Pygantry – Why ship a whole OS when you just need a Python environment?
"Hi Hacker News, I’ve always found Docker to be overkill for simple Python deployments. It's heavy, complex for non-tech users, and often results in 500MB+ images for a 10KB script. That’s why I built Pygantry. It’s a minimalist 'container' engine based on Python venv but made portable and relocatable. Key features: Lightweight: A full 'shipped' app is usually < 20MB. Zero-Config: No daemon, no root, no Dockerfile complexity. Portable: Build once, zip it, and run it anywhere with a Python interpreter. Founder friendly: Built-in licensing and stealth modes for those building a business. I…

I'd love to get your feedback on the architecture and how you handle 'Docker-fatigue' in your workflow.

Read an article about analyzing Garmin data with AI. Sounded great — except I didn't want to send my health data to any cloud service. So I asked Claude to write me 2-3 scripts and a dashboard. This escalated a bit. 30 days and 20$ later I have this: A local-first Garmin archive with interactive HTML dashboards, Excel exports, weather and pollen context, AES-256 encrypted token storage, and a self-healing data pipeline with 515 automated tests. Windows desktop app, no terminal needed. Nothing leaves your machine. I never wrote a line of Python. I understood the problems and made the…
