delivers full script execution, live syntax highlighting, an ANSI streaming terminal, HTML5/SVG visualization, and comprehensive system control in an astonishing 2.94 MB APK footprint with sub-20ms instant boot. On Windows, the entire standalone CLI compiler and runtime packs all 160+ native functions into a tiny ~359 KB binary.

💻 CLI Runner Usage (Windows, Linux, macOS)

PocketPy includes a standalone CLI binary (pocketpy.exe on Windows or ./pocketpy on Linux):

1. Interactive REPL

Simply launch the binary to start the interactive prompt:

pocketpy

PocketPy 2.0 (C11 Runtime with 160+ Native Extensions)
Type 'exit()' or press Ctrl+C / Ctrl+D to quit.
>>> import socket, sys, os
>>> print("Running on:", sys.platform, "OS:", os.name)
Running on: win32 OS: nt
>>> socket.gethostname()
'My-Desktop-PC'

2. Execute Code Directly (-c)

pocketpy -c "import hashlib; print(hashlib.sha256(b'hello'))"
# 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824

3. Run Scripts with Arguments

pocketpy script.py arg1 arg2

4. Run the Exhaustive Test Suite

pocketpy tests/test_full_suite.py
# ================================================================
# TEST RESULTS: 142 PASSED, 0 FAILED (TOTAL: 142)
# ALL TESTS PASSED WITH 100% SUCCESS!
# ================================================================
